The wave's number per simd in aldebaran is changed to 8, so it is impossible to use old algorithm to initiate all sgprs with one threadgroup. The new algorithm firstly use three threadgroups to initiate most sgprs simultaneously and then use another threadgroup with 4 waves to cover other uninitiated sgprs. v2: Add more description about the new algorithm to clear sgprs and add some comment for shader binaries Signed-off-by:

After draining the stale retry fault, or failed to validate the range to recover, have to remove the fault address from fault filter ring, to be able to handle subsequent retry interrupt on same address. Otherwise the retry fault will not be processed to recover until timeout passed. Signed-off-by:

Add interface to remove address from fault filter ring by resetting fault ring entry key, then future vm fault on the address will be processed to recover. Define fault key as atomic64_t type to use atomic read/set/cmpxchg key to protect fault ring access by interrupt handler and interrupt deferred work for vg20. Change fault->timestamp to 48-bit to share same uint64_t with 8-bit fault->next, it is enough for 48bit IH timestamp. Signed-off-by:

Retry fault interrupt maybe pending in IH ring after GPU page table is updated to recover the vm fault, because each page of the range generate retry fault interrupt. There is race if application unmap range to remove and free the range first and then retry fault work restore_pages handle the retry fault interrupt, because range can not be found, this vm fault can not be recovered and report incorrect GPU vm fault to application. Before unmap to remove and free range, drain retry fault interrupt from IH ring1 to ensure no retry fault comes after the range is removed. Drain retry fault interrupt skip the range which is on deferred list to remove, or the range is child range, which is split by unmap, does not add to svms and have interval notifier. Signed-off-by:

Sometimes IH do not setup ring wptr overflow flag after wptr exceed rptr. As a workaround, if IH rptr equals to wptr, ring is empty, return true to indicate IH ring checkpoint is processed, IH ring drain is finished. Signed-off-by:

[why] As hardware team suggested that we need to add a max dsc bw overhead into existing stream bandwidth when DSC is used. The formula as below: max_dsc_bw_overhead = v_addressable * slice_count * 256 bit * pixel clock / v_total / h_total effective stream bandwidth = pixel clock * bpp stream bandwidth = effective stream bandwidth + dsc stream overhead Signed-off-by:
