Discussion was continuing after patch application, trying to figure out how to best mesh exported data with the installers, boot-time agents and other parties that want this info. 2) Merge Zero-Power Optical Device Driver (ZPODD) support, bringing the wonderfulness of sane power management to your CD/DVD device. Includes one SCSI-subsystem patch (with appropriate ACKs), adding runtime PM support to 'sr' driver. That is the ZPODD interaction bits. Patchset went through some 13 revisions before it got here; kudos to Intel for persistence. 3) pata_samsung_cf: use devm_clk_get() 4) more ata_piix, ahci PCI IDs 5) Add SATA driver for R-Car SoC 6) Convert libata to use devm_ioremap_resource (Note: I think Greg sent this to you, also) 7) Set proper Sense Key (SK) in the SCSI simulator when ATA passthrough indicates check condition. Google and specification hawks everywhere shall rejoice. * tag 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev: (22 commits) [libata] fix smatch warning for zpodd_wake_dev [libata] Set proper SK when CK_COND is set.

| * [libata] fix smatch warning for zpodd_wake_devAaron Lu2013-02-201-2/+1Star
| | | | | | | | | | | | | | | | | | | | Fix a smatch warning caused by an useless pointer check. The context parameter (aka. ata_dev) will never be NULL until we remove the acpi notification handler, so it is pointless to check it for NULL.

| * [libata] scsi: no poll when ODD is powered offAaron Lu2013-01-251-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the ODD is powered off, any action the user did to the ODD that would generate a media event will trigger an ACPI interrupt, so the poll for media event is no longer necessary. And the poll will also cause a runtime status change, which will stop the ODD from staying in powered off state, so the poll should better be stopped. But since we don't have access to the gendisk structure in LLDs, here comes the disk_events_disable_depth for scsi device. This field is a hint set by LLDs to convey information to upper layer drivers. A value of 0 means media poll is necessary for the device, while values above 0 means media poll is not needed and should better be skipped. So we can increase its value when we are to power off the ODD in ATA layer and decrease its value when the ODD is powered on, effectively silence the media events poll.

| * [libata] PM code cleanup for ata portAaron Lu2013-01-251-12/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For system freeze, if the port is already runtime suspended, leave it alone and just return. The port will be resumed on thaw before it will be used. And since we will call get_noresume for every device during prepare phase, and the port is resumed during thaw phase, it can't be in runtime suspended state during the poweroff phase. So remove the runtime_suspended check in poweroff callback. And for all suspend(freeze/suspend/poweroff/etc.), there is no need to touch the device, so set no_autopsy and no_recovery for them all.

| * [libata] pm: differentiate system and runtime pm for ata portAaron Lu2013-01-253-39/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to do different things for system PM and runtime PM, e.g. we do not need to enable runtime wake for ZPODD when we are doing system suspend, etc. Currently, we use PMSG_SUSPEND for both system suspend and runtime suspend and PMSG_ON for both system resume and runtime resume. Change this by using PMSG_AUTO_SUSPEND for runtime suspend and PMSG_AUTO_RESUME for runtime resume. And since PMSG_ON means no transition, it is changed to PMSG_RESUME for ata port's system resume. The ata_acpi_set_state is modified accordingly, and the sata case and pata case is seperated for easy reading.

| * libata: do not suspend port if normal ODD is attachedAaron Lu2013-01-211-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For ODDs, the upper layer will poll for media change every few seconds, which will make it enter and leave suspend state very often. And as each suspend will also cause a hard/soft reset, the gain of runtime suspend is very little while the ODD may malfunction after constantly being reset. So the idle callback here will not proceed to suspend if a non-ZPODD capable ODD is attached to the port.

| * libata: expose pm qos flags for ata deviceAaron Lu2013-01-212-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Expose pm qos flags to user space so that user has a chance to disable ZPODD feature, if he/she has a broken platform or devices or simply does not like this feature. This flag is exposed to user space only for ZPODD devices. Due to this flag, it is possible the ODD is ZP ready but we didn't power it off. So the zp_ready flag will need to be cleared whenever we found the ODD is not in ZP ready state. Previously, once zp_ready is set, the ODD will always be powered off and the flag will be cleared in post_poweron. But this is no longer the case now.

| * libata: handle power transition of ODDAaron Lu2013-01-214-10/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When ata port is runtime suspended, it will check if the ODD attched to it is a zero power(ZP) capable ODD and if the ZP capable ODD is in zero power ready state. And if this is not the case, the highest acpi state will be limited to ACPI_STATE_D3_HOT to avoid powering off the ODD. And if the ODD can be powered off, runtime wake capability needs to be enabled and powered_off flag will be set to let resume code knows that the ODD was in powered off state. And on resume, before it is powered on, if it was powered off during suspend, runtime wake capability needs to be disabled. After it is recovered, the ODD is considered functional, post power on processing like eject tray if the ODD is drawer type is done, and several ZPODD related fields will also be reset.

| * libata: check zero power ready status for ZPODDAaron Lu2013-01-213-2/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Per the Mount Fuji spec, the ODD is considered zero power ready when: - For slot type ODD, no media inside; - For tray type ODD, no media inside and tray closed. The information can be retrieved by either the returned information of command GET_EVENT_STATUS_NOTIFICATION(the command is used to poll for media event) or sense code. The information provided by the media status byte is not accurate, it is possible that after a new disc is just inserted, the status byte still returns media not present. So this information can not be used as the deciding factor, we use sense code to decide if zpready status is true. When we first sensed the ODD in the zero power ready state, the zp_sampled will be set and timestamp will be recoreded. And after ODD stayed in this state for some pre-defined period, the ODD is considered as power off ready and the zp_ready flag will be set. The zp_ready flag serves as the deciding factor other code will use to see if power off is OK for the ODD. The Mount Fuji spec suggests a delay should be used here, to avoid the case user ejects the ODD and then instantly inserts a new one again, so that we can avoid a power transition. And some ODDs may be slow to place its head to the home position after disc is ejected, so a delay here is generally a good idea. And the delay time can be changed via the module param zpodd_poweroff_delay. The zero power ready status check is performed in the ata port's runtime suspend code path, when port is not frozen yet, as we need to issue some IOs to the ODD.

| * libata: move acpi notification code to zpoddAaron Lu2013-01-212-71/+34Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the ata acpi notification code introduced in commit 3bd46600a7a7e938c54df8cdbac9910668c7dfb0 is solely for ZPODD, and we now have a dedicated place for it, move these code there. And the ata_acpi_add_pm_notifier code is changed a little bit in that it is now invoked when scsi device is not bound with ACPI yet, so the way to get the acpi handle is different with the previous version. And the ata_acpi_add/remove_pm_notifier is also simplified a little bit in that it doesn't check if the acpi_device for the handle exists or not as the odd_can_poweroff function already checked that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ODD can be enabled for ZPODD if the following three conditions are satisfied: 1 The ODD supports device attention; 2 The platform can runtime power off the ODD through ACPI; 3 The ODD is either slot type or drawer type. For such ODDs, zpodd_init is called and a new structure is allocated for it to store ZPODD related stuffs. And the zpodd_dev_enabled function is used to test if ZPODD is currently enabled for this ODD. A new config CONFIG_SATA_ZPODD is added to selectively build ZPODD code.

It has a few interesting highlights, in addition to the usual bunch of bug fixes, minor updates, embedded device tree updates and new boards: - Hand tuned asm implementation of SHA1 (by Paulus & Michael Ellerman) - Support for Doorbell interrupts on Power8 (kind of fast thread-thread IPIs) by Ian Munsie - Long overdue cleanup of the way we handle relocation of our open firmware trampoline (prom_init.c) on 64-bit by Anton Blanchard - Support for saving/restoring & context switching the PPR (Processor Priority Register) on server processors that support it. This allows the kernel to preserve thread priorities established by userspace. By Haren Myneni. - DAWR (new watchpoint facility) support on Power8 by Michael Neuling - Ability to change the DSCR (Data Stream Control Register) which controls cache prefetching on a running process via ptrace by Alexey Kardashevskiy - Support for context switching the TAR register on Power8 (new branch target register meant to be used by some new specific userspace perf event interrupt facility which is yet to be enabled) by Ian Munsie. - Improve preservation of the CFAR register (which captures the origin of a branch) on various exception conditions by Paulus. - Move the Bestcomm DMA driver from arch powerpc to drivers/dma where it belongs by Philippe De Muyter - Support for Transactional Memory on Power8 by Michael Neuling (based on original work by Matt Evans).

Don't keep the driver hidden in arch/powerpc where it is inaccessible for other arches. .c files are moved to drivers/dma/bestcomm, while .h files are moved to include/linux/fsl/bestcomm.

Unfortunately, however, this was a mistake, because all devices depending on power resources should be treated this way (i.e. they should be resumed when all power resources required by their D0 state have been turned on) and for the majority of those devices the ACPI core can figure out by itself which (physical) devices depend on what power resources. For this reason, replace the code added by commit 0090def6 with a new, much more straightforward, mechanism that will be used internally by the ACPI core and remove all references to that code from kernel subsystems using ACPI. For the cases when there are (physical) devices that should be resumed whenever a not directly related ACPI device node goes into D0 as a result of power resources configuration changes, like in the SATA case, add two new routines, acpi_dev_pm_add_dependent() and acpi_dev_pm_remove_dependent(), allowing subsystems to manage such dependencies. Convert the SATA subsystem to use the new functions accordingly. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

As result, interrupts generated by different ports could be serviced on different CPUs rather than on a single one. In cases when number of allocated MSIs is less than requested the Sharing Last MSI mode does not get used, no matter implemented in hardware or not. Instead, the driver assumes the advantage of multiple MSIs is negated and falls back to the single MSI mode as if MRSM bit was set (some Intel chips implement this strategy anyway - MRSM bit gets set even if the number of allocated MSIs exceeds the number of implemented ports).

| | | | | | | | | | | | | | | | | | These structs are used only for ahci_platform.c, so they should be static. Thanks to Fengguang for the (automated) suggestion.

I was mostly converting a few other drivers which used some simple, common patterns to use my new common code, but this driver was missing it altogether. It looks like there may be bigger issues, though, as you point out. > This patch is likely to be incomplete as the driver is also missing the > module_exit() things. > > It might be simpler to just make the driver "bool" instead of "tristate" in > the Kconfig. As noted earlier, I don't have much interest in this driver. I agree that there are some other issues with the driver; I think it leaks memory if it is ever allowed to unload, for one. Feel free to submit an alternative patch to prevent this driver from being built as a module. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | This driver does not detach and remove its ata_host properly on device removal. Add the common .remove helper. Note: I do not know this driver well enough to ensure this is the right thing to do. Merge this patch with caution.
