drm/xe/guc: Add more GuC error codes to ABI

2024-06-26T22:25:07Z

There are many more error codes used that the GuC firmware can return in the RESPONSE_FAILURE message. Add to the ABI header those which are more likely to be seen by the PF or VF drivers.

drm/xe/guc: Drop unused legacy GuC message ABI definitions

Those were copy-pasted from i915 code and never used in Xe driver. Signed-off-by: Michal Wajdeczko Reviewed-by: Nirmoy Das Link: https://patchwork.freedesktop.org/patch/msgid/20240610120411.1768-2-michal.wajdeczko@intel.com

drm/xe/guc: Move H2G SETUP_PC_GUCRC definition to SLPC ABI

2024-06-10T10:41:38Z

We already have a dedicated file for GuC SLPC ABI definitions. Move definition of the SETUP_PC_GUCRC action and related enum to that file, rename them to match format of other new ABI definitions and add simple kernel-doc.

drm/xe/guc: Add GLOBAL_CFG_GMD_ID KLV definition

2024-05-24T08:02:27Z

VF drivers can't access GMD_ID register over MMIO. The value of the GMD_ID register must be queried from GuC. It is available as GLOBAL_CFG_GMD_ID KLV.

drm/xe/guc: Port over the slow GuC loading support from i915

2024-05-23T17:55:31Z

GuC loading can take longer than it is supposed to for various reasons. So add in the code to cope with that and to report it when it happens. There are also many different reasons why GuC loading can fail, so add in the code for checking for those and for reporting issues in a meaningful manner rather than just hitting a timeout and saying 'fail: status = %x'. Also, remove the 'FIXME' comment about an i915 bug that has never been applicable to Xe! v2: Actually report the requested and granted frequencies rather than showing granted twice (review feedback from Badal). v3: Locally code all the timeout and end condition handling because a helper function is not allowed (review feedback from Lucas/Rodrigo). v4: Add more documentation comments and rename a define to add units (review feedback from Lucas). v5: Fix copy/paste error in xe_mmio_wait32_not (review feedback from Lucas) and rebase (no more return value from guc_wait_ucode).
