2020-11-04drm/ttm: rework no_retry handling v2Christian König1-7/+0
During eviction we do want to trigger the OOM killer. Only while doing new allocations we should try to avoid that and return -ENOMEM to the application. v2: rename the flag to gfp_retry_mayfail.

2020-09-23drm/ttm: stop dangerous caching attribute changeChristian König1-68/+3
When we swapout/in a BO we try to change the caching attributes of the pages before/after doing the copy. On x86 this is done by calling set_pages_uc(), set_memory_wc() or set_pages_wb() for not highmem pages to update the linear mapping of the page. On all other platforms we do exactly nothing. Now on x86 this is unnecessary because copy_highpage() will either create a temporary mapping of the page which is wb anyway and destroyed immediately again or use the linear mapping with the correct caching attributes. So stop this nonsense and just keep the caching as it is and return an error when a driver tries to change the caching of an already populated TT object. This is much more defensive since changing caching attributes is platform and driver specific and usually doesn't work after the page was initially allocated.
