| |
Hi,
I have two patches that address a couple of issues I've run into with the PCIe DWC host driver: (1) the host driver fails to probe when ZONE_DMA32 is disabled. (2) the host driver will fail to probe if a 32-bit address is not available even on devices that support 64-bit target addresses.
I have addressed both of these issues with the two patches (details can found in each of the patch commit messages). Please take a look and let me know your thoughts.
With regards to testing, I have verified them on Android with a Pixel 6 device on the 5.19 + pci-v5.20-changes kernel. My testing included running with both ZONE_DMA32 and swiotlb disabled.
Thanks, Will
