dmaengine: dw-axi-dmac: Drop obsolete dependency on COMPILE_TEST

2022-09-05T06:31:55Z

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues.

dmaengine: sun6i: Add support for the D1 variant

2022-05-19T18:13:41Z

So far it appears to match the configuration of the A100 variant. Since D1 is a RISC-V chip, it does not meet any of the existing dependencies for this driver, so relax the dependency somewhat.

Add support for AMD PTDMA controller. It performs high-bandwidth memory to memory and IO copy operation. Device commands are managed via a circular queue of 'descriptors', each of which specifies source and destination addresses for copying a single buffer of data.

dmaengine: idxd: fix setting up priv mode for dwq

2021-08-29T13:44:20Z

DSA spec says WQ priv bit is 0 if the Privileged Mode Enable field of the PCI Express PASID capability is 0 and pasid is enabled. Make sure that the WQCFG priv field is set correctly according to usage type. Reject config if setting up kernel WQ type and no support. Also add the correct priv setup for a descriptor.
