[Why] When we execute the first command for ASIC_INIT for command table offloading we can hit a timing scenario such that the interrupts for the inbox wptr haven't been enabled yet and the first command is ignored until the second command is sent. [How] This happens when either the SCRATCH0 is already the correct status code or autoload check is unsupported. Clear SCRATCH0 during reset. Also ensure that we don't accidentally reset the ASIC again in case of a hang by clearing GPINT while we're at it. Signed-off-by:

Currently there is a minor error in scaling filter coefficients caused by truncation to fit the HW registers.This error accummulates with increased taps, but has gone unnoticed due to vast majority of scaling being done with only 4 taps.

[Why] core_link_read_dpcd() will invoke dm_helpers_dp_read_dpcd(), which needs to read dpcd info with the help of aconnector. If aconnector (dc->links[i]->prev) is NULL, then dpcd status cannot be read. As a result, dpcd read fails and a line of error will be printed out in dmesg.log as: "*ERROR* Failed to found connector for link!" [How] Make sure that aconnector (dc->links[i]->prev) is not NULL, then read dpcd status. Signed-off-by:

Using a heavy-weight TLB flush once is not sufficient. Concurrent memory accesses in the same TLB cache line can re-populate TLB entries from stale texture cache (TC) entries while the heavy-weight TLB flush is in progress. To fix this race condition, perform another TLB flush after the heavy-weight one, when TC is known to be clean. Move the workaround into the low-level TLB flushing functions. This way they apply to amdgpu as well, and KIQ-based TLB flush only needs to synchronize once. Signed-off-by:
