Subject: [PATCH v3 0/8] drivers/soc: Add Aspeed XDMA Engine Driver
Date: Wed, 29 May 2019 13:10:00 -0500 [thread overview]
Message-ID: <1559153408-31190-1-git-send-email-eajames@linux.ibm.com> (raw)
The XDMA engine embedded in the AST2500 SOC performs PCI DMA operations
between the SOC (acting as a BMC) and a host processor in a server.
This series adds a driver to control the XDMA engine in order to easily
perform DMA operations to and from the host processor.
Changes since v2:
- Switch to one pci device config sysfs file
- Add documentation for pci device config sysfs file
- Add module parameter for pci device config
- Switch to genalloc instead of custom allocator
- Fix alignment of user structure
- Cleaned up debugfs functions
I previously sent this series v1 to drivers/misc, but I'm now fairly certain
it belongs in drivers/soc, especially since the other Aspeed drivers have been
moved to soc.
Changes since v1:
- Correct the XDMA command pitch
- Don't use packed for the aspeed_xdma_op structure
- Correct the SCU PCI config change
