2018-05-01drm/amdkfd: Add sanity checks in IRQ handlersFelix Kuehling2-21/+39
Only accept interrupts from KFD VMIDs. Just checking for a PASID may not be enough because amdgpu started using PASIDs to map VM faults to processes.

It turns out that idr_for_each_entry is really slow compared to just iterating over the slots. Based on measurements the difference is estimated to be about a factor 64.

2018-05-01drm/amdkfd: Separate trap handler assembly code and its hex valuesYong Zhao4-555/+575
Since the assembly code is inside "#if 0", it is ineffective. Despite that, during debugging, we need to change the assembly code, extract it into a separate file and compile the new file into hex values using sp3. That process also requires us to remove "#if 0" and modify lines starting with "#", so that sp3 can successfully compile the new file. With this change, all the above chore is no longer needed, and cwsr_trap_handler_gfx*.asm can be directly used by sp3 to generate its hex values.

2018-05-01drm/amdkfd: Use volatile MTYPE in default/alternate aperturesJay Cornwall1-1/+2
MTYPE_NC_NV (0) marks scalar/vector L1 cache lines as non-volatile. Cache lines loaded through these apertures are intended to be invalidated before (and sometimes during) a dispatch. The non-volatile qualifier prevents these cache lines from being distinguished from those loaded through the private aperture. Use MTYPE_NC (1) instead on both Gfx7 and Gfx8. This allows the compiler to use the BUFFER_WBINVL1_VOL instruction and is a precursor to automatic per-dispatch scalar/vector L1 volatile invalidation.

2018-05-01drm/amdkfd: Reduce priority of context-saving waves before spin-waitJay Cornwall2-3/+15
Synchronization between context-saving wavefronts is achieved by sending a SAVEWAVE message to the SPI and then spin-waiting for a response. These spin-waiting wavefronts may inhibit the progress of other wavefronts in the context save handler, leading to the synchronization condition never being achieved. Before spin-waiting reduce the priority of each wavefront to guarantee foward progress in the others.

2018-04-10drm/amdkfd: Try to enable atomics for all GPUswelu1-14/+13
Report failure to enable atomics only on GPUs that require them. This allows GPUs that don't require atomics to function, but can benefit if they are available. This is the case for Vega10, which doesn't use atomics for basic functioning of the MEC, AQL and HWS microcode. So it can work without atomics. But shader programs can still use atomic instructions on systems that support PCIe atomics.

2018-03-15drm/amdkfd: Remove limit on number of GPUsFelix Kuehling2-12/+104
Currently the number of GPUs is limited by aperture placement options available on GFX7 and GFX8 hardware. This limitation is not necessary. Scratch and LDS represent per-work-item and per-work-group storage respectively. Different work-items and work-groups use the same virtual address to access their own data. Work running on different GPUs is by definition in different work-groups (different dispatches, in fact). That means the same virtual addresses can be used for these apertures on different GPUs. Add a new AMDKFD_IOC_GET_PROCESS_APERTURES_NEW ioctl that removes the artificial limitation on the number of GPUs that can be supported. The new ioctl allows user mode to query the number of GPUs to allocate enough memory for all GPUs to be reported. This deprecates AMDKFD_IOC_GET_PROCESS_APERTURES.
