Re: [Xen-devel] VGA Passthrough on Xen 4.1: succees (IGD) and failure (ATI) report

[Gennady Marchenko <gennady.marchenko@xxxxxxxxx>]

This patch doesnt work for me cause patched current sources can't be compiled with following error :((( :

            TARGET_CFLAGS="-mno-red-zone -O1 -fno-omit-frame-pointer  -m64 -mno-red-zone -fno-reorder-blocks -fno-asynchronous-unwind-tables -m64 -g -fno-strict-aliasing -std=gnu99 -Wall -Wstrict-prototypes -Wno-unused-value -Wdeclaration-after-statement -Wno-unused-but-set-variable  -fno-stack-protector -fno-exceptions" \

            TARGET_LDFLAGS="-nostdlib -L/usr/src/xen-unstable.hg/stubdom/cross-root-x86_64/x86_64-xen-elf/lib" \

            ./xen-setup-stubdom )

And I can't fix it.

How does this patch work for you? You also need to install latest ATI driver
in guest.
