2016-06-13Revert "drm/amdgpu: add pipeline sync while vmid switch in same ctx"Alex Deucher1-3/+1
This reverts commit 2ba272d7bde27e1db2cf1c6cee49b01b7ea08989. The issue fixed by this patch is specific to compute rings and the previous patch was enough. Additionally, this patch as been traced to strange behavior on some CZ systems so we might as well drop it.
2016-06-13amdgpu: fix asic initialization for virtualized environments (v2)Andres Rodriguez1-0/+7
When executing in a PCI passthrough based virtuzliation environemnt, the hypervisor will usually attempt to send a PCIe bus reset signal to the ASIC when the VM reboots. In this scenario, the card is not correctly initialized, but we still consider it to be posted. Therefore, in a passthrough based environemnt we should always post the card to guarantee it is in a good state for driver initialization. However, if we are operating in SR-IOV mode it is up to the GIM driver to manage the asic state, therefore we should not post the card (and shouldn't be able to do it either). v2: add missing semi-colon Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Andres Rodriguez <andres.rodriguez@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2016-06-09drm/amdgpu: add pipeline sync while vmid switch in same ctxChunming Zhou1-1/+3

2016-06-02dma-buf/fence: make fence context 64 bit v2Christian König1-1/+1
Fence contexts are created on the fly (for example) by the GPU scheduler used in the amdgpu driver as a result of an userspace request. Because of this userspace could in theory force a wrap around of the 32bit context number if it doesn't behave well. Avoid this by increasing the context number to 64bits. This way even when userspace manages to allocate a billion contexts per second it takes more than 500 years for the context number to wrap around. v2: fix printf formats as well.

2016-05-13drm/amdgpu: create fence slab once when amdgpu module init.Rex Zhu1-0/+2
This avoids problems with multiple GPUs. For example, if the first GPU failed before amdgpu_fence_init() was called, amdgpu_fence_slab_ref is still 0 and it will get decremented in amdgpu_fence_driver_fini(). This will lead to a crash during init of the second GPU since amdgpu_fence_slab_ref is not 0. v2: add functions for init/exit instead of moving the variables into the driver.
