[Nouveau] [Bug 56202] New: [regression][kms] Clock rework causes kms boot regression for NV4E (v3.7-rc1, 3.6+nouveau)
https://bugs.freedesktop.org/show_bug.cgi?id=56202 Priority: medium Bug ID: 56202 Assignee: nouveau at lists.freedesktop.org Summary: [regression][kms] Clock rework causes kms boot regression for NV4E (v3.7-rc1, 3.6+nouveau) QA Contact: xorg-team at lists.x.org Severity: normal Classification: Unclassified OS: Linux (All) Reporter: ronald645 at gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Driver/nouveau Product: xorg Created attachment 68815 --> https://bugs.freedesktop.org/attachment.cgi?id=68815&action=edit v3.6.0+ @ the commit that caused the regression The following commit causes KMS initialisation to result in a scrambled screen with mostly blue elements. The screen responds to changes based on actual content (e.g. system booting, lightdm starting). drm/nouveau/clock: pull in the implementation from all over the place I have tested and verified this regression on a 3.6 tree and the recent v3.7 tree pulled from git.kernel.org. Below you will find some more data about my VGA card. Attached you will find two dmesg output logs (don't know if they differ): both are from the v3.7-rc1 tree (they are noted as 3.6.0+ in the logs) dmesg-good.txt @ the commit before the one that caused the regression dmesg-bad.txt @ the commit that caused the regression 00:05.0 0300: 10de:0244 (rev a2) (prog-if 00 [VGA controller]) Subsystem: 103c:30b7 00:05.0 VGA compatible controller: NVIDIA Corporation C51 [GeForce Go 6150] (rev a2) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Presario V6133CL Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 Interrupt: pin A routed to IRQ 18 Region 0: Memory at b2000000 (32-bit, non-prefetchable) [size=16M] Region 1: Memory at c0000000 (64-bit, prefetchable) [size=256M] Region 3: Memory at b1000000 (64-bit, non-prefetchable) [size=16M] [virtual] Expansion ROM at 40000000 [disabled] [size=128K] Capabilities: [48] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Capabilities: [50] MSI: Enable- Count=1/1 Maskable- 64bit+ Address: 0000000000000000 Data: 0000 Kernel driver in use: nouveau -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...

https://bugs.freedesktop.org/show_bug.cgi?id=56202 --- Comment #2 from Ronald <ronald645 at gmail.com> --- I guess this just turned pretty obvious, I took another look at both the dmesg output of both kernels. Good kernel says: +[drm] nouveau 0000:00:05.0: c: Bad kernel says: -[drm] nouveau 0000:00:05.0: c: core 24MHz That is not a typo! -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
