alistair23 · airlied · commit 17fb465f1602 · 2019-02-28T14:05:33.000+10:00
When running RISC-V QEMU with the Bochs device attached via PCIe the probe of the Bochs device fails with: [drm:bochs_hw_init] *ERROR* ID mismatch This was introduced by this commit: 7780eb9 bochs: convert to drm_dev_register To fix the error we ensure that pci_enable_device() is called before bochs_load().
