pcie display doesn't work for pioneer pcb 1.1 #113

Closed unicornx closed 4 months ago

unicornx commented 4 months ago

I found on sg2042-dev branch, with commit: "e7d0ed665196 drivers: pci: support msix in PCIe rc0 for milkv mainboard" in, my pioneer pcb 1.1 does't work when connecting display with the pcie port. But when I rollback to "4973498c7073 drm/amd/display: Support DRM_AMD_DC_FP on RISC-V", it does work.

if you have pionner pcb 1.1 or pcb 1.2，please revert "e7d0ed665196 drivers: pci: support msix in PCIe rc0 for milkv mainboard"

ok, thanks.

Though I am very hoping you can support old pcb board on sg2042-dev.

Close this issue anyway.

Originally the pcie card is in the socket near the DDR sockets. In latest design, only one of them can work.

Move the pcie card to another socket near the bottom of the box and this issue is resolved.
