| * | PCI: Use dev_info() rather than dev_err() for ROM validationAlex Deucher2017-12-181-2/+2
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | On AMD GPUs, we use several mechanisms to fetch the VBIOS ROM depending on the platform. We try to read the ROM via the ROM BAR and fall back to other methods in some cases. This leads to spurious error messages from the PCI ROM code which are harmless in our case. This leads to bugs being filed, etc. Change these to dev_info() rather than dev_err() to avoid that.

| | | | | | | | | | | | If we detect a invalid PCI option ROM (e.g., invalid ROM header signature), we should unmap it immediately and fail. It doesn't make any sense to return a mapped area with size of 0. I have seen this case on Intel GVTg vGPU, which has no VBIOS. It will not cause a real problem, but we should skip it as early as possible.

* PCI: Add comments about ROM BAR updatingBjorn Helgaas2016-11-291-0/+5
| | | | | | | | | | | | | | | | | | | | | pci_update_resource() updates a hardware BAR so its address matches the kernel's struct resource UNLESS it's a disabled ROM BAR. We only update those when we enable the ROM. It's not obvious from the code why ROM BARs should be handled specially. Apparently there are Matrox devices with defective ROM BARs that read as zero when disabled. That means that if pci_enable_rom() reads the disabled BAR, sets PCI_ROM_ADDRESS_ENABLE (without re-inserting the address), and writes it back, it would enable the ROM at address zero. Add comments and references to explain why we can't make the code look more rational. The code changes are from 755528c860b0 ("Ignore disabled ROM resources at setup") and 8085ce084c0f ("[PATCH] Fix PCI ROM mapping").

* PCI: Set ROM shadow location in arch code, not in PCI coreBjorn Helgaas2016-03-081-11/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | IORESOURCE_ROM_SHADOW means there is a copy of a device's option ROM in RAM. The existence of such a copy and its location are arch-specific. Previously the IORESOURCE_ROM_SHADOW flag was set in arch code, but the 0xC0000-0xDFFFF location was hard-coded into the PCI core. If we're using a shadow copy in RAM, disable the ROM BAR and release the address space it was consuming. Move the location information from the PCI core to the arch code that sets IORESOURCE_ROM_SHADOW. Save the location of the RAM copy in the struct resource for PCI_ROM_RESOURCE. After this change, pci_map_rom() will call pci_assign_resource() and pci_enable_rom() for these IORESOURCE_ROM_SHADOW resources, which we did not do before. This is safe because: - pci_assign_resource() will do nothing because the resource is marked IORESOURCE_PCI_FIXED, which means we can't move it, and - pci_enable_rom() will not turn on the ROM BAR's enable bit because the resource is marked IORESOURCE_ROM_SHADOW, which means it is in RAM rather than in PCI memory space. Storing the location in the struct resource means "lspci" will show the shadow location, not the value from the ROM BAR. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

* PCI: Convert pcibios_resource_to_bus() to take a pci_bus, not a pci_devYinghai Lu2013-12-211-1/+1

And we want to use them in resource allocation paths where we have the bus but not a device, so this patch converts them to take the pci_bus instead of the pci_dev: pcibios_resource_to_bus(struct pci_bus *bus, *bus_region, *resource) pcibios_bus_to_resource(struct pci_bus *bus, *resource, *bus_region) In fact, with standard PCI-PCI bridges, they only depend on the host bridge, because that's the only place address translation occurs, but we aren't going that far yet.

* PCI: Add PCI ROM helper for platform-provided ROM imagesMatthew Garrett2013-03-261-36/+31
| | | | | | | | | | | | | | | | | | It turns out that some UEFI systems provide apparently an apparently valid PCI ROM BAR that turns out to contain garbage, so the attempt in 547b52463 to prefer the ROM from the BAR actually breaks a different set of machines. As Linus pointed out, the graphics drivers are probably in the best position to make this judgement, so this basically reverts 547b52463 and f9a37be0f and adds a new helper function. Followup patches will add support to nouveau and radeon for probing this ROM source if they can't find a ROM from some other source.

| | | | | | | | | | | | | | | | Mantas Mikulėnas reported that his graphics hardware failed to initialise after commit f9a37be0f02a ("x86: Use PCI setup data"). The aim of this commit was to ensure that ROM images were available on some Apple systems that don't expose the GPU ROM via any other source. In this case, UEFI appears to have provided a broken ROM image that we were using even though there was a perfectly valid ROM available via other sources. The simplest way to handle this seems to be to just re-order pci_map_rom() and leave any firmare-supplied ROM to last.

As a result, embedded VGA need the way that the sysfs rom points to the Video BIOS of System RAM (0xC0000). PCI-to-PCI Bridge Architecture specification describes the condition whether or not PCI ROM forwards VGA compatible memory address. fixup_video suits this specification. Although the Video ROM generally implements in x86 code regardless of platform, some application such as X Window System can run this code by dosemu86.
