* [PATCH] i386: Some additional chipset register values validation.Olivier Galibert2007-05-021-8/+17
| | | | | | | | | | | | | | | | | On i945, a mmconfig range hitting the f0000000-ffffffff zone conflicts with the APIC registers and others. Consider it invalid. On E7520, values 0000 and f000 for the window register are defined invalid in the documentation. I haven't seen a bios use these values, but who trusts biosen these days?

* [PATCH] mmconfig: Move e820 check into pci_mmcfg_reject_broken()OGAWA Hirofumi2007-02-131-20/+31
| | | | | | | This is just cleanup. It moves to e820 check into pci_mmcfg_reject_broken(). Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Signed-off-by: Andi Kleen <ak@suse.de>
* [PATCH] mmconfig: fix unreachable_devices()OGAWA Hirofumi2007-02-131-5/+7
| | | | | | | | Currently, unreachable_devices() compares value of mmconfig and value of conf1. But it doesn't check the device is reachable or not. Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Signed-off-by: Andi Kleen <ak@suse.de>

* [PATCH] mmconfig: Reject a broken MCFG tables on Asus etcOGAWA Hirofumi2007-02-131-1/+23
| | | | | | | | | | This rejects broken MCFG tables on Asus. When the table looks bogus just disable mmconfig Arjan and Andi suggested this. Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Signed-off-by: Andi Kleen <ak@suse.de>
* [PATCH] mmconfig: Reserve resources but only when we're sure about them.Olivier Galibert2007-02-131-0/+33
| | | | | | | | | | | Put back the resource reservation as per 4c6e052adfe285ede5884e4e8c4d33af33932c13 but use it *only* when the range(s) come from a chipset probe instead of the bios.

* [PATCH] mmconfig: Detect and support the E7520 and the 945G/GZ/P/PLOlivier Galibert2007-02-131-2/+119
| | | | | | | | | | | It seems that the only way to reliably support mmconfig in the presence of funky biosen is to detect the hostbridge and read where the window is mapped from its registers. Do that for the E7520 and the 945G/GZ/P/PL for a start.

* [PATCH] i386: Only call unreachable_devices() when type 1 is available.Olivier Galibert2007-02-131-1/+2
| | | | | | | | | | | unreachable_devices compares between the results of pci configuration accesses through type1 and mmconfig, so it should be called only if type1 actually works in the first place.

* [PATCH] mmconfig: Share parts of mmconfig code between i386 and x86-64Olivier Galibert2007-02-131-0/+86
i386 and x86-64 pci mmconfig code have a lot in common. So share what's shareable between the two. Signed-off-by: Olivier Galibert <galibert@pobox.com> Signed-off-by: Andi Kleen <ak@suse.de> Cc: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org>
