Summary: ioremap leak in DRM
Product: xorg
Version: unspecified
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: minor
Priority: medium
Component: Driver/nouveau
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
QAContact: [EMAIL PROTECTED]
Nouveau is leaking one ioremap per X start. Apparently it is the kernel fifo,
since it always mapped from the beginning of VRAM, and has size 0x8000 or 32kB.
My hardware is NV20 (gf3). DRM and DDX from git around 9th March.
I found this while mmiotracing nouveau. I start the trace, load drm.ko and
nouveau.ko, start X three times in a row, unload nouveau.ko and drm.ko. Now
when I stop mmiotracing, it reports three non-unmapped io-mappings as described
above.
