...And I found the three lines in "dmesg" output: XENBUS: Device with no drvier: device/vbd/51713 XENBUS: Device with no driver: device/pci/0 XENBUS: Device with no driver: device/vif/0 After that, I tried to rebuild redhat4.5''s kernel, and set: CONFIG_PCI=y CONFIG_XEN_PCIDEV_FRONTEND=y in the config file "kernel-2.6.9-i686-xenU.config". But the new kernel make no difference in the above scenario. I found, in the file "kernel-2.6.9-i686-xenU.config" that "CONFIG_PCI is not set" appears twice, one of whi...

I do see some advantage in making Nouveau build with !CONFIG_PCI because it allows building the driver for an SoC without PCI. But I think always compiling whatever is available won't hurt. Nouveau itself is rather big (~1 MiB of text and ~120 KiB...

Hi all, this little series removes the last swiotlb API exposed to modules.

Some notebook systems provide the EDID for the internal panel via the _DDC method in ACPI, instead of or in addition to providing the EDID via DDC on LVDS/eDP. Add a DRM helper to search for an ACP _DDC method under the ACPI namespace for each VGA/3D controller, and return the first EDID successfully retrieved via _DDC. Update the i915, nouveau, and radeon DRM-KMS drivers to fall back to

...nced error reporting to work on 5.5. The info I need to start with is the following: 1) Is PCIe Advanced Error Reporting (including error injections) known to work in 5.5? 2) What configuration options do I need to select in order to enable it? I'm using the following configs: CONFIG_ACPI=y CONFIG_PCI=y CONFIG_PCI_DIRECT=y CONFIG_PCI_MMCONFIG=y CONFIG_PCIEPORTBUS=y CONFIG_PCIEAER=y CONFIG_PCIE_ECRC=y CONFIG_PCIE_AER_INJECT=y CONFIG_PCI_DOMAINS=y CONFIG_PCI_MSI=y I also have the kernel boot parameter aerdriver.forceload=y With this config, I see that the relevant devices appear to support Advan...
