[PATCH 1/6] drm/nouveau: bo read/write wrappers for nv04_crtc.c
Introduce accessors for TTM buffer object memory that has been mapped into the kernel virtual address space or as IO memory. IO memory needs to be accessed via special accessor functions, not by dereferencing the iomem cookie. The wrappers hide the details of 32-bit access and honour the TTM map type. nv04_crtc_cursor_set() is changed to use the new wrappers. 'cursor' is received from

[PATCH] drm/nouveau: rewrite nouveau_dma_wait()
From: Ben Skeggs <bskeggs at redhat.com> There was at least one situation we could get into in the old code where we'd end up overrunning the push buffer with the jumps back to the start of the buffer in an attempt to get more space. In addition, the new code prevents misdetecting a GPU hang by resetting the timeout counter if we see the GPU GET pointer advancing, and simplifies the

[RFC] patch 0/4: DRM MMIO accessor cleanup
Hi, this is continuation for the MMIO accessor rewrite and cleanup. I am currently running nv28 with these patches applied, but I cannot test on PPC. Please, review and comment. If the direction is good, I'll do the same to INSTANCE_{RD,WR} as I did for nv_{rd,wr}32, and change PRAMIN from drm_local_map to simple ioremap. Can the same be done for channel specific mappings, that is

[PATCH 1/3] Introduce nouveau_bo_wait for waiting on a BO with a GPU channel
nouveau_bo_wait will make the GPU channel wait for fence if possible, otherwise falling back to waiting with the CPU using ttm_bo_wait. The nouveau_fence_sync function currently returns -ENOSYS, and is the focus of the next patch.

[PATCH] drm/nouveau: don't hold spin lock while calling kzalloc with GFP_KERNEL
- 'joi' on irc pointed out that this triggers a BUG_ON, because kzalloc could sleep. - The irq handler should restore the value NV03_PFIFO_CACHES, but still it's better if this stuff doesn't happen in the middle of fifo create context. I see no reason in spin locking pgraph create context, it isn't activated at that stage. - Move and rename the lock after some discussion with

[PATCH drm-misc-next v2] drm/nouveau: uapi: don't pass NO_PREFETCH flag implicitly
Currently, NO_PREFETCH is passed implicitly through drm_nouveau_gem_pushbuf_push::length and drm_nouveau_exec_push::va_len. Since this is a direct representation of how the HW is programmed it isn't really future proof for a uAPI. Hence, fix this up for the new uAPI and split up the va_len field of struct drm_nouveau_exec_push, such that we keep 32bit for va_len and 32bit for flags. For

[PATCH 10/10] drm/nouveau: fix off-by-one bugs related to command submission in IB mode
Commit "drm/nouveau: port all engines to new engine module format" changed IB size calculation to be less wasteful, but didn't take into account already existing off-by-one bugs :). So: - ib_max is the last entry, so we need to +1 when calculating number of free entries - nv50_dma_wait already does +1 (for FIRE_RING), so we don't need another +1 on nouveau_gem_ioctl_pushbuf
