This version\ncontains the few changes I mentioned in the review of v2. Would you be\nable to give it a last round of review ?\n\nFeel free to push the kernel changes whenever is convenient, and notify\nme when it will be done. I'll push this series right after.\n\nNaushir Patuck (2):\n include: linux: Add dma-buf.h and dma-heap.h UAPI headers\n libcamera: pipeline: ipa: raspberrypi: Use dma heap allocs for LS\n tables\n\n include/linux/bcm2835-isp.h | 4 +-\n include/linux/dma-buf.h | 50 ++++++\n include/linux/dma-heap.h | 53 +++++++\n include/linux/vc_sm_cma_ioctl.h | 135 ----------------\n src/ipa/raspberrypi/raspberrypi.cpp | 28 +++-\n .../pipeline/raspberrypi/dma_heaps.cpp | 84 ++++++++++\n .../pipeline/raspberrypi/dma_heaps.h | 31 ++++\n .../pipeline/raspberrypi/meson.build | 1 +\n .../pipeline/raspberrypi/raspberrypi.cpp | 49 ++----\n src/libcamera/pipeline/raspberrypi/vcsm.h | 149 ------------------\n 10 files changed, 257 insertions(+), 327 deletions(-)\n create mode 100644 include/linux/dma-buf.h\n create mode 100644 include/linux/dma-heap.h\n delete mode 100644 include/linux/vc_sm_cma_ioctl.h\n create mode 100644 src/libcamera/pipeline/raspberrypi/dma_heaps.cpp\n create mode 100644 src/libcamera/pipeline/raspberrypi/dma_heaps.h\n delete mode 100644 src/libcamera/pipeline/raspberrypi/vcsm.h"}
