Sigh. Since nv50_msto_atomic_check() has broken a few times now, let's rethink things a bit to be more careful: limit both VCPI/PBN allocations to mode_changed || connectors_changed, since neither VCPI or PBN should ever need to change outside of routing and mode changes.

This seems like it could be OK, but casues problems if a suspend gets interrupted partway through. The OS only balances matching suspend/resume levels. ...so if suspend was called then resume will be called. If suspend late was called then resume early will be called. ...but if suspend was called resume early might not get called. This leads to an unbalance in the clock enables / disables. Lets take the simple fix and just move suspend to be late to match. This makes the PM core take proper care in keeping things balanced.

So it can not display the framebuffer console because the respective buffer object is permanently pinned in system memory. Using a shadow buffer for the console solves this problem. The console emulation will pin the buffer object only during updates from the shadow buffer.

The buffer, like any buffer object, should be mapped and unmapped when needed. An unmapped buffer object can be evicted to system memory and does not consume video ram until displayed. This allows to use generic fbdev emulation with drivers for low-memory devices, such as ast and mgag200. This change affects the generic framebuffer console. HW-based consoles map their console buffer once and keep it mapped. Userspace can mmap this buffer into its address space. The shadow-buffered framebuffer console only needs the buffer object to be mapped during updates. While not being updated from the shadow buffer, the buffer object can remain unmapped. Userspace will always mmap the shadow buffer. v2: * change DRM client to not map buffer by default * manually map client buffer for fbdev with HW framebuffer Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/315830/ Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

Mapping a buffer implicitly prevents its relocation. Hence, the buffer may permanently consume video memory while it's allocated. This is a problem for drivers of low-memory devices, such as ast, mgag200 or older framebuffer hardware, which will then not have enough memory to display other content (e.g., X11). This patch introduces drm_client_buffer_vmap() and _vunmap(). Internal DRM clients can use these functions to unmap and remap buffer objects as needed. There's no reference counting for vmap operations. Callers are expected to either keep buffers mapped (as it is now), or call vmap and vunmap in pairs around code that accesses the mapped memory. v2: * remove several duplicated NULL-pointer checks v3: * style and typo fixes Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/315831/ Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

This is useful to excise a linkage between reset and the shrinker. When waking the engine, we need to pin the default context image which we use for overwriting a guilty context -- if the engine is idle we do not need this pinned image! However, this pinning means that waking the engine acquires the FS_RECLAIM, and so may trigger the shrinker. The shrinker itself may need to wait upon the GPU to unbind and object and so may require services of reset; ergo we should avoid the engine wake up path. The danger in skipping the recovery for idle engines is that we leave the engine with no context defined, which may interfere with the operation of the power context on some older platforms. In practice, we should only be resetting an active GPU but it something to look out for on Ironlake (if memory serves).
