A second-level user mode trap handler can be installed. The CWSR trap handler jumps to the secondary trap handler conditionally for any conditions not handled by it. This can be used e.g. for debugging or catching math exceptions. When CWSR is disabled, the user mode trap handler is installed as first level trap handler. Signed-off-by:

This hardware feature allows the GPU to preempt shader execution in the middle of a compute wave, save the state and restore it later to resume execution. Memory for saving the state is allocated per queue in user mode and the address and size passed to the create_queue ioctl. The size depends on the number of waves that can be in flight simultaneously on a given ASIC. Signed-off-by:

The trap handler is like an interrupt handler running on the GPU compute unit. It is needed for supporting CWSR (compute wave save/restore). This file defines an array with the pre-compiled GFXv8 shader ISA. The assembly code is included for reference in #if 0 ... #endif. Signed-off-by:

Save wptr in hqd_sdma_destroy, restore it in hqd_sdma_load. Also read updated wptr from user mode when resuming an SDMA queue. Signed-off-by:

Felix Kuehling authored
Add wptr and mm parameters to hqd_sdma_load and pass these parameters from device_queue_manager through the mqd_manager. SDMA doesn't support polling while the engine believes it's idle. The driver must update the wptr. The new parameters will be used for looking up the updated value from the specified mm when SDMA queues are resumed after being disabled. Signed-off-by:

validate_fbc never fails a modeset. It's simply used to decide whether to use FBC or not. Calling it validate_fbc might be confusing to some so rename it to should_enable_fbc. With that let's also remove the DC_STATUS return code and return bool and make enable_fbc a void function since we never check it's return value and probably never want to anyways. Signed-off-by:

Original applied dm_restore_drm_connector_state() has got removed. Set link status to BAD before hotplug() event could trigger another modeset from userspace. The fix "Fix MST daisy chain SST not light up" commit makes so it is trying to create a stream prior to dc_sink. That makes dc_sink is not present in create_stream_for_sink(). Signed-off-by:
