2015-03-16drm/radeon: use drm_mode_vrefresh() rather than mode->vrefreshAlex Deucher1-1/+1
commit 3d2d98ee1af0cf6eebfbd6bff4c17d3601ac1284 upstream. Just in case it hasn't been calculated for the mode. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Jiri Slaby <jslaby@suse.cz>

2014-06-06drm/radeon/pm: don't walk the crtc list before it has been initialized (v2)Alex Deucher1-16/+19
commit 3ed9a335cfc64b2c83545f341cdddf2347b12b97 upstream. Avoids a crash in certain cases when thermal irqs are generated before the display structures have been initialized. v2: fix the vblank and vrefresh helpers as well bug: https://bugzilla.kernel.org/show_bug.cgi?id=73931 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Jiri Slaby <jslaby@suse.cz>

2013-09-11drm/radeon: clean up r600_free_extended_power_table()Dan Carpenter1-24/+14

2013-08-31drm/radeon: gcc fixes for extended dpm tablesAlex Deucher1-24/+50
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.
