gpu: nvgpu: fix pbdma intr handling
To handle any of the pbdma interrupt, we currently write zero to pbdma_method0 and then clear the interrupt But this is insufficient since we cannot use same intr clear method for all the interrupts Hence, add intr specific routines to handle those interrupts NV_PPBDMA_INTR_0_PBENTRY: - fix the pb_header to have a null opcode - fix the pbdma_method to have a valid nop NV_PPBDMA_INTR_0_METHOD: - fix the pbdma_method to have a valid nop NV_PPBDMA_INTR_0_DEVICE: - fix the pb_header to have a null opcode - go through all pbdma_method0/1/2/3 -- if they contain host s/w methods, replace those methods with a valid NOP Bug 200134238 Change-Id: I10c284a6cdc1441f9d437cea65aae00d3c33a8c8 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/814561 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
