In a virtual environment, device drivers such as legacy IDE will waste quite a lot of time probing for their devices which will never appear. This helper function allows a paravirt implementation to lay claim to the whole iomem and ioport space, thereby disabling all device drivers trying to claim IO resources.

Hello! I'm getting this backtrace every time I boot: resource map sanity check conflict: 0xf0000000 0xf1ffffff 0xf1000000 0xf112bfff BOOTFB ------------[ cut here ]------------ WARNING: CPU: 6 PID: 1 at /home/proskin/src/linux/arch/x86/mm/ioremap.c:171 __ioremap_caller+0x372/0x380() Info: mapping multiple BARs.

Hello! I have spent some time on the issue. I'm not sure it's a nouveau bug. I have a fix that changes arch/x86/kernel/sysfb_simplefb.c only. GRUB actually uses graphic mode on my card. That mode is supported by simplefb. However, the resource conflict happens regardless of whether simplefb is enabled. It's sysfb_simplefb that causes it, a completely different driver. If GRUB

paravirt_disable_iospace() isn't used anywhere. Remove it.

IORESOURCE_MEM_DRIVER_MANAGED currently uses an unused PnP bit, which is always set to 0 by hardware. This is far from beautiful (and confusing), and the bit only applies to SYSRAM. So let's move it out of the bus-specific (PnP) defined bits. We'll add another SYSRAM specific bit soon. If we ever need more bits for other purposes, we can steal some from "desc", or

Hi folks, With this series, the bulk of the work of pvops64 is done. Here, I integrate most of the paravirt.c and paravirt.h files, making them applicable to both architectures. CONFIG_PARAVIRT is _not_ present yet. Basically, this code is missing page table integration (patches currently being worked on by Jeremy). Enjoy

Move header includes for the nopud / nopmd types to the location of the actual pte / pgd type definitions. This allows generic 4-level page type code to be written before the split 2/3 level page table headers are included.

Some paravirtualized devices that add memory via add_memory() and friends (esp. virtio-mem) don't want to create entries in /sys/firmware/memmap/ - primarily to hinder kexec from adding this memory to the boot memmap of the kexec kernel. In fact, such memory is never exposed via the firmware (e.g., e820), but only via the device, so exposing this memory via /sys/firmware/memmap/ is wrong:
