The pdev field in struct drm_device points to a PCI device structure and goes back to UMS-only days when all DRM drivers were for PCI devices. Meanwhile we also support USB, SPI and platform devices. Each of those uses the generic device stored in struct drm_device.dev. To reduce duplication and remove the special case of PCI, this patchset converts all modesetting drivers from pdev to dev and makes pdev a field for legacy UMS drivers. For PCI devices, the pointer in struct drm_device.dev can be upcasted to struct pci_device; or tested for PCI with dev_is_pci(). In several places the code can use the dev field directly. After converting all drivers and the DRM core, the pdev fields becomes only relevant for legacy drivers. In a later patchset, we may want to convert these as well and remove pdev entirely.On the series, Reviewed-by: Jani Nikula <jani.nikula@xxxxxxxxx> How should we merge these?
Thanks for the quick reply.There is another pdev patch that I just sent out. [1] It has to go into the intel tree. After it landed, I want to get this patchset into drm-misc-next ASAP. Otherwise, drm-tip would stop building.
This should fix things in the correct order and finally remove pdev for current drivers.
