KG http://www.secnetix.de/bsd >Environment: The patch applies and works on 8.1, 8-stable and HEAD. The patch applies cleanly on 7-stable, too, but I haven't tested whether it actually works. >Description: I've recently bought a new mainboard "M4A88TD-V EVO/USB3" from ASUS. This mainboard is gaining high popularity because it features USB 3.0, SATA-3 and other things, while still providing legacy stuff (serial RS232, PS/2 connector for mouse/keyboard) and being rather inexpensive. This board has a newer version of the RS880 chip; the graphics is identified as "Radeon HD 4250". The one-line patch below makes it work. By the way, I noticed that Linux 2.6.33 has the same patch. With that patch, DRM attaches and Xv acceleration works, so I can watch video fullscreen at nearly 0% CPU load. vgapci0: <VGA-compatible display> port 0xb000-0xb0ff mem 0xd0000000-0xdfffffff,0xfe8f0000-0xfe8fffff,0xfe700000-0xfe7fffff irq 18 at device 5.0 on pci1 drm0: <ATI Radeon HD 4250> on vgapci0 info: [drm] MSI enabled 1 message(s) vgapci0: child drm0 requested pci_enable_busmaster info: [drm] Initialized radeon 1.31.0 20080613 $ xvinfo X-Video Extension version 2.2 screen #0 Adaptor #0: "Radeon Textured Video" ... While Xv works now, 3D acceleration does not, unfortunately. But I think this is a different issue; I guess the chip is not yet supported by the GL code (but I'm not an expert in this area). >How-To-Repeat: >Fix: --- sys/dev/drm/drm_pciids.h.orig 2010-04-04 17:46:46.000000000 +0200 +++ sys/dev/drm/drm_pciids.h 2010-07-21 22:53:45.000000000 +0200 @@ -335,6 +335,7 @@ {0x1002, 0x9712, CHIP_RS880|RADEON_IS_MOBILITY|RADEON_NEW_MEMMAP|RADEON_IS_IGP, "ATI Mobility Radeon HD 4200"}, \ {0x1002, 0x9713, CHIP_RS880|RADEON_IS_MOBILITY|RADEON_NEW_MEMMAP|RADEON_IS_IGP, "ATI Mobility Radeon 4100"}, \ {0x1002, 0x9714, CHIP_RS880|RADEON_NEW_MEMMAP|RADEON_IS_IGP, "ATI RS880"}, \ + {0x1002, 0x9715, CHIP_RS880|RADEON_NEW_MEMMAP|RADEON_IS_IGP, "ATI Radeon HD 4250"}, \ {0x1002, 0x9440, CHIP_RV770|RADEON_NEW_MEMMAP, "ATI Radeon 4800 Series"}, \ {0x1002, 0x9441, CHIP_RV770|RADEON_NEW_MEMMAP, "ATI Radeon 4870 X2"}, \ {0x1002, 0x9442, CHIP_RV770|RADEON_NEW_MEMMAP, "ATI Radeon 4800 Series"}, \ >Release-Note: >Audit-Trail: >Unformatted:
