2009-09-17Input: atkbd - rely on input core to restore state on resumeDmitry Torokhov
Now that input core takes care of restoring state of input devices upon resume we don't need to do anything special here. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

Automatically turn off leds and sound effects as part of suspend process and restore led state, sounds and repeat rate at resume. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2009-09-17Input: libps2 - additional locking for i8042 portsDmitry Torokhov
The serio ports on i8042 are not completely isolated; while we provide enough locking to ensure proper serialization when accessing control and data registers AUX and KBD ports can still have an effect on each other on PS/2 protocol level. The most prominent effect is that issuing a command for the device connected to one port may cause abort of the command currently executing by the device connected to another port. Since i8042 nor serio subsystem are not aware of the details of the PS/2 protocol (length of the commands and their replies and so on) the locking should be done on libps2 level by adding special handling when we see that we are dealing with serio port on i8042.

2009-09-18drm/radeon/kms: move around new init path code to avoid posting at initDave Airlie
We really don't want to post the card at init, it takes a relatively long time and isn't required, so split the resume path into a startup path called by both init/resume and separate resume entry point to do posting. Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-09-18drm: fix drm_fb_helper handling of kernel crtcsJesse Barnes
The drm_fb_helper shouldn't mess with CRTCs that aren't enabled or in its initial config. Ideally it shouldn't even include CRTCs in its initial config if they're not in use, but my old fix for that no longer works. At any rate, this fixes a real bug I was seeing where after a console blank, both pipes would come back on, even though only one had been enabled before that. Since the other pipe had a bogus config, this led to some screen corruption. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-09-17drm/i915: Improve behaviour under memory pressureChris Wilson
Due to the necessity of having to take the struct_mutex, the i915 shrinker can not free the inactive lists if we fail to allocate memory whilst processing a batch buffer, triggering an OOM and an ENOMEM that is reported back to userspace. In order to fare better under such circumstances we need to manually retry a failed allocation after evicting inactive buffers. To do so involves 3 steps: 1. Marking the backing shm pages as NORETRY. 2. Updating the get_pages() callers to evict something on failure and then retry. 3. Revamping the evict something logic to be smarter about the required buffer size and prefer to use volatile or clean inactive pages.

2009-09-17drm/i915: Add ioctl to set 'purgeability' of objectsChris Wilson
Similar to the madvise() concept, the application may wish to mark some data as volatile. That is in the event of memory pressure the kernel is free to discard such buffers safe in the knowledge that the application can recreate them on demand, and is simply using these as a cache.

2009-09-17drm/i915: fix suspend/resume breakage in lid notifierJesse Barnes
We now unconditionally restore the mode at lid open time since some platforms turn off the panel, pipes or other display elements when the lid is closed. There's a problem with doing this at resume time however. At resume time, we'll get a lid event, but restoring the mode at that time may not be safe (e.g. if we get the lid event before global state has been restored), so check the suspended state and make sure our restore is locked against other mode updates.

2009-09-17drm/i915: Add hangcheck timerBen Gamari
We set a periodic timer to check on the GPU, resetting it every time a batch is completed. If the timer elapses, we check acthd. If acthd hasn't changed in two timer periods, we assume the chip is wedged. This is implemented in such a way that it leaves the option open to employ adaptive timer intervals in the future. One could wait until several timer periods have elapsed before declaring the chip dead. If the chip comes back after several periods but before the "dead" threshold, the timer interval or dead threshold could be raised. It is important to note that while checking for active requests, we need to account for the fact that requests are removed from the list (i.e. retired) in a deferred work queue handler. This means that merely checking for an empty request_list is insufficient; the list could be non-empty yet the GPU still idle, causing the hangcheck timer to incorrectly mark the GPU as wedged (it took me a while to figure that out---sigh...)

2009-09-17pata_amd: do not filter out valid modes in nv_mode_filterRobert Hancock
On a Compaq Presario V3000 laptop (NVIDIA MCP51 chipset), pata_amd selects PIO0 mode for the PATA DVD-RAM drive instead of MWDMA2 which it supports: ata4.00: ATAPI: HL-DT-ST DVDRAM GSA-4084N, KQ09, max MWDMA2 ata4: nv_mode_filter: 0x39f&0x7001->0x1, BIOS=0x0 (0x0) ACPI=0x7001 (60:600:0x11) ata4.00: configured for PIO0 For some reason, the BIOS-set UDMA configuration returns 0 and the ACPI _GTM reports that UDMA2 and PIO0 are enabled. This causes nv_mode_filter to end up allowing only PIO0 and UDMA0-2. Since the drive doesn't support UDMA we end up using PIO0. Since the controllers should always support PIO4, MWDMA2 and UDMA2 regardless of what cable type is used, let's make sure we don't filter out these modes regardless of what wacky settings the BIOS is using.

2009-09-17sata_promise: update reset codeMikael Pettersson
sata_promise's reset code has deviated quite a bit from the Promise reference driver's, and it has been observed to fail to recover from errors in some cases. This patch thus updates the reset code to more closely match the reference driver: - soft reset (pdc_reset_port): * wait for ATA engine to not be in packet command mode (2nd gen only) * write reset bit in PDC_CTLSTAT before the first read in the loop * for 2nd gen SATA follow up with FPDMA reset and clearing error status registers - hard reset (pdc_sata_hardreset): * wait for ATA engine to not be in packet command mode (2nd gen only) * reset ATA engine via the PCI control register * Tejun's change to use non-waiting hardreset + follow-up SRST I'm not changing the hotplug mask bits since they are taken care of by sata_promise's ->freeze() and ->thaw() operations. And I'm not writing the PMP port # because that's always zero (for now). Tested here on various controllers. In particular, one disk which used to timeout and fail to recover from certain hdparm and smartmonctl commands now works nicely.
