Hi Mao, I have installed a version of the kernel which ignores the capabilities of the PCI bridge when determining whether a device can be the boot device. With this patched kernel, X starts without needing a config file. This confirms: - that the vga card is not marked as boot device because

Hi Mao, I have looked at the PCI setup a bit more closely: the VGA card is behind a PCI bridge which does not advertise the PCI_BRIDGE_CTL_VGA capability, so it is not being picked up by the kernel as the default/boot card. Is there anything special about the bridge or the hardware in this

Hi, I can get xorg working if I do these 2 things: 1) Edit memory with gdb to add "pci:" to bus id. This is what the kernel patch should do. I will test the patch soon, I am just waiting for the kernel to build. 2) Install this /etc/X11/xorg.conf: Section "ServerFlags" Option

Hi, On further investigation it turns out that one large difference between my x86 system and the arm64 system is they way the vga arbiter is operating in the kernel. This means that the vga card isn't labelled as the "boot vga" card, which affects how it's picked up by X. On the HiSilicon

[Bug 1691991] Re: Xorg Segmentation fault on Hisilicon D05 board (arm64)

Ok, so I think part of the problem is that the kernel hibmc driver needs to use a set_busid function from the drm core. I've simulated this change in the debugger, and it seems to at least prevent the crash. (It doesn't seem to be enough for the server to work, still working on that.) Here's a

OK, I have made some progress on this: The busid reported by libdrm on the arm64 system is "0007:a1:00.0" The busid reported by libdrm on a amd64 system is "pci::00:02.0" The "pci:" prefix is missing on arm64. I think this leads to the segfault on arm64 as X tests for the prefix. This
