VIA KN133 and PN133 fails to auto-detect, missing driver name in hwdata

From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.1a+) Gecko/20020623 Description of problem: In testing Red Hat Linux 7.3 on the Compaq Presario 700 series laptop, the video chipset failed to be auto-detected by both the installer and Xconfigurator. This laptop series has either Athlon Palomino or Duron Morgan CPU's with the VIA KN133 chipset. The KN133 chipset is basically the KT133A chipset with integrated video identified as "S3 Graphics Twister K Compaq" in Windows. After digging through some VIA specs and other reports on linux-laptop.net, it seems that the "S3 Savage4 Pro+" driver set to 16MB RAM works flawlessly in 2D (DRI 3D is not available with this chipset.) Do you need any more information to make auto-detect for this chipset to work? Perhaps also add to the PCI database? Possible to auto-detect the monitor (generic 1024x768 laptop display) too? Please let me know if you need any more information. Attached are the full lspci -vv and dmesg outputs. lspci -vv for this device ------------------------- 01:00.0 VGA compatible controller: S3 Inc.: Unknown device 8d02 (rev 01) (prog-if 00 [VGA]) Subsystem: Compaq Computer Corporation: Unknown device 0086 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66Mhz+ UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <P ERR- Latency: 64 (1000ns min, 63750ns max), cache line size 08 Interrupt: pin A routed to IRQ 5 Region 0: Memory at e8100000 (32-bit, non-prefetchable) [size=512K] Region 1: Memory at f0000000 (32-bit, prefetchable) [size=128M] Expansion ROM at <unassigned> [disabled] [size=64K] Capabilities: [dc] Power Management version 2 Flags: PMEClk- DSI+ D1+ D2+ AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 PME-Enable- DSel=0 DScale=0 PME- Capabilities: [80] AGP version 2.0 Status: RQ=31 SBA- 64bit- FW- Rate=<none> Command: RQ=0 SBA- AGP- 64bit- FW- Rate=<none> Version-Release number of selected component (if applicable): Red Hat Linux 7.3 How reproducible: Always Steps to Reproduce: 1.

Also what can I do to probe the hardware in order to submit laptop monitor autodetection info?

Your chip is not listed. Hopefully a future XFree86 release will support this chip. In the mean time, I'll default this chip to the 'vesa' driver. Sorry I can't do anything else for this. ;o/
Please, I think you misunderstood this report. It only fails to auto-detect the video chipset because it is not in the PCI ids, but if I manually select the S3 Savage4 Pro+ and 16MB VRAM it works flawlessly.
http://www.via.com.tw/en/ProSavage%20Chipsets/prosav_index.jsp The VIA KN133 in this Compaq notebook has the same integrated graphics controller as the KM133.
Within XFree86-4.2.0-55 and hwdata-0.33-1 are the following: line 125 of savage_driver.c: { PCI_CHIP_S3TWISTER_K, "ProSavage KN133" } line 5750 of pci.ids: 8d02 VT8636A [ProSavage KN133] AGP4X VGA Controller (TwisterK) Thus it appears to be only missing this #define statement? #define PCI_CHIP_PROSAVAGE_KN 0x8d02
Oops, I guess that would this instead #define PCI_CHIP_S3TWISTER_K 0x8d02 If I am completely wrong on this one, please let me know. I am trying my best to learn and help out.
ops, I just found the following in savage_regs.h: /* These are here until xf86PciInfo.h is updated. */ #ifndef PCI_CHIP_S3TWISTER_P #define PCI_CHIP_S3TWISTER_P 0x8d01 #endif #ifndef PCI_CHIP_S3TWISTER_K #define PCI_CHIP_S3TWISTER_K 0x8d02 #endif Does this mean that only "Card:S3 Savage4" is missing from hwdata's pcitable in order to properly autodetect these cards?
https://listman.redhat.com/pipermail/limbo-list/2002-August/002141.html pixel@mandrakesoft.com confirmed that "Card:S3 Savage 4" is the only thing that is missing, preventing Red Hat's XFree86 from autodetecting these two video devices.
I take this back, sorry for the wasted time. While this pcitable change worked fine for the Compaq Presario 700, it failed on the HP ze1210. I guess this driver isn't yet entirely stable. I have tested KM133, PM133, KN133 and PM133, and they all seem fine with Vesa, so I guess this should be DEFERRED for now.
All of these are supported in XFree86 4.3.0 currently. I am considering also backporting this to 4.2.1 and 4.1.0 sometime in the future, however I wont promise anything for sure. Closing as resolved in RAWHIDE.
