* drm/radeon: Replace ttm_bo_unref with ttm_bo_putThomas Zimmermann2018-07-311-3/+2
| | | | | | | | | | | | | | | | | | The function ttm_bo_put releases a reference to a TTM buffer object. The function's name is more aligned to the Linux kernel convention of naming ref-counting function _get and _put. A call to ttm_bo_unref takes the address of the TTM BO object's pointer and clears the pointer's value to NULL. This is not necessary in most cases and sometimes even worked around by the calling code. A call to ttm_bo_put only releases the reference without clearing the pointer. The current behaviour of cleaning the pointer is kept in the calling code, but should be removed if not required in a later patch.

* radeon: hide pointless #warning when compile testingArnd Bergmann2018-02-261-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | In randconfig testing, we sometimes get this warning: drivers/gpu/drm/radeon/radeon_object.c: In function 'radeon_bo_create': drivers/gpu/drm/radeon/radeon_object.c:242:2: error: #warning Please enable CONFIG_MTRR and CONFIG_X86_PAT for better performance thanks to write-combining [-Werror=cpp] #warning Please enable CONFIG_MTRR and CONFIG_X86_PAT for better performance \ This is rather annoying since almost all other code produces no build-time output unless we have found a real bug. We already fixed this in the amdgpu driver in commit 31bb90f1cd08 ("drm/amdgpu: shut up #warning for compile testing") by adding a CONFIG_COMPILE_TEST check last year and agreed to do the same here, but both Michel and I then forgot about it until I came across the issue again now. For stable kernels, as this is one of very few remaining randconfig warnings in 4.14.

* drm/radeon: drop ttm two ended allocationAlex Deucher2015-03-181-11/+0
| | | | | | | | | | | | | | | | | | | | radeon_bo_create() calls radeon_ttm_placement_from_domain() before ttm_bo_init() is called. radeon_ttm_placement_from_domain() uses the ttm bo size to determine when to select top down allocation but since the ttm bo is not initialized yet the check is always false. It only took effect when buffers were validated later. It also seemed to regress suspend and resume on some systems possibly due to it not taking effect in radeon_bo_create(). radeon_bo_create() and radeon_ttm_placement_from_domain() need to be reworked substantially for this to be optimally effective. Re-enable it at that point.
