From df46b9a44ceb5af2ea2351ce8e28ae7bd840b00f Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Mon, 20 Jun 2005 14:04:44 +0200 Subject: [PATCH] Add blk_rq_map_kern() Add blk_rq_map_kern which takes a kernel buffer and maps it into a request and bio. This can be used by the dm hw_handlers, old sg_scsi_ioctl, and one day scsi special requests so all requests comming into scsi will have bios. All requests having bios should allow scsi to use scatter lists for all IO and allow it to use block layer functions.

The thing is that 'cscope.el' does not allow setting the command line options to the 'cscope' commands it runs, and it errors with a message about the options not matching the ones used to generate the index. It turns out the cscope designers already thought of this. The options can be written into the "cscope.files". The included patch moves the "-q" and "-k" options from the 'cmd_cscope' to the 'cmd_cscope-file', echoing them into the top of the files listing. Now the index is generated with the "-q" option, and when 'cscope.el' performs it's search, it uses that argument as well. Lookups are fast and everyone is happy.

On the other hand, we want to use /usr/src/linux as read-only source for building kernels or additional modules.

Different kbuild usage scenarios: make - plain make in same directory where kernel source lives make O= - kbuild is told to store output files in another directory make M= - building an external module make O= M= - building an external module with kernel output seperate from src Value assigned to the different variables: |$(src) |$(obj) |$(srctree) |$(objtree) make |reldir to k src |as src |abs path to k src |abs path to k src make O= |reldir to k src |as src |abs path to k src |abs path to output dir make M= |abs path to src |as src |abs path to k src |abs path to k src make O= M= |abs path to src |as src |abs path to k src |abs path to k output path to kbuild file: make | $(srctree)/$(src), $(src) make O= | $(srctree)/$(src) make M= | $(src) make O= M= | $(src) From the table above it can be seen that the only good way to find the home directory of the kbuild file is to locate the one of the two variants that is an absolute path. If $(src) is an absolute path (starts with /) then use it, otherwise prefix $(src) with $(srctree).

If you set the bit immediately, you get into the situation where the transport parameters report something as being set even if the drive cannot support it. I patched the driver to do it this way and also corrected a panic in the proc routines.

This reduced the PCI traffic in the driver to submit a command to the queue to near zero allowing a significant number of commands to be turned around with no need to block for the PCI bridge to flush the notify request to the adapter. Interrupt mitigation has always been present in the driver; it was turned off because of a bug that prevented one from realizing the usefulness of the feature. This bug is fixed in this patch.

The timeout is there to clean up should the management application die and fail to poll for updated AIF event packets. Moving the timer update from the ioctl code that delivers an AIF to the polling registrant to the bottom of the ioctl means the timeout is reset with any management application polling activity regardless if an AIF is delivered or not removing the erroneous timeout cleanups.

Brian King has acknowledged that it fixes the problems he has seen. Seems mature enough for inclusion into 2.6.14 (or later)? Nate's explanation of the changes: I've attached patches against 2.6.13rc2. These are basically identical to my earlier patches, as I found that all issues I'd seen in earlier kernels still existed in this kernel. To summarize, the changes are: (more details in my original email) - add a kref to the scsi_tape structure, and associate reference counting stuff - set sr_request->end_io = blk_end_sync_rq so we get notified when an IO is rejected when the device goes away - check rq_status when IOs complete, else we don't know that IOs rejected for a dead device in fact did not complete - change last_SRpnt so it's set before an async IO is issued (in case st_sleep_done is bypassed) - fix a bogus use of last_SRpnt in st_chk_result Signed-off-by: Nate Dailey Signed-off-by: Kai Makisara Signed-off-by: James Bottomley diff --git a/drivers/scsi/st.c b/drivers/scsi/st.c index 0291a8f..47a5698 100644 --- a/drivers/scsi/st.c +++ b/drivers/scsi/st.c @@ -17,7 +17,7 @@ Last modified: 18-JAN-1998 Richard Gooch Devfs support */ -static char *verstr = "20050501"; +static char *verstr = "20050802"; #include @@ -219,6 +219,12 @@ static int switch_partition(struct scsi_tape *); static int st_int_ioctl(struct scsi_tape *, unsigned int, unsigned long); +static void scsi_tape_release(struct kref *); + +#define to_scsi_tape(obj) container_of(obj, struct scsi_tape, kref) + +static DECLARE_MUTEX(st_ref_sem); + #include "osst_detect.h" #ifndef SIGS_FROM_OSST @@ -230,6 +236,46 @@ static int st_int_ioctl(struct scsi_tape *, unsigned int, unsigned long); {"OnStream", "FW-", "", "osst"} #endif +static struct scsi_tape *scsi_tape_get(int dev) +{ + struct scsi_tape *STp = NULL; + + down(&st_ref_sem); + write_lock(&st_dev_arr_lock); + + if (dev < st_dev_max && scsi_tapes != NULL) + STp = scsi_tapes[dev]; + if (!STp) goto out; + + kref_get(&STp->kref); + + if (!STp->device) + goto out_put; + + if (scsi_device_get(STp->device)) + goto out_put; + + goto out; + +out_put: + kref_put(&STp->kref, scsi_tape_release); + STp = NULL; +out: + write_unlock(&st_dev_arr_lock); + up(&st_ref_sem); + return STp; +} + +static void scsi_tape_put(struct scsi_tape *STp) +{ + struct scsi_device *sdev = STp->device; + + down(&st_ref_sem); + kref_put(&STp->kref, scsi_tape_release); + scsi_device_put(sdev); + up(&st_ref_sem); +} + struct st_reject_data { char *vendor; char *model; @@ -311,7 +357,7 @@ static int st_chk_result(struct scsi_tape *STp, struct scsi_request * SRpnt) return 0; cmdstatp = &STp->buffer->cmdstat; - st_analyze_sense(STp->buffer->last_SRpnt, cmdstatp); + st_analyze_sense(SRpnt, cmdstatp); if (cmdstatp->have_sense) scode = STp->buffer->cmdstat.sense_hdr.sense_key; @@ -399,10 +445,10 @@ static void st_sleep_done(struct scsi_cmnd * SCpnt) (STp->buffer)->cmdstat.midlevel_result = SCpnt->result; SCpnt->request->rq_status = RQ_SCSI_DONE; - (STp->buffer)->last_SRpnt = SCpnt->sc_request; DEB( STp->write_pending = 0; ) - complete(SCpnt->request->waiting); + if (SCpnt->request->waiting) + complete(SCpnt->request->waiting); } /* Do the scsi command.

This code will apply a global timeout (of the total number of retries times the per command timer) to a given command. If it is exceeded, the command is completed regardless of its state. The patch also removes the unused field in the command: timeout and timeout_total. This solves the problem of detecting an endless loop in the mid-layer because of BUSY/QUEUE_FULL bouncing, but will not recover the device. In the aic7xxx case, the driver can be recovered by sending a bus reset, so possibly this should be tied into the error handler?

It converts scsi_wait_req to do correct REQ_BLOCK_PC submission (and works nicely in my setup). The final goal should be to eliminate struct scsi_request, but that can't be done until the character submission paths of sg and st are also modified.

Try to do this on 2.6.12: - Kill udev and HAL - Insert a CD-ROM into a SCSI or USB CD-ROM drive - Run dd if=/dev/scd0 - cat /sys/block/sr0/size - Eject the CD, insert a different one - Run dd if=/dev/scd0 This is likely to do "access beyond the end of device", if you let it - cat /sys/block/sr0/size This shows the size of a previous CD, even though dd was supposed to revalidate the device. - Run dd if=/dev/scd0 The second run of dd works correctly! The bug was introduced in 2.5.31, when Al fixes the recursive opens in partitioning. Before, the code worked like this: - Block layer called cdrom_open directly - cdrom_open called sr_open - sr_open called check_disk_change - check_disk_change called sr_media_change - sr_media_change did cd->needs_disk_change=1 - before returning sr_open tested cd->needs_disk_change and called get_sector_size. In 2.6.12, the check_disk_change is called from cdrom_open only. Thus: - Block layer calls sr_bd_open - sr_bd_open calls cdrom_open - cdrom_open calls sr_open - sr_open tests cd->needs_disk_change, which wasn't set yet; returns - cdrom_open calls check_disk_change - check_disk_change calls sr_media_change - sr_media_change does cd->needs_disk_change=1, but nobody cares Acked by: Alexander Viro Signed-off-by: James Bottomley diff --git a/drivers/scsi/sr.c b/drivers/scsi/sr.c index 2f259f2..f63d8c6 100644 --- a/drivers/scsi/sr.c +++ b/drivers/scsi/sr.c @@ -199,15 +199,7 @@ int sr_media_change(struct cdrom_device_info *cdi, int slot) /* check multisession offset etc */ sr_cd_check(cdi); - /* - * If the disk changed, the capacity will now be different, - * so we force a re-read of this information - * Force 2048 for the sector size so that filesystems won't - * be trying to use something that is too small if the disc - * has changed. - */ - cd->needs_sector_size = 1; - cd->device->sector_size = 2048; + get_sectorsize(cd); } return retval; } @@ -538,13 +530,6 @@ static int sr_open(struct cdrom_device_info *cdi, int purpose) if (!scsi_block_when_processing_errors(sdev)) goto error_out; - /* - * If this device did not have media in the drive at boot time, then - * we would have been unable to get the sector size.

The transport class uses REQ_FAILFAST, so another interface (scsi_execute) had to be invented to take the extra flag. Also, the sense functions are shifted around to allow spi_execute to place data directly into a struct scsi_sense_hdr. With this change, there's probably a lot of unnecessary sense buffer allocation going on which we can fix later.

In the process, I noticed we have no callers of scsi_wait_req who don't immediately normalise the sense, so I updated the API to make it take a struct scsi_sense_hdr instead of simply a big sense buffer.

This, unfortunately, leads to potential scheduling while atomic problems if there's a sleep in the function called by a trigger. The correct solution is to use the kernel klist infrastructure instead which allows lockless traversal of a list.

To do that, I've made this class a transport class that's entirely subsystem independent (although the matching routines have to match per subsystem, as you'll see looking at the code). I put it in the scsi subdirectory purely because I needed somewhere to play with it, but it's not a scsi specific module. I used a fusion raid card as the test bed for this; with that kind of card, this is the type of class output you get: jejb@titanic> ls -l /sys/class/raid_devices/20\:0\:0\:0/ total 0 lrwxrwxrwx 1 root root 0 Aug 16 17:21 component-0 -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:1:0/20:1:0:0/ lrwxrwxrwx 1 root root 0 Aug 16 17:21 component-1 -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:1:1/20:1:1:0/ lrwxrwxrwx 1 root root 0 Aug 16 17:21 device -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:0:0/20:0:0:0/ -r--r--r-- 1 root root 16384 Aug 16 17:21 level -r--r--r-- 1 root root 16384 Aug 16 17:21 resync -r--r--r-- 1 root root 16384 Aug 16 17:21 state So it's really simple: for a SCSI device representing a hardware raid, it shows the raid level, the array state, the resync % complete (if the state is resyncing) and the underlying components of the RAID (these are exposed in fusion on the virtual channel 1). As you can see, this type of information can be exported by almost anything, including software raid. The more difficult trick, of course, is going to be getting it to perform configuration type actions with writable attributes.

This is incorrect since spin locks don't always cause in_atomic() to return true. Instead of that, this patch returns to an earlier idea of a per-tfm flag which determines whether sleeping is allowed. Unlike the earlier version, the default is to not allow sleeping. This ensures that no existing code can break. As usual, this flag may either be set through crypto_alloc_tfm(), or just before a specific crypto operation.

This patch removes the redundant NULL checks and also a few similar checks for NULL before calls to kfree() that I ran into while doing the crypto_free_tfm bits. I've succesfuly compile tested this patch, and a kernel with the patch applied boots and runs just fine. When I posted the patch to LKML (and other lists/people on Cc) it drew the following comments : J. Bruce Fields commented "I've no problem with the auth_gss or nfsv4 bits.--b." Sridhar Samudrala said "sctp change looks fine." Herbert Xu signed off on the patch. So, I guess this is ready to be dropped into -mm and eventually mainline.

Due to changes to enforce checking interface bindings, sockets did not see loopback packets bound for our local address on our interface. e.g.) When we ping6 fe80::1%eth0, skb->dev points loopback_dev while IP6CB(skb)->iif indicates eth0. This patch fixes the issue by using appropriate incoming interface, in the sense of scoping architecture. Signed-off-by: YOSHIFUJI Hideaki Signed-off-by: David S.

When tcp_sendmsg tacks on extra bits to an existing TCP_PAGE we don't check sk_forward_alloc even though a large amount of time may have elapsed since we allocated the page. In the mean time someone could've come along and liberated packets and reclaimed sk_forward_alloc memory. This patch makes tcp_sendmsg check sk_forward_alloc every time as we do in do_tcp_sendpages.

On tyan motherboards for e.g. you can init the watchdog to 4 mins, then when the driver is loaded it sets the watchdog to "seconds" mode, and then machine will reboot within 4 seconds. So this patch resets the timeout to the configured value if the watchdog is already running.

Load the module without the nowayout option. 2. Open the driver and close it without writing 'V' before close. 3. Unload the module. The timer will continue to run... 4. Oops happens when timer fires. Reported Sun, 10 Oct 2004, by Michael Schierl Fix is easy: always take a reference on the module on open. Release it only when the device is closed and no timer is running. Tested on 2.6.13-rc6 using the soft_noboot option. While the timer is running and the device is closed, the module use count stays at 1. After the timer fires, it drops to 0. Repeatedly opening and closing the driver caused no problems. Please apply.

Architecture platforms with a very sparse physical address space would likely want to select this option. For those architecture platforms that don't select the option, the code generated is equivalent to SPARSEMEM currently in -mm. I'll be posting a patch on ia64 ml which uses this new SPARSEMEM feature. ARCH_SPARSEMEM_EXTREME makes mem_section a one dimensional array of pointers to mem_sections. This two level layout scheme is able to achieve smaller memory requirements for SPARSEMEM with the tradeoff of an additional shift and load when fetching the memory section. The current SPARSEMEM -mm implementation is a one dimensional array of mem_sections which is the default SPARSEMEM configuration. The patch attempts isolates the implementation details of the physical layout of the sparsemem section array. ARCH_SPARSEMEM_EXTREME depends on 64BIT and is by default boolean false. I've boot tested under aim load ia64 configured for ARCH_SPARSEMEM_EXTREME. I've also boot tested a 4 way Opteron machine with !ARCH_SPARSEMEM_EXTREME and tested with aim.

This two level layout scheme is able to achieve smaller memory requirements for SPARSEMEM with the tradeoff of an additional shift and load when fetching the memory section. The current SPARSEMEM implementation is a one dimensional array of mem_sections which is the default SPARSEMEM configuration. The patch attempts isolates the implementation details of the physical layout of the sparsemem section array. SPARSEMEM_EXTREME requires bootmem to be functioning at the time of memory_present() calls. This is not always feasible, so architectures which do not need it may allocate everything statically by using SPARSEMEM_STATIC.

While scanning for an empty cluster, don't worry that racing tasks may allocate what was free and free what was allocated; but when allocating an entry, check it's still free after retaking the lock. Avoid dropping the lock in the expected common path. No barriers beyond the locks, just let the cookie crumble; highest_bit limit is volatile, but benign. Guard against swapoff: must check SWP_WRITEOK before allocating, must raise SWP_SCANNING reference count while in scan_swap_map, swapoff wait for that to fall - just use schedule_timeout, we don't want to burden scan_swap_map itself, and it's very unlikely that anyone can really still be in scan_swap_map once swapoff gets this far.

The only exceptions have been swap_duplicate, valid_swaphandles and an untrodden path in try_to_unuse (plus a few places added in this series). valid_swaphandles doesn't show up high in profiles, but swap_duplicate does demand attention. However, with the hold time in get_swap_pages so much reduced, I've not yet found a load and set of swap device priorities to show even swap_duplicate benefitting from the split. Certainly the split is mere overhead in the common case of a single swap device. So, replace swap_list_lock and swap_device_lock by spinlock_t swap_lock (generally we seem to prefer an _ in the name, and not hide in a macro). If someone can show a regression in swap_duplicate, then probably we should add a hashlock for the swap_map entries alone (shorts being anatomic), so as to help the case of the single swap device too.

There was a small patch in there that I find to be very useful since it allows the display of the locality of the pages in use by a process. I reworked that patch and came up with a /proc//numa_maps that gives more information about the vma's of a process. numa_maps is indexes by the start address found in /proc//maps.

However, on MIPS (alone) there's not one but as many as eight ZERO_PAGEs, chosen for coloring by user virtual address; and if mremap has meanwhile been used to move a mapping containing a ZERO_PAGE, it will generally not match the ZERO_PAGE(address) __xip_unmap is looking for. To maintain XIP's established mappings correctly on MIPS, we need Nick's fix to mremap's move_one_page (originally presented as an optimization), to replace the ZERO_PAGE appropriate to the old address by the ZERO_PAGE appropriate to the new address. (But when I first saw this, I was thinking the ZERO_PAGEs themselves would get corrupted, very bad. Now I think it's the other way round, that the established mappings will fail to see the newly written data: incorrect, but not corrupting everything else. Whether filemap_xip's technique is generally safe, I'd hesitate to say in a hurry: it's interesting, but we've never tried to do that in tmpfs.)

Remove a pointless check and fix two little bugs - a simple test (with /proc//maps hacked to show ReadHints) showed both mismerges in practice: though being madvise, neither was disastrous. 1. Correct placement of the success label in madvise_behavior: as in mprotect_fixup and mlock_fixup, it is necessary to update vm_flags when vma_merge succeeds (to handle the exceptional Case 8 noted in the comments above vma_merge itself). 2. Correct initial value of prev when starting part way into a vma: as in sys_mprotect and do_mlock, it needs to be set to vma in this case (vma_merge handles only that minimum of cases shown in its comments). 3. If find_vma_prev sets prev, then the vma it returns is prev->vm_next, so it's pointless to make that same assignment again in sys_madvise.

In trying to add support for ioremap() of 36-bit I/O, we run into the issue that get_vm_area() allows for a maximum of 512K alignment via the IOREMAP_MAX_ORDER constant. To work around this, we can: - Allocate a larger VM area than needed (size + (1ul << IOREMAP_MAX_ORDER)) and then align the pointer ourselves, but this ends up with 512K of wasted VM per ioremap(). - Provide a new __get_vm_area_aligned() API and make __get_vm_area() sit on top of this. I did this and it works but I don't like the idea adding another VM API just for this one case. - My preferred solution which is to allow the architecture to override the IOREMAP_MAX_ORDER constant with it's own version.

It happens > if the virtual address for hugetlb mmap is recycled from previously used > normal page mmap. free_pgtables() might not scrub the pmd entry on > munmap and hugetlb_prefault skips on any pmd presence regardless what type > it is. Unless I am missing something, it seems more correct to place the check inside huge_pte_alloc() to prevent a the same bug wherever a huge pte is allocated. It also allows checking for this condition when lazily faulting huge pages later in the series.

It now collect all the pte page at the time of munmap. It used to only collect page table pages when entire one pgd can be freed and left with staled pte pages. Not anymore with 2.6.13. This function will never be called and We should turn it into a BUG_ON. I also spotted two problems here, not Adam's fault :-) (1) in huge_pte_alloc(), it looks like a bug to me that pud is not checked before calling pmd_alloc() (2) in hugetlb_clean_stale_pgtable(), it also missed a call to pmd_free_tlb. I think a tlb flush is required to flush the mapping for the page table itself when we clear out the pmd pointing to a pte page. However, since hugetlb_clean_stale_pgtable() is never called, so it won't trigger the bug.

this allows architectures with hardware pagetables to optimize away atomic PTE operations when destroying an address space. Removing the locked operation should allow better pipelining of memory access in this loop. I measured an average savings of 30-35 cycles per zap_pte_range on the first 500 destructions on Pentium-M, but I believe the optimization would win more on older processors which still assert the bus lock on xchg for an exclusive cacheline. Update: I made some new measurements, and this saves exactly 26 cycles over ptep_get_and_clear on Pentium M. On P4, with a PAE kernel, this saves 180 cycles per ptep_get_and_clear, for a whopping 92160 cycles savings for a full address space destruction. pte_clear_full is not yet used, but is provided for future optimizations (in particular, when running inside of a hypervisor that queues page table updates, the full hint allows us to avoid queueing unnecessary page table update for an address space in the process of being destroyed. This is not a huge win, but it does help a bit, and sets the stage for further hypervisor optimization of the mm layer on all architectures.

So the new features are the physical size of shared and clean [or dirty]; private and clean [or dirty]. Take a look the example below: # cat /proc/4576/smaps 08048000-080dc000 r-xp /bin/bash Size: 592 KB Rss: 500 KB Shared_Clean: 500 KB Shared_Dirty: 0 KB Private_Clean: 0 KB Private_Dirty: 0 KB 080dc000-080e2000 rw-p /bin/bash Size: 24 KB Rss: 24 KB Shared_Clean: 0 KB Shared_Dirty: 0 KB Private_Clean: 0 KB Private_Dirty: 24 KB 080e2000-08116000 rw-p Size: 208 KB Rss: 208 KB Shared_Clean: 0 KB Shared_Dirty: 0 KB Private_Clean: 0 KB Private_Dirty: 208 KB b7e2b000-b7e34000 r-xp /lib/tls/libnss_files-2.3.2.so Size: 36 KB Rss: 12 KB Shared_Clean: 12 KB Shared_Dirty: 0 KB Private_Clean: 0 KB Private_Dirty: 0 KB ... (Includes a cleanup from "Richard Purdie" ) From: Torsten Foertsch show_smap calls first show_map and then prints its additional information to the seq_file. show_map checks if all it has to print fits into the buffer and if yes marks the current vma as written. While that is correct for show_map it is not for show_smap. Here the vma should be marked as written only after the additional information is also written. The attached patch cures the problem. It moves the functionality of the show_map function to a new function show_map_internal that is called with an additional struct mem_size_stats* argument. Then show_map calls show_map_internal with NULL as struct mem_size_stats* whereas show_smap calls it with a real pointer. Now the final if (m->count < m->size) /* vma is copied successfully */ m->version = (vma != get_gate_vma(task))? vma->vm_start: 0; is done only if the whole entry fits into the buffer.

The memory savings are substantial, e.g. on a 64-bit system after boot, James Morris reported the following data for the targeted and strict policies: #objs objsize kernmem Targeted: Before: 237888 40 9.1MB After: 19968 24 468KB Strict: Before: 571680 40 21.81MB After: 221052 24 5.06MB The improvement in memory use comes at a cost in the speed of security server computations of access vectors, but these computations are only required on AVC cache misses, and performance measurements by James Morris using a number of benchmarks have shown that the change does not cause any significant degradation. Note that a rebuilt policy via an updated policy toolchain (libsepol/checkpolicy) is required in order to gain the full benefits of this patch, although some memory savings benefits are immediately applied even to older policies (in particular, the reduction in avtab node size). Sources for the updated toolchain are presently available from the sourceforge CVS tree (http://sourceforge.net/cvs/?group_id=21266), and tarballs are available from http://www.flux.utah.edu/~sds.

This allows security modules to export the incore inode security label information to userspace even if the filesystem does not provide xattr storage, and eliminates the need to individually patch various pseudo filesystem types to provide such access. The patch removes the existing xattr code from devpts and tmpfs as it is then no longer needed. The patch restructures the code flow slightly to reduce duplication between the normal path and the fallback path, but this should only have one user-visible side effect - a program may get -EACCES rather than -EOPNOTSUPP if policy denied access but the filesystem didn't support the operation anyway. Note that the post_setxattr hook call is not needed in the fallback case, as the inode_setsecurity hook call handles the incore inode security state update directly. In contrast, we do call fsnotify in both cases.

The timer has implementation dependent timeout frequencies that can be configured by software. One the first Watchdog timeout we get a critical exception. It is left to board specific code to determine what should happen at this point. If nothing is done and another timeout period expires the processor may attempt to reset the machine. Command line parameters: wdt=0 : disable watchdog (default) wdt=1 : enable watchdog wdt_period=N : N sets the value of the Watchdog Timer Period. The Watchdog Timer Period meaning is implementation specific. Check User Manual for the processor for more details. This patch is based off of work done by Takeharu Kato.

phy excluded features to ocp_func_emac_data This patch adds a field to struct ocp_func_emac_data that allows platform-specific unsupported PHY features to be passed in to the ibm_emac ethernet driver. This patch also adds some logic for the Bamboo eval board to populate this field based on the dip switches on the board. This is a workaround for the improperly biased RJ-45 sockets on the Rev. 0 Bamboo.

PCI busses on MPC83xx and the MPC834x SYS/PIBS reference board. The code initializes PCI inbound/outbound windows, allocates and registers PCI memory/io space. Be aware that setup of the PCI buses on the PIBs board is expected to be done by the firmware.
