Rebinding might allocate page-table bos, causing evictions. To support blocking locking during these evictions, perform the rebinding in the drm_exec locking loop. Also Reserve fence slots where actually needed rather than trying to predict how many fence slots will be needed over a complete wound-wait transaction. v2: - Remove a leftover call to xe_vm_rebind() (Matt Brost) - Add a helper function xe_vm_validate_rebind() (Matt Brost) v3: - Add comments and squash with previous patch (Matt Brost) Fixes:24f947d58f("drm/xe: Use DRM GPUVM helpers for external- and evicted objects") Fixes:29f424eb87("drm/xe/exec: move fence reservation") Cc: Matthew Auld <matthew.auld@intel.com> Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240327091136.3271-5-thomas.hellstrom@linux.intel.com (cherry picked from commit7ee7dd6f30) Signed-off-by: Lucas De Marchi <lucas.demarchi@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 reStructuredText 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.
