We need to wait for the GPUVM flush to complete. There was some confusion as to how this mechanism was supposed to work. The operation is not atomic.

The power management code calls into the display code for certain things. If certain power management sysfs attributes are called before the driver has finished initializing all of the hardware we can run into problems with uninitialized modesetting state. Add a check to make sure modesetting init has completed to the bandwidth update callbacks to fix this.

This patch moves to radeon the initialization of compute vmid.

2014-08-05drm/radeon: Use pflip irqs for pageflip completion if possible. (v2)Mario Kleiner1-1/+2
Skip the "manual" pageflip completion checks via polling and guessing in the vblank handler radeon_crtc_handle_vblank() on asics which are known to reliably support hw pageflip completion irqs. Those pflip irqs are a more reliable and race-free method of handling pageflip completion detection, whereas the "classic" polling method has some small races in combination with dpm on, and with the reworked pageflip implementation since Linux 3.16. On old asics without pflip irqs, the classic method is used. On asics with known good pflip irqs, only pflip irqs are used by default, but a new module parameter "use_pflipirqs" allows to override this in case we encounter asics in the wild with unreliable or faulty pflip irqs. A module parameter of 0 allows to use the classic method only in such a case. A parameter of 1 allows to use both classic method and pflip irqs as additional band-aid to avoid some small races which could happen with the classic method alone. The setting 1 gives Linux 3.16 behaviour. Hw pflip irqs are available since R600. Tested on DCE-4, AMD Cedar - FirePro 2270. v2: agd5f: only enable pflip interrupts on DCE4+ as they are not reliable on older asics.

2014-07-15drm/radeon: Add radeon <--> amdkfd interfaceOded Gabbay1-0/+10
This patch adds the interface between the radeon driver and the amdkfd driver. The interface implementation is contained in radeon_kfd.c and radeon_kfd.h. The interface itself is represented by a pointer to struct kfd_dev. The pointer is located inside radeon_device structure. All the register accesses that amdkfd need are done using this interface. This allows us to avoid direct register accesses in amdkfd proper, while also avoiding locking between amdkfd and radeon. The single exception is the doorbells that are used in both of the drivers. However, because they are located in separate pci bar pages, the danger of sharing registers between the drivers is minimal. Having said that, we are planning to move the doorbells as well to radeon. v3: Add interface for sa manager init and fini. The init function will allocate a buffer on system memory and pin it to the GART address space via the radeon sa manager. All mappings of buffers to GART address space are done via the radeon sa manager. The interface of allocate memory will use the radeon sa manager to sub allocate from the single buffer that was allocated during the init function. Change lower_32/upper_32 calls to use linux macros Add documentation for the interface v4: Change ptr field type in kgd_mem from uint32_t* to void* to match to type that is returned by radeon_sa_bo_cpu_addr v5: Change format of mqd structure to work with latest KV firmware Add support for AQL queues creation to enable working with open-source HSA runtime.
