Commit a0df2cc858c3 ("drm/xe/xe_bo_move: Enhance xe_bo_move trace") inadvertently reverted commit 8d038f49c1f3 ("drm/xe: Fix cast on trace variable"), breaking the build on 32bits. As noted by Ville, there's no point in converting the pointers to u64 and add casts everywhere. In fact, it's better to just use %p and let the address be hashed.

2024-02-22drm/xe: Prefer struct_size over open coded arithmeticErick Archer1-1/+1
This is an effort to get rid of all multiplications from allocation functions in order to prevent integer overflows [1]. As the "q" variable is a pointer to "struct xe_exec_queue" and this structure ends in a flexible array: struct xe_exec_queue { [...] struct xe_lrc lrc[]; }; the preferred way in the kernel is to use the struct_size() helper to do the arithmetic instead of the argument "size + size * count" in the kzalloc() function. This way, the code is more readable and more safer.

2024-02-21drm/xe: Implement VM snapshot support for BO's and userptrMaarten Lankhorst4-4/+211
Since we cannot immediately capture the BO's and userptr, perform it in 2 stages. The immediate stage takes a reference to each BO and userptr, while a delayed worker captures the contents and then frees the reference. This is required because in signaling context, no locks can be taken, no memory can be allocated, and no waits on userspace can be performed. With the delayed worker, all of this can be performed very easily, without having to resort to hacks. Changes since v1: - Fix crash on NULL captured vm. - Use ascii85_encode to capture BO contents and save some space. - Add length to coredump output for each captured area. Changes since v2: - Dump each mapping on their own line, to simplify tooling. - Fix null pointer deref in xe_vm_snapshot_free. Changes since v3: - Don't add uninitialized value to snap->ofs. (Souza) - Use kernel types for u32 and u64. - Move snap_mutex destruction to final vm destruction. (Souza) Changes since v4: - Remove extra memset.
