From: Stephan Schreiber <[email protected]>
I noticed that the build-in int10 driver always reports
"Unable to retrieve all of segment 0x0C0000."
even though the entire BIOS data is retrieved with success.
The associated code is in hw/xfree86/int10/generic.c, in the function
xf86ExtendedInitInt10():
if (pci_device_read_rom(pInt->dev, vbiosMem) < V_BIOS_SIZE) {
xf86DrvMsg(screen, X_WARNING,
"Unable to retrieve all of segment 0x0C0000.\n");
}
The function pci_device_read_rom() is from libpciaccess; its return
value is not a size but an error status code: 0 means success.
If pci_device_read_rom() returns 0 for success, the warning is generated.
The proposed patch corrects the evaluation of the return value of
pci_device_read_rom() and of the supplied BIOS size.
