2005-08-30[libata] allow ATAPI to be enabled with new atapi_enabled module optionJeff Garzik
ATAPI is getting close to being ready. To increase exposure, we enable the code in the upstream kernel, but default it to off (present behavior). Users must pass atapi_enabled=1 as a module option (if module) or on the kernel command line (if built in) to turn on discovery of their ATAPI devices.

2005-08-27[PATCH] sg.c: fix a memory leak in devices seq_file implementationJan Blunck
I know that scsi procfs is legacy code but this is a fix for a memory leak. While reading through sg.c I realized that the implementation of /proc/scsi/sg/devices with seq_file is leaking memory due to freeing the pointer returned by the next() iterator method. Since next() might return NULL or an error this is wrong. This patch fixes it through using the seq_files private field for holding the reference to the iterator object. Here is a small bash script to trigger the leak. Use slabtop to watch the size-32 usage grow and grow. #!/bin/sh while true; do cat /proc/scsi/sg/devices > /dev/null done Signed-off-by: Jan Blunck <j.blunck@tu-harburg.de> Acked-by: James Bottomley <James.Bottomley@steeleye.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-08-23[PATCH] sil: apply M15W quirk selectively (take 2)Tejun Heo
As SII reports that only original 3112's are affected by M15W quirk, This patch adds SIL_FLAG_MOD15WRITE to selectively apply M15W quirk depending on chipsets. As of yet, we don't know exactly which PCI IDs are for original 3112, so M15W quirk is applied to all except for 3512 and 3124. Once more info is avaliable, we can change some of these sil_3112_m15w's to sil_3112. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-08-23[PATCH] libata: implement ata_poll_qc_complete and use it in polling functionsTejun Heo
[PATCH libata-dev-2.6:upstream] implement ata_poll_qc_complete and use it in polling functions Previously, libata polling functions turned irq back on and completed qc commands without holding host lock. This creates a race condition between the polling task and interrupts from other ports on the same host set or spurious interrupt from itself. This patch implements ata_poll_qc_complete which enables irq and completes qc atomically and convert all polling functions. Note: atapi_packet_task() didn't use to turn irq back on or clear ATA_FLAG_NOINTR on error exits. This patch makes it use ata_poll_qc_complete which does both. Note: With this change, ALL invocations of ata_qc_complete() are now done under host_set lock. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-08-23[PATCH] fix atapi_packet_task vs. intr race (take 2)Tejun Heo
Interrupts from devices sharing the same IRQ could cause ata_host_intr to finish commands being processed by atapi_packet_task if the commands are using ATA_PROT_ATAPI_NODATA or ATA_PROT_ATAPI_DMA protocol. This is because libata interrupt handler is unaware that interrupts are not expected during that period. This patch adds ATA_FLAG_NOINTR flag to tell the interrupt handler that we're not expecting interrupts. Note that once proper HSM is implemented for interrupt-driven PIO, this should be merged into it and this flag will be removed. ahci.c is a different kind of beast, so it's left alone. * The following drivers use ata_qc_issue_prot and ata_interrupt, so changes in libata core will do. ata_piix sata_sil sata_svw sata_via sata_sis sata_uli * The following drivers use ata_qc_issue_prot and custom intr handler. They need this change to work correctly. sata_nv sata_vsc * The following drivers use custom issue function and intr handler. Currently all custom issue functions don't support ATAPI, so this change is irrelevant, updated for consistency and to avoid later mistakes. sata_promise sata_qstor sata_sx4 Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2005-08-23[PATCH] Fix HD activity LED with ahciMartin Wilck
Patch: fix wrong HD activity control by ahci driver The ahci driver 1.0 sets the SActive bit on every transaction, causing the LED to light up. The SActive bit is used only for native command queuing (NCQ) which the current driver version doesn't implement. Resetting the SActive bit is the device's responsibility (by sending a "Set Device Bits FIS" to the host adapter) but this is not required in response to non-NCQ commands, and (most) devices don't. Thus the LED stays always on. This patch fixes the LED behavior.
