drm/radeon: fix cut and paste issue for hawaii.

2014-07-31T19:52:57Z

commit 1b2c4869d8247f9e202fa8a73777c34adc62d409 upstream. This is a halfway fix for hawaii acceleration. More fixes to come but hopefully isolated to userspace. Signed-off-by: Jérôme Glisse Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

drm/radeon: fix irq ring buffer overflow handling

2014-07-31T19:52:57Z

commit e8c214d22e76dd0ead38f97f8d2dc09aac70d651 upstream. We must mask out the overflow bit as well, otherwise the wptr will never match the rptr again and the interrupt handler will loop forever.

drm/radeon: avoid leaking edid data

2014-07-28T15:06:02Z

commit 0ac66effe7fcdee55bda6d5d10d3372c95a41920 upstream. In some cases we fetch the edid in the detect() callback in order to determine what sort of monitor is connected. If that happens, don't fetch the edid again in the get_modes() callback or we will leak the edid. Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/qxl: return IRQ_NONE if it was not our irq

2014-07-28T15:06:02Z

commit fbb60fe35ad579b511de8604b06a30b43846473b upstream. Return IRQ_NONE if it was not our irq. This is necessary for the case when qxl is sharing irq line with a device A in a crash kernel. If qxl is initialized before A and A's irq was raised during this gap, returning IRQ_HANDLED in this case will cause this irq to be raised again after EOI since kernel think it was handled but in fact it was not.

drm/radeon: set default bl level to something reasonable

2014-07-28T15:06:02Z

commit 201bb62402e0227375c655446ea04fcd0acf7287 upstream. If the value in the scratch register is 0, set it to the max level. This fixes an issue where the console fb blanking code calls back into the backlight driver on unblank and then sets the backlight level to 0 after the driver has already set the mode and enabled the backlight. bugs: https://bugs.freedesktop.org/show_bug.cgi?id=81382 https://bugs.freedesktop.org/show_bug.cgi?id=70207 Signed-off-by: Alex Deucher Tested-by: David Heidelberger Signed-off-by: Greg Kroah-Hartman

drm/i915: Don't clobber the GTT when it's within stolen memory

2014-07-17T23:21:06Z

commit f1e1c2129b79cfdaf07bca37c5a10569fe021abe upstream. On most gen2-4 platforms the GTT can be (or maybe always is?) inside the stolen memory region. If that's the case, reduce the size of the stolen memory appropriately to make make sure we don't clobber the GTT. v2: Deal with gen4 36 bit physical address Signed-off-by: Ville Syrjälä Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=80151 Acked-by: Chris Wilson Signed-off-by: Daniel Vetter Signed-off-by: Greg Kroah-Hartman

drm/radeon: stop poisoning the GART TLB

2014-07-17T23:21:06Z

commit 0986c1a55ca64b44ee126a2f719a6e9f28cbe0ed upstream. When we set the valid bit on invalid GART entries they are loaded into the TLB when an adjacent entry is loaded. This poisons the TLB with invalid entries which are sometimes not correctly removed on TLB flush. For stable inclusion the patch probably needs to be modified a bit.

drm/radeon: fix typo in golden register setup on evergreen

2014-07-17T23:21:06Z

drm/radeon: fix typo in ci_stop_dpm()

2014-07-17T23:21:06Z

commit ed96377132e564d797c48a5490fd46bed01c4273 upstream. Need to use the RREG32_SMC() accessor since the register is an smc indirect index. Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/radeon/dpm: Reenabling SS on Cayman

2014-07-17T23:21:06Z

commit 41959341ac7e33dd360c7a881d13566f9eca37b2 upstream. It reverts commit c745fe611ca42295c9d91d8e305d27983e9132ef now that Cayman is stable since VDDCI fix. Spread spectrum was not the culprit. This depends on b0880e87c1fd038b84498944f52e52c3e86ebe59 (drm/radeon/dpm: fix vddci setup typo on cayman). Signed-off-by: Alexandre Demers Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman
