From: James Zhu Date: Fri, 8 Dec 2023 22:41:25 +0000 (-0500) Subject: drm/amdgpu: increase hmm range get pages timeout X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=78b4dfd35999e22b4f589a3e070c4aa5f07ce3a2;p=linux.git drm/amdgpu: increase hmm range get pages timeout When application tries to allocate all system memory and cause memory to swap out. Needs more time for hmm_range_fault to validate the remaining page for allocation. To be safe, increase timeout value to 1 second for 64MB range.
