2013-04-17powerpc: export debug register save function for KVMBharat Bhushan
KVM need this function when switching from vcpu to user-space thread. My subsequent patch will use this function. Signed-off-by: Bharat Bhushan <bharat.bhushan@freescale.com> Signed-off-by: Stuart Yoder <stuart.yoder@freescale.com>
2013-04-17KVM: PPC: exit to user space on "ehpriv" instructionBharat Bhushan

2013-04-17KVM: extend EMULATE_EXIT_USER to support different exit reasonsBharat Bhushan
Currently the instruction emulator code returns EMULATE_EXIT_USER and common code initializes the "run->exit_reason = .." and "vcpu->arch.hcall_needed = .." with one fixed reason. But there can be different reasons when emulator need to exit to user space. To support that the "run->exit_reason = .." and "vcpu->arch.hcall_needed = .." initialization is moved a level up to emulator.

EMULATE_DO_PAPR reads out to be confusing so it is renamed to EMULATE_EXIT_USER. Signed-off-by: Bharat Bhushan <bharat.bhushan@freescale.com> Signed-off-by: Stuart Yoder <stuart.yoder@freescale.com>
2013-04-17KVM: PPC: debug stub interface parameter definedBharat Bhushan
This patch defines the interface parameter for KVM_SET_GUEST_DEBUG ioctl support. Follow up patches will use this for setting up hardware breakpoints, watchpoints and software breakpoints. Also kvm_arch_vcpu_ioctl_set_guest_debug() is brought one level below. This is because I am not sure what is required for book3s. So this ioctl behaviour will not change for book3s.

2013-04-16powerpc: Replaced tlbilx with tlbwe in the initialization codeDiana Craciun
On Freescale e6500 cores EPCR[DGTMI] controls whether guest supervisor state can execute TLB management instructions. If EPCR[DGTMI]=0 tlbwe and tlbilx are allowed to execute normally in the guest state. A hypervisor may choose to virtualize TLB1 and for this purpose it may use IPROT to protect the entries for being invalidated by the guest. However, because tlbwe and tlbilx execution in the guest state are sharing the same bit, it is not possible to have a scenario where tlbwe is allowed to be executed in guest state and tlbilx traps. When guest TLB management instructions are allowed to be executed in guest state the guest cannot use tlbilx to invalidate TLB1 guest entries. Linux is using tlbilx in the boot code to invalidate the temporary entries it creates when initializing the MMU. The patch is replacing the usage of tlbilx in initialization code with tlbwe with VALID bit cleared. Linux is also using tlbilx in other contexts (like huge pages or indirect entries) but removing the tlbilx from the initialization code offers the possibility to have scenarios under hypervisor which are not using huge pages or indirect entries.

Use device flag IFF_LIVE_ADDR_CHANGE to signal that the device supports changing the hardware address when the device is running. This allows eth_mac_addr() to change the mac address also when the network device's interface is open. This capability is required by certain applications, like bonding mode 6 (Adaptive Load Balancing).

2013-04-16fsl_qman: implement CEETM CCSCI and update some ccg APIsHaiying Wang
The CEETM congestion state change notification uses a seperate bit for CSCN interrupt in software portal's ISR register, and different command to query congestion state. This patch implmentes the CCSCI interrupt handling, and combines the ccg's swp setting into qman_ceetm_ccg_set(), because we can only register ccgr callback to the affine portal.

2013-04-16fsl_qman: use a single CGR list per-portal, not 256Haiying Wang
CGR objects registered against a portal can receive CSCN notifications via that portal, and this supports the existence of there being more than one CGR object for the same CGRID (eg. two distinct drivers using the same portal and using FQs that are subscribed to the same CGR). The portal code was previously using a distinct list of registered CGRs for every possible CGRID, ie. a 256-element array of lists! This meant that when CSCN interrupts occurred and a 256-bit mask was calculated indicating which CGRIDs had changed state, we would iterate that bitmask and for each CGRID that had changed, we would iterate the corresponding list from the array, invoking callbacks for all CGR objects. Now, we just use a singe list for all CGRs, irrespective of CGRID. Rather than iterating the bitmask by CGRID and, for each CGRID that had a state-change, iterating the corresponding CGR list to invoke callbacks, we now just iterate the single CGR list and for each CGR with a callback, we check the bit in the bitmask corresponding to the CGRID to determine whether to invoke the callback. This is a more efficient use of memory (the 256-element array of lists used 2KB per portal on 32-bit cores, 4KB on 64-bit), and the code becomes simpler. And the "downside" doesn't occur, because there are never more than a small handful of CGR objects per portal at most, and quite often only one or two (or even none). So a single list is probably as efficient or even better in the conventional use cases, and much less wasteful of space. Furthermore, this logic will be extended for CEETM CCGRs, of which there are many more than for regular CGRs. So without this change, the extensions for CEETM would continue the previous bad approach, but with 2 or 4 times the unwelcome footprint.

In case of overloading the slaves, the performace will get worse since there are more and more outdated timestamps accumulated in Tx buffer, so we introduce a way to remove those older timestamps between the current matched one and the tail if they are more than TS_ACCUMULATION_THRESHOLD. In addition, we update the buffer size to 256 which is enough according to stress tests.

2013-04-15gianfar: Optimize Tx/Rx ring cleanup with Tx/Rx NAPIClaudiu Manoil
Add a separate NAPI poll routine for Tx cleanup to be triggerred independently by the Tx confirmation interrupts only. Existing poll function is modified to handle only the Rx path processing. The Tx poll routine does not need a budget, since Tx processing doesn't consume NAPI budget, and hence it is registered with minimum NAPI weight. This way the Tx poll routine won't compete for budget with the Rx poll routine. The Rx poll routine is registered with the maximum NAPI weight, just as before. The gfar_configure_coalescing function is simply split in two so that the coalescing timers can be updated separately between the Rx and Tx paths. The schedule cleanup ISR part has been changed to handle the Rx and Tx interrupts independently (since we have separate interrupt lines for Rx and Tx). NAPI scheduling does not require locking since we have different NAPI instances between the Rx and Tx confirmation paths now. This generaly improves the driver's response, most notably when forwading multiple opposite flows.
