ahci: don't enable port irq before handler is registered 2011-05-02T16:19:39+00:00 Maxime Bizon mbizon@freebox.fr 2011-03-16T13:58:32+00:00 068e0202c8c0822c36025198607d1e47d779c86f commit 7b3a24c57d2eeda8dba9c205342b12689c4679f9 upstream. The ahci_pmp_attach() & ahci_pmp_detach() unmask port irqs, but they are also called during port initialization, before ahci host irq handler is registered. On ce4100 platform, this sometimes triggers "irq 4: nobody cared" message when loading driver. Fixed this by not touching the register if the port is in frozen state, and mark all uninitialized port as frozen.

libata: fix hotplug for drivers which don't implement LPM 2011-03-23T20:03:35+00:00 Tejun Heo tj@kernel.org 2011-02-24T18:30:37+00:00 bcefd0d7f34b989c254197bd57c52c848d5ca1cf commit eb0e85e36b971ec31610eda7e3ff5c11c1c44785 upstream. ata_eh_analyze_serror() suppresses hotplug notifications if LPM is being used because LPM generates spurious hotplug events. It compared whether link->lpm_policy was different from ATA_LPM_MAX_POWER to determine whether LPM is enabled; however, this is incorrect as for drivers which don't implement LPM, lpm_policy is always ATA_LPM_UNKNOWN. This disabled hotplug detection for all drivers which don't implement LPM. Fix it by comparing whether lpm_policy is greater than ATA_LPM_MAX_POWER.

libata: set queue DMA alignment to sector size for ATAPI too 2011-01-28T08:16:20+00:00 Tejun Heo htejun@gmail.com 2011-01-20T12:59:06+00:00 729a6a300e628a48cf12bac93a964a535e83cd1d ata_pio_sectors() expects buffer for each sector to be contained in a single page; otherwise, it ends up overrunning the first page. This is achieved by setting queue DMA alignment. If sector_size is smaller than PAGE_SIZE and all buffers are sector_size aligned, buffer for each sector is always contained in a single page. This wasn't applied to ATAPI devices but IDENTIFY_PACKET is executed as ATA_PROT_PIO and thus uses ata_pio_sectors(). Newer versions of udev issue IDENTIFY_PACKET with unaligned buffer triggering the problem and causing oops. This patch fixes the problem by setting sdev->sector_size to ATA_SECT_SIZE on ATATPI devices and always setting DMA alignment to sector_size. While at it, add a warning for the unlikely but still possible scenario where sector_size is larger than PAGE_SIZE, in which case the alignment wouldn't be enough.
