1This directory contains a copy of the installed kernel headers 2required by the iHD driver to communicate with the kernel. 3Whenever driver needs new definitions for new kernel 4APIs, these files should be updated. 5 6These files in master should only be updated once the changes have landed 7in the drm-xe-next tree (see https://gitlab.freedesktop.org/drm/xe/kernel.git). 8 9You can copy files installed after running this from the kernel 10repository, at version the driver require: 11 12$ make headers_install INSTALL_HDR_PATH=/path/to/install 13 14The last update was done at the following kernel commit: 15 16commit b2121f2bd2232cd0556b2182078d159d81497885 (HEAD -> drm-xe-next, origin/drm-xe-next) 17 18drm/xe: Extend uAPI to query HuC micro-controler firmware version 19 20The infrastructure to query GuC firmware version is already in place. It 21is extended with a new micro-controller type to query the HuC firmware 22version. It can be used from user space to know if HuC is running. 23 24Cc: John Harrison <John.C.Harrison@Intel.com> 25Cc: Francois Dugast <francois.dugast@intel.com> 26Cc: Lucas De Marchi <lucas.demarchi@intel.com> 27Signed-off-by: Francois Dugast <francois.dugast@intel.com> 28Signed-off-by: José Roberto de Souza <jose.souza@intel.com> 29Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> 30Reviewed-by: John Harrison <John.C.Harrison@Intel.com> 31Link: https://patchwork.freedesktop.org/patch/msgid/20240208183539.185095-2-jose.souza@intel.com 32
