For simulation C models that don't run CP FW where adev->mes.sched_version is not populated correctly. This causes NULL dereference in amdgpu_amdkfd_free_gtt_mem(dev->adev, (void **)&pqn->q->wptr_bo_gart) and warning on unpinned BO in amdgpu_bo_gpu_offset(q->properties.wptr_bo). Compared with adding version check here and there, always map wptr BO to GART simplifies things. v2: Add NULL check in amdgpu_amdkfd_free_gtt_mem.(Philip) Signed-off-by: Lang Yu <lang.yu@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.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.
