2014-08-05drm/radeon: Always flush the HDP cache before submitting a CS to the GPUMichel Dänzer7-13/+35
This ensures the GPU sees all previous CPU writes to VRAM, which makes it safe: * For userspace to stream data from CPU to GPU via VRAM instead of GTT * For IBs to be stored in VRAM instead of GTT * For ring buffers to be stored in VRAM instead of GTT, if the HPD flush is performed via MMIO Signed-off-by: Michel Dänzer <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

2014-08-05drm/radeon: use a fetch function to get the edidAlex Deucher7-16/+33
We keep a cached version of the edid in radeon_connector which we use for determining connectedness and when to enable certain features like hdmi audio, etc. When the user uses the firmware interface to override the driver with some other edid the driver's copy is never updated. The fetch function will check if there is a user supplied edid and update the driver's copy if there is. bug: https://bugs.freedesktop.org/show_bug.cgi?id=80691 Signed-off-by: Alex Deucher <[email protected]>

2014-08-05drm/radeon: Inline r100_mm_rreg, -wreg, v3Lauri Kasanen2-37/+36
This was originally un-inlined by Andi Kleen in 2011 citing size concerns. Indeed, a first attempt at inlining it grew radeon.ko by 7%. However, 2% of cpu is spent in this function. Simply inlining it gave 1% more fps in Urban Terror. v2: We know the minimum MMIO size. Adding it to the if allows the compiler to optimize the branch out, improving both performance and size. The v2 patch decreases radeon.ko size by 2%. I didn't re-benchmark, but common sense says perf is now more than 1% better. v3: Also change _wreg, make the threshold a define. Inlining _wreg increased the size a bit compared to v2, so now radeon.ko is only 1% smaller.

2014-08-05drm/radeon: enable display scaling on all connectors (v2)Alex Deucher2-21/+95
This enables the display scaler on all connectors for r5xx and newer asics. Previously we only enabled the scaler for fixed mode displays (eDP or LVDS) since they have to use the scaler to support non-native modes. Most other displays are multi-sync or have a built in scaler to support non-native modes. The default scaling mode for non-fixed displays is none which will use the scaler in the monitor. Note that we do not populate any fake modes like we do for fixed displays so it will only use the modes in the edid. For other modes, you'll need to populate them manually. bug: https://bugs.freedesktop.org/show_bug.cgi?id=80868 v2: properly handle scaling with no modes defined Signed-off-by: Alex Deucher <[email protected]>
