| * | [PATCH] PCI: PCIE power management quirkKristen Carlson Accardi2006-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When changing power states from D0->DX and then from DX->D0, some Intel PCIE chipsets will cause a device reset to occur. This will cause problems for any D State other than D3, since any state information that the driver will expect to be present coming from a D1 or D2 state will have been cleared. This patch addes a flag to the pci_dev structure to indicate that devices should not use states D1 or D2, and will set that flag for the affected chipsets. This patch also modifies pci_set_power_state() so that when a device driver tries to set the power state on a device that is downstream from an affected chipset, or on one of the affected devices it only allows state changes to or from D0 & D3. In addition, this patch allows the delay time between D3->D0 to be changed via a quirk. These chipsets also need additional time to change states beyond the normal 10ms.

* | [PATCH] USB: gadget section fixupsDavid Brownell2006-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent section changes broke gadget builds on some platforms. This patch is the best fix that's available until better section markings exist: - There's a lot of cleanup code that gets used in both init and exit paths; stop marking it as "__exit". (Best fix for this would be an "__init_or_exit" section marking, putting the cleanup in __init when __exit sections get discarded else in __exit.) - Stop marking the use-once probe routines as "__init" since references to those routines are not allowed from driver structures. They're now marked "__devinit", which in practice is a net lose. (Best fix for this is likely to separate such use-once probe routines from the driver structure ... but in general, all busses that aren't hotpluggable will be forced to waste memory for all probe-only code.) In general these broken section rules waste an average of two to four kBytes per driver of code bloat ... because none of the relevant code can ever be reused after module initialization.

* [PATCH] md: fix resync speed calculation for restarted resyncsNeilBrown2006-07-10
| | | | | | | | | | | | | | | | | | We introduced 'io_sectors' recently so we could count the sectors that causes io during resync separate from sectors which didn't cause IO - there can be a difference if a bitmap is being used to accelerate resync. However when a speed is reported, we find the number of sectors processed recently by subtracting an oldish io_sectors count from a current 'curr_resync' count. This is wrong because curr_resync counts all sectors, not just io sectors. So, add a field to mddev to store the curren io_sectors separately from curr_resync, and use that in the calculations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reimplement controller-wide PM. ata_host_set_suspend/resume() are defined to suspend and resume a host_set. While suspended, EHs for all ports in the host_set are pegged using ATA_FLAG_SUSPENDED and frozen. Because SCSI device hotplug is done asynchronously against the rest of libata EH and the same mutex is used when adding new device, suspend cannot wait for hotplug to complete. So, if SCSI device hotplug is in progress, suspend fails with -EBUSY. In most cases, host_set resume is followed by device resume. As each resume operation requires a reset, a single host_set-wide resume operation may result in multiple resets. To avoid this, resume waits upto 1 second giving PM to request resume for devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reimplement per-dev PM. The original implementation directly put the device into suspended mode and didn't synchronize w/ EH operations including hotplug. This patch reimplements ata_scsi_device_suspend() and ata_scsi_device_resume() such that they request EH to perform the respective operations. Both functions synchronize with hotplug such that it doesn't operate on detached devices. Suspend waits for completion but resume just issues request and returns. This allows parallel wake up of devices and thus speeds up system resume. Due to sdev detach synchronization, it's not feasible to separate out EH requesting from sdev handling; thus, ata_device_suspend/resume() are removed and everything is implemented in the respective libata-scsi functions.

| * [PATCH] libata: implement PM EH actionsTejun Heo2006-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement two PM per-dev EH actions - ATA_EH_SUSPEND and ATA_EH_RESUME. Each action puts the target device into suspended mode and resumes from it respectively. Once a device is put to suspended mode, no EH operations other than RESUME is allowed on the device. The device will stay suspended till it gets resumed and thus reset and revalidated. To implement this, a new device state helper - ata_dev_ready() - is implemented and used in EH action implementations to make them operate only on attached & running devices. If all possible devices on a port are suspended, reset is skipped too. This prevents spurious events including hotplug events from disrupting suspended devices.

| | | | | | | | | | | | | | | | | | | | Implement ATA_EHI_NO_AUTOPSY and QUIET. These used to be implied by ATA_PFLAG_LOADING, but new power management and PMP support need to use these separately. e.g. Suspend/resume operations shouldn't print full EH messages and resume shouldn't be recorded as an error.

| * [PATCH] libata: clean up debounce parameters and improve parameter selectionTejun Heo2006-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The names of predefined debounce timing parameters didn't exactly match their usages. Rename to more generic names and implement param selection helper sata_ehc_deb_timing() which uses EHI_HOTPLUGGED to select params. Combined with the previous EHI_RESUME_LINK differentiation, this makes parameter selection accurate. e.g. user scan resumes link but normal deb param is used instead of hotplug param.

| * [PATCH] libata: implement ATA_EHI_RESUME_LINKTejun Heo2006-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | Implement ATA_EHI_RESUME_LINK, which indicates that the link needs to be resumed. This used to be implied by ATA_EHI_HOTPLUGGED. However, hotplug isn't the only event which requires link resume and separating this out allows other places to request link resume. This differentiation also allows better debounce timing selection. This patch converts user scan to use ATA_EHI_RESUME_LINK. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
| * [PATCH] libata: add ap->pflags and move core dynamic flags to itTejun Heo2006-07-05
| | | | | | | | | | | | | | | | | | | | ap->flags is way too clamped. Separate out core dynamic flags to ap->pflags. ATA_FLAG_DISABLED is a dynamic flag but left alone as it's referenced by a lot of LLDs and it's gonna be removed once all LLDs are converted to new EH.
