There is a Vivante GC1000 (v5037) in LS2K1000 and LS7A1000, this GPU is a
PCI device, and it has 2D and 3D cores in the same core. This series is
trying to add PCI device driver support to drm/etnaviv.

v6:
	* Fix build issue on system without CONFIG_PCI enabled
v7:
	* Add a separate patch for the platform driver rearrangement (Bjorn)
	* Switch to runtime check if the GPU is dma coherent or not (Lucas)
	* Add ETNAVIV_PARAM_GPU_COHERENT to allow userspace to query (Lucas)
	* Remove etnaviv_gpu.no_clk member (Lucas)
	* Various Typos and coding style fixed (Bjorn)
v8:
	* Fix typos and remove unnecessary header included (Bjorn).
	* Add a dedicated function to create the virtual master platform
	  device.
v9:
	* Use PCI_VDEVICE() macro (Bjorn)
	* Add trivial stubs for the PCI driver (Bjorn)
	* Remove a redundant dev_err() usage (Bjorn)
	* Clean up etnaviv_pdev_probe() with etnaviv_of_first_available_node()
v10:
	* Add one more cleanup patch
	* Resolve the conflict with a patch from Rob
	* Make the dummy PCI stub inlined
	* Print only if the platform is dma-coherrent

Rob Herring (1):
  drm/etnaviv: Replace of_platform.h with explicit includes

Sui Jingfeng (10):
  drm/etnaviv: Add a dedicated function to register an irq handler
  drm/etnaviv: Add a dedicated function to get various clocks

  drm/etnaviv: Add helpers for private data construction and destruction
  drm/etnaviv: Allow bypass component framework
  drm/etnaviv: Add driver support for the PCI devices
  drm/etnaviv: Add support for the dma coherent device

Is it possible to get the lspci output for the GPU? Something like
this: sudo lspci -vvv -s ...

Hi,

Below is the gpu info cat from the debugfs,

I guess this is also what you want ?
