2013-08-30drm/radeonn: gcc fixes for rv7xx/eg/btc dpmAlex Deucher
Newer versions of gcc seem to wander off into the weeds when dealing with variable sizes arrays in structs. Rather than indexing the arrays, use pointer arithmetic. See bugs: https://bugs.freedesktop.org/show_bug.cgi?id=66932 https://bugs.freedesktop.org/show_bug.cgi?id=66972 https://bugs.freedesktop.org/show_bug.cgi?id=66945 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-30drm/radeon/dpm: add reclocking quirk for ASUS K70AFAlex Deucher
The LCD has a relatively short vblank time (216us), but the card is able to reclock memory fine in that time. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reported-by: normalrawr@gmail.com
2013-08-07drm/radeon/dpm: fix spread spectrum setup (v2)Alex Deucher
Need to check for engine and memory clock ss separately and only enable dynamic ss if either of them are found. This should fix systems which have a ss table, but do not have entries for engine or memory. On those systems we may enable dynamic spread spectrum without enabling it on the engine or memory clocks which can lead to a hang in some cases. fixes some systems reported here: https://bugs.freedesktop.org/show_bug.cgi?id=66963 v2: fix typo Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-07drm/radeon/dpm: adjust thermal protection requirementsAlex Deucher
On rv770 and newer, clock gating is not required for thermal protection. The only requirement is that the design utilizes a thermal sensor. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-07-17drm/radeon: add a module parameter to disable aspmAlex Deucher
Can cause hangs when enabled in certain motherboards. Set radeon.aspm=0 to disable aspm. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-07-08drm/radeon/dpm: implement vblank_too_short callback for 7xxAlex Deucher
Check if we can switch the mclk during the vblank time otherwise we may get artifacts on the screen when the mclk changes. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-07-08drm/radeon/dpm: fix display_gap programming on rv7xxAlex Deucher
Check the driver state rather than the register as the crtc registers may not be enabled yet. Should fix: https://bugzilla.kernel.org/show_bug.cgi?id=60510 https://bugs.freedesktop.org/show_bug.cgi?id=66651 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
