Subject: [PATCH] agpgart fixes (Intel chipsets)
Date: Mon, 26 Nov 2001 08:19:16 +0100 [thread overview]
Message-ID: <3C01ECF4.3000500@epfl.ch> (raw)
[-- Attachment #1: Type: text/plain, Size: 604 bytes --]
Hello
Here is a patch that fixes several issues in the agpgart driver :
- The 'cleanup' function for i820 chipsets was incorrectly set to the
generic function (that writes over 16 bits instead of 8)
- Fix incorrect PCI id for the i860 chipset
- Add support for the UP version of i820 chipset
- Config.in update
The patch is against 2.4.15
Best regards
