| * | | | | | msm: kgsl: Add MEMDESC_MAPPED back to for legacy mappingsCarter Cooper2016-10-13
| | |_|/ / / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We still need to keep this internal flag for non-sparse mappings. Add back so we don't map multiple times if the range is already mapped. Change-Id: Ifcf6073b5b778bcb535d26bc33990254ff48c406 Signed-off-by: Carter Cooper <ccooper@codeaurora.org>

| * | | msm: kgsl: Clear the interrupt immediatelyHarshdeep Dhatt2016-10-14
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes an interrupt from GPU is ignored while we are still executing the previous interrupt. In order to service any interrupt that was fired while executing the interrupt handler, clear the interrupt register immediately. Also, clear the ADRENO_INT_RBBM_AHB_ERROR bit not before but after it's serviced in its respective handler. This will avoid firing the main interrupt handler a second time.

| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we free up the gpuaddr range whether unmap succeeds or fails. If it fails and we free up the gpuaddr range, there is a possibility that a later allocation will overlap with this range. Mapping this new range leads to a BUG_ON() in the iommu driver which thinks that we are overwriting an existing mapping. To avoid this, we never free the failing gpuaddr range, effectively removing it from being re-used for any future mappings.
