drm/radeon: compute ring fix hibernation (CI GPU family) v2.

2015-08-04T14:52:19Z

commit 161569deaa03cf3c00ed63352006193f250b0648 upstream. In order for hibernation to reliably work we need to cleanup more thoroughly the compute ring. Hibernation is different from suspend resume as when we resume from hibernation the hardware is first fully initialize by regular kernel then freeze callback happens (which correspond to a suspend inside the radeon kernel driver) and turn off each of the block. It turns out we were not cleanly shutting down the compute ring. This patch fix that. Hibernation and suspend to ram were tested (several times) on : Bonaire Hawaii Mullins Kaveri Kabini Changed since v1: - Factor the ring stop logic into a function taking ring as arg.

drm/radeon: partially revert "fix VM_CONTEXT*_PAGE_TABLE_END_ADDR handling"

2015-06-03T09:33:15Z

commit 7c0411d2fabc2e2702c9871ffb603e251158b317 upstream. We have that bug for years and some users report side effects when fixing it on older hardware. So revert it for VM_CONTEXT0_PAGE_TABLE_END_ADDR, but keep it for VM 1-15. Signed-off-by: Christian König Signed-off-by: Alex Deucher Signed-off-by: Jiri Slaby

drm/radeon: make sure mode init is complete in bandwidth_update

2014-11-19T17:38:18Z

commit 8efe82ca908400785253c8f0dfcf301e6bd93488 upstream. The power management code calls into the display code for certain things. If certain power management sysfs attributes are called before the driver has finished initializing all of the hardware we can run into problems with uninitialized modesetting state. Add a check to make sure modesetting init has completed to the bandwidth update callbacks to fix this. Can be triggered by the tlp and laptop start up scripts depending on the timing. bugs: https://bugzilla.kernel.org/show_bug.cgi?id=83611 https://bugs.freedesktop.org/show_bug.cgi?id=85771 Signed-off-by: Alex Deucher Signed-off-by: Jiri Slaby
