2011-06-23drm/nvc0/gr: import and use our own fuc by defaultBen Skeggs
The ability to use NVIDIA's fuc has been retained *temporarily* in order to better debug any issues that may be lingering in our initial attempt at writing this ucode. Once I'm fairly confident we're okay, it'll be removed. There's a number of things not implemented by this fuc currently, but most of it is sets of state that our context setup would not have used anyway. No doubt we'll find out what they're for at some point, and implement it if required. This has been tested on 0xc0/0xc4 thus far, and from what I could tell it worked as well as NVIDIA's. It's also been tested on 0xc1, but even with NVIDIA's fuc that chipset doesn't work correctly with nouveau yet. 0xc3/0xc8/0xce should in theory be supported too, but I don't have the hardware to check that. There's no doubt numerous bugs to squash yet, please report any! Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-06-23drm/nvc0: fix suspend/resume of PGRAPH/PCOPYnBen Skeggs
We need the physical VRAM address in vinst, even for objects mapped into a vm, as the gpuobj suspend/resume code uses PMEM to access the object. Previously, vinst was overloaded to mean "VRAM address" for !VM objects, and "VM address" for VM objects, causing the wrong data to be accessed during suspend/resume.

2011-06-23drm/nouveau: default to noaccel on 0xc1/0xc8/0xce for nowBen Skeggs
Until we know these should work properly, would much rather default to noaccel than risk giving people corruption/hangs out of the box.. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-06-23drm/nvc1/gr: switch on acceleration supportBen Skeggs

2011-06-20drm/radeon: avoid warnings from r600/eg irq handlers on powered off card.Dave Airlie
Since we were calling the wptr function before checking if the IH was even enabled, or the GPU wasn't shutdown, we'd get spam in the logs when the GPU readback 0xffffffff. This reorders things so we return early in the no IH and GPU shutdown cases.

2011-06-20drm/radeon/kms/atom: fix duallink on some early DCE3.2 cardsAlex Deucher
Certain revisions of the vbios on DCE3.2 cards have a bug in the transmitter control table which prevents duallink from being enabled properly on some cards. The action switch statement jumps to the wrong offset for the OUTPUT_ENABLE action. The fix is to use the ENABLE action rather than the OUTPUT_ENABLE action on the affected cards. In fixed version of the vbios, both actions jump to the same offset, so the change should be safe.

While parsing the perf table, there is no check if the num of entries read from the vbios is less than the currently allocated number.

2011-06-18drm/i915: Fix gen6 (SNB) missed BLT ring interrupts.Daniel J Blueman
The failure appeared in dmesg as: [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle [waiting on 35064155, at 35064155], missed IRQ? This works around that problem on by making the blitter command streamer write interrupt state to the Hardware Status Page when a MI_USER_INTERRUPT command is decoded, which appears to force the seqno out to memory before the interrupt happens. v1->v2: Moved to prior interrupt handler installation and RMW flags as per feedback. v2->v3: Removed RMW of flags (by anholt) Cc: stable@kernel.org Signed-off-by: Daniel J Blueman <daniel.blueman@gmail.com> Signed-off-by: Eric Anholt <eric@anholt.net> Tested-by: Chris Wilson <chris@chris-wilson.co.uk> [v1] Tested-by: Eric Anholt <eric@anholt.net> [v1,v3] (incidence of the bug with a testcase went from avg 2/1000 to 0/12651 in the latest test run (plus more for v1)) Tested-by: Kenneth Graunke <kenneth@whitecape.org> [v1] Tested-by: Robert Hooker <robert.hooker@canonical.com> [v1] Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=33394 Signed-off-by: Dave Airlie <airlied@redhat.com>

2011-06-16drm/radeon: workaround a hw bug on some radeon chipsets with all-0 EDIDs.Dave Airlie
Some RS690 chipsets seem to end up with floating connectors, either a DVI connector isn't actually populated, or an add-in HDMI card is available but not installed. In this case we seem to get a NULL byte response for each byte of the i2c transaction, so we detect this case and if we see it we don't do anymore DDC transactions on this connector. I've tested this on my RS690 without the HDMI card installed and it seems to work fine. Signed-off-by: Dave Airlie <airlied@redhat.com> Reviewed-by: Alex Deucher <alexdeucher@gmail.com>
