UAPI Changes: - Create gt/gtN/.defaults/ for per gt sysfs defaults Create a gt/gtN/.defaults/ directory (similar to engine/<engine-name>/.defaults/) to expose default parameter values for each gt in sysfs. This allows userspace to restore default parameter values after they have changed. Driver Changes: - Support GuC v69 in parallel to v70 (Daniele) - Improve TLB invalidation to limit performance regression (Chris, Mauro) - Expose per-gt RPS defaults in sysfs (Ashutosh) - Suppress OOM warning for shmemfs object allocation failure (Chris, Nirmoy) - Disable PCI resize on 32-bit machines (Nirmoy) - Update DG2 to GuC v70.4.1 (John) - Fix CCS data copying on DG2 during swapping (Matt A) - Add DG2 performance tuning setting recommended by spec (Matt R) - Add GuC <-> kernel time stamp translation information to error logs (John) - Record GuC CTB info in error logs (John) - Route semaphores to GuC for Gen12+ when enabled (Michal Wi, John) - Improve resilency to bug #3575: Handle reset timeouts under unrelated kernel hangs (Chris, Ashutosh) - Avoid system freeze by removing shared locking on freeing objects (Chris, Nirmoy) - Demote GuC error "No response for request" into debug when expected (Zhanjun) - Fix GuC capture size warning and bump the size (John) - Use streaming loads to speed up dumping the GuC log (Chris, John) - Don't abort on CTB_UNUSED status from GuC (John) - Don't send spurious policy update for GuC child contexts (Daniele) - Don't leak the CCS state (Matt A) - Prefer drm_err over pr_err (John) - Eliminate unused calc_ctrl_surf_instr_size (Matt A) - Add dedicated function for non-ctx register tuning settings (Matt R) - Style and typo fixes, documentation improvements (Jason Wang, Mauro) - Selftest improvements (Matt B, Rahul, John) Signed-off-by: Dave Airlie <airlied@redhat.com> From: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/YwYTCjA/Rhpd1n4A@jlahtine-mobl.ger.corp.intel.com
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
