This topic has already been concerned on v1 (in another context though): https://lore.kernel.org/dmaengine/20230621151948.36125997@kmaincent-XPS-13-7390/ Here is the repo with the out-of-tree driver Kory said he was using together with the kernel's version of the DW eDMA/hDMA driver: https://github.com/Brainchip-Inc/akida_dw_edma -Serge(y) > > - Mani > > > Changes in v2: > > - Update comments and fix typos. > > - Removed patches that tackle hypothetical bug and then were not pertinent. > > - Add the similar HDMA race condition in remote setup fix to eDMA IP driver. > > > > Changes in v3: > > - Fix comment style. > > - Split a patch in two to differ bug fix and simple harmless typo. > > > > Changes in v4: > > - Update patch git commit message. > > - Link to v3: https://lore.kernel.org/r/20231011-b4-feature_hdma_mainline-v3-0-24ee0c979c6f@xxxxxxxxxxx > > > > Changes in v5: > > - No change > > - Rebase to mainline 6.7-rc1 > > - Link to v4: https://lore.kernel.org/r/20231011-b4-feature_hdma_mainline-v4-0-43d417b93138@xxxxxxxxxxx > > > > Changes in v6: > > - Fix several commit messages and comments. > > - Link to v5: https://lore.kernel.org/r/20231114-b4-feature_hdma_mainline-v5-0-7bc86d83c6f7@xxxxxxxxxxx > > > > Signed-off-by: Kory Maincent <kory.maincent@xxxxxxxxxxx> > > --- > > Kory Maincent (6): > > dmaengine: dw-edma: Fix the ch_count hdma callback > > dmaengine: dw-edma: Fix wrong interrupt bit set for HDMA > > dmaengine: dw-edma: HDMA_V0_REMOTEL_STOP_INT_EN typo fix > > dmaengine: dw-edma: Add HDMA remote interrupt configuration > > dmaengine: dw-edma: HDMA: Add sync read before starting the DMA transfer in remote setup > > dmaengine: dw-edma: eDMA: Add sync read before starting the DMA transfer in remote setup > > > > drivers/dma/dw-edma/dw-edma-v0-core.c | 17 +++++++++++++++ > > drivers/dma/dw-edma/dw-hdma-v0-core.c | 39 +++++++++++++++++++++++------------ > > drivers/dma/dw-edma/dw-hdma-v0-regs.h | 2 +- > > 3 files changed, 44 insertions(+), 14 deletions(-) > > --- > > base-commit: b85ea95d086471afb4ad062012a4d73cd328fa86 > > change-id: 20231011-b4-feature_hdma_mainline-b6c57f8e3b5d > > > > Best regards, > > -- > > Köry Maincent, Bootlin > > Embedded Linux and kernel engineering > > https://bootlin.com > > > > -- > மணிவண்ணன் சதாசிவம்
