It is found that i915 will not reset gpu under execlist mode when unload module. that will lead to some issues when unload/load module with different submission mode. e.g. from execlist mode to ring buffer mode via loading/unloading i915. Because HW is not in a reset state and registers are not clean under such condition. Signed-off-by:

In this WA we need to set GEN8_L3SQCREG4[21:21] and reset it after PIPE_CONTROL instruction but there is a slight complication as this is applied in WA batch where the values are only initialized once. Dave identified an issue with the current implementation where the register value is read once at the beginning and it is reused; this patch corrects this by saving the register value to memory, update register with the bit of our interest and restore it back with original value. This implementation uses MI_LOAD_REGISTER_MEM which is currently only used by command parser and was using a default length of 0. This is now updated with correct length and moved to appropriate place. Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Dave Gordon <david.s.gordon@intel.com> Signed-off-by:

Which should protect dev_priv->mm.stolen usage. This will allow us to simplify the relationship between stolen memory, FBC and struct_mutex. v2: - Rebase after the stolen_remove_node() dev_priv patch move. - I realized that after we fixed a few things related to the FBC CFB size checks, we're not reallocating the CFB anymore with FBC enabled, so we can just move all the locking to i915_gem_stolen.c and stop worrying about freezing all the stolen alocations while freeing/rellocating the CFB. This allows us to fix the "Too coarse" observation from Chris. Suggested-by: -

With the abstractions created by the last patch, we can move this code and the only thing inside intel_fbc.c that knows about dev_priv->mm is the code that reads stolen_base.

We want to move the FBC code out of i915_gem_stolen.c, but that code directly adds/removes stolen memory nodes. Let's create this abstraction, so i915_gme_stolen.c is still in control of all the stolen memory handling. The abstraction will also allow us to add locking assertions later. v2: - Add dev_priv as remove_node() argument since we'll need it later (Chris). Requested-by: -

CHV/BXT DPLL can't generate frequencies in the 216-240 MHz range. Account for that when checking whether the HDMI port clock is valid. This is particularly important for BXT since it can otherwise do 12bpc, and standard 1920x1080p60 CEA modes land right in the middle of that range when the clock gets multiplied to account for 12bpc. With the extra checks we will now filter out any mode where both 8bpc and 12bpc clock are within the gap. During modeset we then pick whichever mode works, favoring 12bpc if both are possible. 12bpc isn't supported on CHV so we simply end up filtering out any mode where the 8bpc port clock is in the gap. v2: Fix crtc_clock vs. port_clock fumble in compute_config() (Imre) Signed-off-by:

We first set the threshold value when we're allocating the CFB, and then later at {ilk,gen7}_fbc_enable() we increment it in case we're using 16bpp. While that is correct, it is dangerous: if we rework the code a little bit in a way that allows us to call intel_fbc_enable() without necessarily calling i915_gem_stolen_setup_compression() first, we might end up incrementing threshold more than once. To prevent that, increment a temporary variable instead. v2: Rebase. Signed-off-by: -

An earlier patch was added to reserve space in the ring buffer for the commands issued during 'add_request()'. The initial version was pessimistic in the way it handled buffer wrapping and would cause premature wraps and thus waste ring space. This patch updates the code to better handle the wrap case. It no longer enforces that the space being asked for and the reserved space are a single contiguous block. Instead, it allows the reserve to be on the far end of a wrap operation. It still guarantees that the space is available so when the wrap occurs, no wait will happen. Thus the wrap cannot fail which is the whole point of the exercise. Also fixed a merge failure with some comments from the original patch. v2: Incorporated suggestion by David Gordon to move the wrap code inside the prepare function and thus allow a single combined wait_for_space() call rather than doing one before the wrap and another after. This also makes the prepare code much simpler and easier to follow. v3: Fix for 'effective_size' vs 'size' during ring buffer remainder calculations (spotted by Tomas Elf).
