Author: uwe Date: 2007-10-14 02:29:25 +0200 (Sun, 14 Oct 2007) New Revision: 2853
Modified: trunk/LinuxBIOSv2/src/northbridge/amd/amdk8/northbridge.c Log: Fix the resource end in amdk8/northbridge.c. Without this bugfix, the resource for the PCI/ISA video memory at 0xa0000 - 0xbffff is too big, i.e. it goes up to 0xcffff instead of just 0xbffff as it should. Here's the diff from two runs of the tool from http://www.linuxbios.org/pipermail/linuxbios/2007-June/022449.html on the MSI MS-7260 (K9N Neo), with and without the bugfix. After applying, the resource size is correct again. --- dumpres_lb_pci_vgacard_without_resfix.txt +++ dumpres_lb_pci_vgacard_with_resfix.txt @@ -11,7 +11,7 @@ MMIO map: #2 0x0000000000 - 0x000000ffff Access: / Dstnode:0 DstLink 0 MMIO map: #3 0x0000000000 - 0x000000ffff Access: / Dstnode:0 DstLink 0 MMIO map: #4 0x0000000000 - 0x000000ffff Access: / Dstnode:0 DstLink 0 -MMIO map: #5 0x00000a0000 - 0x00000cffff Access: R/W Dstnode:0 DstLink 0 +MMIO map: #5 0x00000a0000 - 0x00000bffff Access: R/W Dstnode:0 DstLink 0 MMIO map: #6 0x00fc000000 - 0x00fd1fffff Access: R/W Dstnode:0 DstLink 0 MMIO map: #7 0x00fd200000 - 0x00fd1fffff Access: R/W Dstnode:0 DstLink 0 MMIO map: #0 0x000000 - 0x003fff Access: R/W ISA VGA Dstnode:0 DstLink 0 Signed-off-by: Rudolf Marek <[EMAIL PROTECTED]> Acked-by: Carl-Daniel Hailfinger <[EMAIL PROTECTED]> Acked-by: Uwe Hermann <[EMAIL PROTECTED]> Modified: trunk/LinuxBIOSv2/src/northbridge/amd/amdk8/northbridge.c =================================================================== --- trunk/LinuxBIOSv2/src/northbridge/amd/amdk8/northbridge.c 2007-10-13 18:06:12 UTC (rev 2852) +++ trunk/LinuxBIOSv2/src/northbridge/amd/amdk8/northbridge.c 2007-10-14 00:29:25 UTC (rev 2853) @@ -562,7 +562,7 @@ base |= (resource->base >> 8) & 0xffffff00; base |= 3; limit &= 0x00000048; - limit |= ((resource->base + resource->size) >> 8) & 0xffffff00; + limit |= (resource_end(resource) >> 8) & 0xffffff00; limit |= (resource->index & 3) << 4; limit |= (nodeid & 7); f1_write_config32(reg + 0x4, limit); -- linuxbios mailing list [email protected] http://www.linuxbios.org/mailman/listinfo/linuxbios
