Bruce Chang 3e749f5199 drm/i915: Avoid atomic context for error capture ... io_mapping_map_atomic/kmap_atomic are occasionally taken in error capture (if there is no aperture preallocated for the use of error capture), but the error capture and compression routines are now run in normal context: <3> [113.316247] BUG: sleeping function called from invalid context at mm/page_alloc.c:4653 <3> [113.318190] in_atomic(): 1, irqs_disabled(): 0, pid: 678, name: debugfs_test <4> [113.319900] no locks held by debugfs_test/678. <3> [113.321002] Preemption disabled at: <4> [113.321130] [<ffffffffa02506d4>] i915_error_object_create+0x494/0x610 [i915] <4> [113.327259] Call Trace: <4> [113.327871] dump_stack+0x67/0x9b <4> [113.328683] ___might_sleep+0x167/0x250 <4> [113.329618] __alloc_pages_nodemask+0x26b/0x1110 <4> [113.334614] pool_alloc.constprop.19+0x14/0x60 [i915] <4> [113.335951] compress_page+0x7c/0x100 [i915] <4> [113.337110] i915_error_object_create+0x4bd/0x610 [i915] <4> [113.338515] i915_capture_gpu_state+0x384/0x1680 [i915] However, it is not a good idea to run the slow compression inside atomic context, so we choose not to.
