…EDIATE The commit 84a1ed5 ("drm/xe/uapi: Remove unused flags") is partially reverted. At the time, flags not used by user space were removed during cleanup. Some flags now needed by the compute runtime are brought back in this commit: - DRM_XE_VM_BIND_FLAG_READONLY is used to write protect kernel ISA thus preventing accidental overwrites. - DRM_XE_VM_BIND_FLAG_IMMEDIATE is used to trigger mapping at the time of binding in order to prevent faulting at execution time. The changes in the compute runtime are ready and approved, see link below. v2: Include a link to the PR in the commit message (Matthew Brost) v3: Update kernel doc and improve commit message (Lucas De Marchi) Cc: Mateusz Jablonski <mateusz.jablonski@intel.com> Cc: Michal Mrozek <michal.mrozek@intel.com> Cc: Matthew Brost <matthew.brost@intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Link: intel/compute-runtime#717 Signed-off-by: Francois Dugast <francois.dugast@intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240329124403.7-1-francois.dugast@intel.com Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>
