2007-11-03libata: don't configure downstream links faster than the upstream linkTejun Heo
There's nothing to be gained by configuring downstream links faster than the upstream link and such configurations cause problems on certain PMPs. Limit downstream link speed by the upstream link speed. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-11-03libata: request PHY speed configuration on SControl access failureTejun Heo
In sata_set_spd_needed(), if SControl read failed, it returned 0 and skipped PHY speed configuration. However, if SControl access fails, it's far more logical to request PHY speed configuration. Reverse the logic. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-11-03libata: consider errors not associated with commands for speed downTejun Heo
libata EH used to ignore errors not associated with commands when determining whether speed down is necessary or not. This leads to the following problems. * Errors not associated with commands can occur indefinitely without libata EH taking corrective actions. * Upstream link errors don't trigger speed down when PMP is attached to it and commands issued to downstream device trigger errors on the upstream link. This patch makes ata_eh_link_autopsy() consider errors not associated with command for speed down. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-11-03libata: more robust reset failure handlingTejun Heo
Reset failure is a critical error. It results in disabling the link requiring user intervention to re-enable it. Make reset failure handling more robust such that libata EH doesn't give up too early. * Temporary glitches during hardreset may lead to classification failure when there's no softreset available. Retry instead of giving up. * Initial softreset or follow up softreset may fail classification. Move classification error handling block out of followup softreset block such that both cases are handled and retry instead of giving up. Also, on the last try, give ATA class a blind shot.

2007-11-03libata: cosmetic clean up / reorganization of ata_eh_reset()Tejun Heo

2007-11-03libata: fix timing computation in ata_eh_reset()Tejun Heo

2007-11-03libata: increase 128 KB / cmd limit for ATAPI tape drivesTony Battersby
Commands sent to ATAPI tape drives via the SCSI generic (sg) driver are limited in the amount of data that they can transfer by the max_sectors value. The max_sectors value is currently calculated according to the command set for disk drives, which doesn't apply to tape drives. The default max_sectors value of 256 limits ATAPI tape drive commands to 128 KB. This patch against 2.6.24-rc1 increases the max_sectors value for tape drives to 65535, which permits tape drive commands to transfer just under 32 MB. Tested with a SuperMicro PDSME motherboard, AHCI, and a Sony SDX-570V SATA tape drive. Note that some of the chipset drivers also set their own max_sectors value, which may override the value set in libata-core. I don't have any of these chipsets to test, so I didn't go messing with them. Also, ATAPI devices other than tape drives may benefit from similar changes, but I have only tape drives and disk drives to test.

2007-11-03sata_promise: fix endianess bug in ASIC PRD bug workaroundMikael Pettersson
The original workaround for the Promise ASIC PRD bug contained an endianess bug which I failed to detect: the adjustment of the last PRD entry's length field applied host arithmetic to little-endian data, which is incorrect on big-endian machines. We have the length available in host-endian format, so do the adjustment on host-endian data and then convert and store it in the PRD entry's little-endian data field. Thanks to an anonymous reviewer for detecting this bug. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jeff@garzik.org>

Device mapper uses its own bounce_pfn that may differ from one on underlying device.

2007-11-02[SG] Get rid of __sg_mark_end()Jens Axboe
sg_mark_end() overwrites the page_link information, but all users want __sg_mark_end() behaviour where we just set the end bit. That is the most natural way to use the sg list, since you'll fill it in and then mark the end point. So change sg_mark_end() to only set the termination bit.

2007-11-01Input: inport, logibm - use KERN_INFO when reporting missing mouseHelge Deller
Many mouse drivers are often compiled (e.g. in Linux distributions) into the kernel at the same time just to make sure that at least one driver will suceed in find it's mouse device. Nevertheless, only the inport and logitech busmouse mouse drivers report with KERN_ERR log level if the mouse wasn't found.

2007-11-01Fix myri10ge NAPI oops & warningsAndrew Gallatin
When testing the myri10ge driver with 2.6.24-rc1, I found that the machine crashed under heavy load: Unable to handle kernel paging request at 0000000000100108 RIP: [<ffffffff803cc8dd>] net_rx_action+0x11b/0x184 The address corresponds to the list_move_tail() in netif_rx_complete(): if (unlikely(work == weight)) list_move_tail(&n->poll_list, list); Eventually, I traced the crashes to calling netif_rx_complete() with work_done == budget. From looking at other drivers, it appears that one should only call netif_rx_complete() when work_done < budget. To fix it, I changed the test in myri10ge_poll() so that it refers to to work_done rather than looking at the rx ring status. If work_done is < budget, then that implies we have no more packets to process. Any races will be resolved by the NIC when the write to irq_claim is made. In myri10ge_clean_rx_done(), if we ever exceeded our budget, it would report a work_done one larger than was acutally done. This is because the increment was done in the conditional, so work_done would be incremented regardless of whether or not the test passed or failed. This would lead to the WARN_ON_ONCE(work > weight); warning in net_rx_action triggering. I've moved the increment of work_done inside the loop. Note that this would only be a problem when we had exceeded our budget. Signed off by: Andrew Gallatin <gallatin@myri.com> Andrew Gallatin Myricom Inc Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-11-01mpc5200: Fix Kconfig dependancies on MPC5200 FEC device driverGrant Likely
When not building an arch/powerpc kernel, the mpc5200 FEC driver depends on some symbols which are not defined (BESTCOMM & BESTCOMM_FEC). This patch flips around the dependancy logic so that it cannot be selected unless BESTCOMM_FEC is selected first. Kconfig stops complaining this way. Also, the driver only works for arch/powerpc (not arch/ppc) anyway so it should depend on PPC_MERGE also.
