From: Christian König Date: Tue, 8 Dec 2020 15:19:42 +0000 (+0100) Subject: drm/amdgpu: limit the amdgpu_vm_update_ptes trace point X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4932d37055e7a459a92424c4d21ebf8c2c0fb19a;p=linux.git drm/amdgpu: limit the amdgpu_vm_update_ptes trace point The text output should not be more than a page, so only print the first 32 page table entries. If we need all of them we can still look into the binary trace.
