drm/i915/selftests: Add tests for GT and engine workaround verification

2018-12-04T12:23:19Z

Two simple selftests which test that both GT and engine workarounds are not lost after either a full GPU reset, or after the per-engine ones. (Including checks that one engine reset is not affecting workarounds not belonging to itself.) v2: * Rebase for series refactoring. * Add spinner for actual engine reset! * Add idle reset test as well. (Chris Wilson) * Share existing global_reset_lock. (Chris Wilson) v3: * intel_engine_verify_workarounds can be static. * API rename. (Chris Wilson) * Move global reset lock out of the loop. (Chris Wilson) v4: * Add missing rpm puts.

drm/i915/dsc: Define & Compute VESA DSC params

2018-11-29T20:22:14Z

This patches does the following: 1. This patch defines all the DSC parameters as per the VESA DSC specification. These are stored in the encoder and used to compute the PPS parameters to be sent to the Sink. 2. Compute all the DSC parameters which are derived from DSC state of intel_crtc_state. 3. Compute all parameters that are VESA DSC specific This computation happens in the atomic check phase during compute_config() to validate if display stream compression can be enabled for the requested mode. v8 (From Manasi): * DEBUG_KMS instead of DRM_ERROR for user triggerable errors (Ville) v7: (From Manasi) * Dont use signed int for rc_range_params (Manasi) * Mask the range_bpg_offset to use only 6 bits * Add SPDX identifier (Chris Wilson) v6 (From Manasi): * Add a check for line_buf_depth return value (Anusha) * Remove DRM DSC constants to different patch (Manasi) v5 (From Manasi): * Add logic to limit the max line buf depth for DSC 1.1 to 13 as per DSC 1.1 spec * Fix dim checkpatch warnings/checks v4 (From Gaurav): * Rebase on latest drm tip * rename variable name(Manasi) * Populate linebuf_depth variable(Manasi) v3 (From Gaurav): * Rebase my previous patches on top of Manasi's latest patch series * Using >>n rather than /2^n (Manasi) * Change the commit message to explain what the patch is doing(Gaurav) Fixed review comments from Ville: * Don't use macro TWOS_COMPLEMENT * Mention in comment about the source of RC params * Return directly from case statements * Using single asssignment for assigning rc_range_params * Using < Cc: Ville Syrjala Cc: Anusha Srivatsa Cc: Gaurav K Singh Signed-off-by: Gaurav K Singh Signed-off-by: Manasi Navare Co-developed-by: Manasi Navare Reviewed-by: Anusha Srivatsa Link: https://patchwork.freedesktop.org/patch/msgid/20181129193827.7914-1-manasi.d.navare@intel.com

drm/i915/cnl+: Move the combo PHY init/uninit code to a new file

2018-11-08T17:27:00Z

Similarly to the GEN9_LP DPIO PHY code keep the CNL+ combo PHY code in a separate file. No functional change. v2: - Use SPDX license tag instead of boilerplate.

Makefile: Globally enable VLA warning

Now that Variable Length Arrays (VLAs) have been entirely removed[1] from the kernel, enable the VLA warning globally. The only exceptions to this are the KASan an UBSan tests which are explicitly checking that VLAs trigger their respective tests.

drm/i915: Pull scheduling under standalone lock

2018-10-01T19:34:21Z

Currently, the backend scheduling code abuses struct_mutex into order to have a global lock to manipulate a temporary list (without widespread allocation) and to protect against list modifications. This is an extraneous coupling to struct_mutex and further can not extend beyond the local device. Pull all the code that needs to be under the one true lock into i915_scheduler.c, and make it so.
