The IS_SRIOV macro returns true also when we are running as a PF driver. Use correct IS_SRIOV_VF macro to skip force-wake management. Fixes: 513ea833 ("drm/xe/vf: Ignore force-wake requests if VF") Signed-off-by:

Add function to set a custom coredump timeout. For Xe driver usage, current 5 minutes timeout may be too short for users to search and understand what needs to be done to capture coredump to report bugs. We have plans to automate(distribute a udev script) it but at the end will be up to distros and users to pack it so having a option to increase the timeout is a safer option. v2: - replace dev_coredump_timeout_set() by dev_coredumpm_timeout() (Mukesh) v3: - make dev_coredumpm() static inline (Johannes) v5: - rename DEVCOREDUMP_TIMEOUT -> DEVCD_TIMEOUT to avoid redefinition in include/net/bluetooth/coredump.h v6: - fix definition of dev_coredumpm_timeout() when CONFIG_DEV_COREDUMP is disabled Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Mukesh Ojha <quic_mojha@quicinc.com> Cc: Johannes Berg <johannes@sipsolutions.net> Cc: Jonathan Cavitt <jonathan.cavitt@intel.com> Reviewed-by:

This WA needs to be applied to graphics GT when the media version is 2000. Currently, media version 2000 is always paired with graphics version 2004 which will result in writing same register with same bits twice. We can't add optional rule in rtp framework and also writing same register with same bits gives warning. Currently, media version 2000 is always paired with graphics version 2004, so just checking the latter is sufficient.
