If a command is using a profiling buffer, make sure that the offset is within the bounds of the specified memory descriptor. Change-Id: Ic0dedbadc77e8eccd957136467bd0c56a1af2dab Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Deepak Kumar <dkumar@codeaurora.org>
To prepare to allow global buffers to allocate a semi-random GPU address move from a sequential allocator to a bitmap based one. Adapted to the SODP 4.9 kernel to use macros with `(mmu)` arguments: `GLOBAL_MAP_PAGES(mmu)` and `KGSL_IOMMU_GLOBAL_MEM_SIZE(mmu)` and `KGSL_IOMMU_GLOBAL_MEM_SIZE_NG >> PAGE_SHIFT` instead of `GLOBAL_MAP_PAGES` in `DECLARE_BITMAP` Change-Id: Ic0dedbadba36c4c7b7839528103997724eac7d6d Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Deepak Kumar <dkumar@codeaurora.org> Signed-off-by: ix5 <ix5@users.noreply.github.com>
Execute user profiling in an indirect buffer. This ensures that addresses and values specified directly from the user don't end up in the ringbuffer. FIXME: Felix: Left a comment in adreno_ringbuffer.c about dword length for legacy, needs to be adressed!

@ix5 [WIP] can be removed? Or still something open? |

@stefanhh0 I really wouldn't like to break other devices, but it seems this is ok to merge now. |
