           Summary: [NVA5] Created FIFOs do not work
           Product: xorg
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org

Created an attachment (id=50104)
 --> (https://bugs.freedesktop.org/attachment.cgi?id=50104)
kernel log with drm.debug=15

I must currently use 'noaccel=1' to use nouveau on my NVA5 (GT 220, 1GB vram).

While debugging, it appeared the extra created FIFOs simply do not run at all,
and trigger PFIFO_DMA_PUSHER errors, with IB_EMPTY status. The first of these
errors happen in nouveau_dma_init() function, which is the first one to be run
after creation of a new FIFO.

I must add 'vram_pushbuf=1' to kernel parameters to not have these errors at
start, however, adding 'vram_notify=1' appears to have not effect.

X crashes at start if I do not use 'noaccel=1', with or without
'vram_pushbuf=1', triggering PFIFO_DMA_PUSHER errors, with INVALID_CMD status.
