2012-10-03drm/nouveau: port all engines to new engine module formatBen Skeggs
This is a HUGE commit, but it's not nearly as bad as it looks - any problems can be isolated to a particular chipset and engine combination. It was simply too difficult to port each one at a time, the compat layers are *already* ridiculous. Most of the changes here are simply to the glue, the process for each of the engine modules was to start with a standard skeleton and copy+paste the old code into the appropriate places, fixing up variable names etc as needed. v2: Marcin Slusarz <marcin.slusarz@gmail.com> - fix find/replace bug in license header v3: Ben Skeggs <bskeggs@redhat.com> - bump indirect pushbuf size to 8KiB, 4KiB barely enough for userspace and left no space for kernel's requirements during GEM pushbuf submission. - fix duplicate assignments noticed by clang v4: Marcin Slusarz <marcin.slusarz@gmail.com> - add sparse annotations to nv04_fifo_pause/nv04_fifo_start - use ioread32_native/iowrite32_native for fifo control registers v5: Ben Skeggs <bskeggs@redhat.com> - rebase on v3.6-rc4, modified to keep copy engine fix intact - nv10/fence: unmap fence bo before destroying - fixed fermi regression when using nvidia gr fuc - fixed typo in supported dma_mask checking Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-10-03drm/nvc0-/gr: share headers between fermi and kepler graphics codeBen Skeggs
v2: Ben Skeggs <bskeggs@redhat.com> - de-inline nv_icmd, triggers some gcc issue causing ctxnv[ce]0.c to take a *very* *very* long time to build on some configs. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nouveau/pageflip: kick flip handling out of engsw and into fenceBen Skeggs
This is all very much a policy thing, and hence will not belong in SW after the rework. engsw now only handles receiving the event to say "can flip now" and makes a callback to perform the actual work. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-10-03drm/nvc0-nve0/graph: rename dev to priv, no code changesBen Skeggs
There's a *lot* of code in here, and it's all going to use the PGRAPH priv pointer rather than drm_device after the engine rework. This is handling all the rename-only parts of the change. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nouveau/fence: un-port from nouveau_exec_engine interfacesBen Skeggs
Still the same code, but not an "engine" anymore. The fence code is more of a policy decision rather than exposing mechanisms, so it's not appropriate to port it to the new engine subsystem. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-10-03drm/nouveau/gpuobj: remove flags for vm-mappingsBen Skeggs
Having GPUOBJ and VM intertwined like this makes it *really* hard to continue porting to the new driver architecture, split it out in favour of requiring explit maps be the caller. It's more flexible and obvious this way anyway... Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-10-03drm/nv04-nv40/instmem: duplicate nv04 code as nv40, remove alternate pathsBen Skeggs

2012-10-03drm/nouveau: have non-core mmio accesses go through device objectBen Skeggs
Adds an extra layer of indirection to each register access, but it's not too bad, and will also go away as pieces are ported. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nouveau: implement module init functions in nouveau_drm.cBen Skeggs
These currently just call the existing ones in nouveau_drv.c, but will be extended in upcoming commits. This needed to be separated from the current code as there will be some header clashes until things are ported. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nouveau/core: pull in most of the new core infrastructureBen Skeggs
This commit provides most of the infrastructure to support a major overhaul of Nouveau's internals coming in the following commits. This work aims to take all the things we've learned over the last several years, and turn that into a cleaner architecture that's more maintainable going forward. RAMHT and MM bits of the new core have been left out for the moment, and will be pulled in as I go through the process of porting the code to become either subdev or engine modules. There are several main goals I wanted to achieve through this work: -- Reduce complexity The goal here was to make each component of the driver as independent as possible, which will ease maintainability and readability, and provide a good base for resetting locked up GPU units in the future. -- Better tracking of GPU units that are required at any given time This is for future PM work, we'll be able to tell exactly what parts of the GPU we need powered at any given point (etc). -- Expose all available NVIDIA GPUs to the client In order to support things such as multi-GPU channels, we want to be able to expose all the NVIDIA GPUs to the client over a single file descriptor so it can send a single push buffer to multiple GPUs. -- Untangle the core hardware support code from the DRM implementation This happened initially as an unexpected side-effect of developing the initial core infrastructure in userspace, but it turned into a goal of the whole project. Initial benefits will be the availablility of a number of userspace tools and tests using the same code as the driver itself, but will also be important as I look into some virtualisation ideas. v2: Ben Skeggs <bskeggs@redhat.com> - fix duplicate assignments noticed by clang - implement some forgotten yelling in error path - ensure 64-bit engine mask is used everywhere v3: Marcin Slusarz <marcin.slusarz@gmail.com> - sparse fixes - inline nv_printk into nv_assert to prevent recursive inlining issues v4: Ben Skeggs <bskeggs@redhat.com> - fixed minor memory leak on gpuobj destruction Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-10-03drm/nouveau: restructure source tree, split core from drm implementationBen Skeggs
Future work will be headed in the way of separating the policy supplied by the nouveau drm module from the mechanisms provided by the driver core. There will be a couple of major classes (subdev, engine) of driver modules that have clearly defined tasks, and the further directory structure change is to reflect this. No code changes here whatsoever, aside from fixing up a couple of include file pathnames. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nouveau/gem: use bo.offset rather than mm_node.startBen Skeggs
Won't necessarily be a drm_mm_node in the future, and I can't think of any good reason to not use the offset from the bo struct. There may have been some reason once apon a time, but, separate commit just in case. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-10-03drm/nvc0/fence: restore pre-suspend fence buffer context on resumeBen Skeggs
Fixes some unfortunate races on resume. The G84 version of the code doesn't need this as "gpuobj"s are automagically suspended/resumed by the core code whereas pinned buffer objects are not. Cc: stable@vger.kernel.org Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-10-02compat: fs: Generic compat_sys_sendfile implementationCatalin Marinas
This function is used by sparc, powerpc and arm64 for compat support. The patch adds a generic implementation which calls do_sendfile() directly and avoids set_fs(). The sparc architecture has wrappers for the sign extensions while powerpc relies on the compiler to do the this. The patch adds wrappers for powerpc to handle the u32->int type conversion. compat_sys_sendfile64() can be replaced by a sys_sendfile() call since compat_loff_t has the same size as off_t on a 64-bit system. On powerpc, the patch also changes the 64-bit sendfile call from sys_sendile64 to sys_sendfile. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Acked-by: David S.

2012-10-02fs: push rcu_barrier() from deactivate_locked_super() to filesystemsKirill A. Shutemov
There's no reason to call rcu_barrier() on every deactivate_locked_super(). We only need to make sure that all delayed rcu free inodes are flushed before we destroy related cache. Removing rcu_barrier() from deactivate_locked_super() affects some fast paths. E.g. on my machine exit_group() of a last process in IPC namespace takes 0.07538s. rcu_barrier() takes 0.05188s of that time. Signed-off-by: Kirill A.
