PCI: Fix infinite loop with ROM image of size 0

2015-05-09T22:16:13Z

commit 16b036af31e1456cb69243a5a0c9ef801ecd1f17 upstream. If the image size would ever read as 0, pci_get_rom_size() could keep processing the same image over and over again. Exit the loop if we ever read a length of zero. This fixes a soft lockup on boot when the radeon driver calls pci_get_rom_size() on an AMD Radeon R7 250X PCIe discrete graphics card.

pci: Fix files needing export.h for EXPORT_SYMBOL/THIS_MODULE

2011-10-31T23:31:22Z

They were implicitly getting it from device.h --> module.h but we want to clean that up. So add the minimal header for these macros. Signed-off-by: Paul Gortmaker

PCI: return error on failure to read PCI ROMs

2009-02-05T00:58:41Z

This patch makes the ROM reading code return an error to user space if the size of the ROM read is equal to 0. The patch also emits a warnings if the contents of the ROM are invalid, and documents the effects of the "enable" file on ROM reading. Signed-off-by: Timothy S.

[IA64] SN: Correct ROM resource length for BIOS copy

2007-07-09T20:37:18Z

On SN systems, when setting the IORESOURCE_ROM_BIOS_COPY resource flag, the resource length should be set to the actual size of the ROM image so that a call to pci_map_rom() returns the correct size. Signed-off-by: John Keller Signed-off-by: Andrew Morton Signed-off-by: Tony Luck

Altix: Initial ACPI support - ROM shadowing.

2006-12-01T22:36:58Z

Support a shadowed ROM when running with an ACPI capable PROM. Define a new dev.resource flag IORESOURCE_ROM_BIOS_COPY to describe the case of a BIOS shadowed ROM, which can then be used to avoid pci_map_rom() making an unneeded call to pci_enable_rom().
