2011-04-20drm/nouveau: fix notifier memory corruption bugMarcin Slusarz
nouveau_bo_wr32 expects offset to be in words, but we pass value in bytes, so after commit 73412c3854c877e5f37ad944ee8977addde4d35a ("drm/nouveau: allocate kernel's notifier object at end of block") we started to overwrite some memory after notifier buffer object (previously m2mf_ntfy was always 0, so it didn't matter it was a value in bytes).

2011-02-25drm/nouveau: remove no_vm/mappable flags from nouveau_boBen Skeggs
'mappable' isn't really used at all, nor is it necessary anymore as the bo code is capable of moving buffers to mappable vram as required. 'no_vm' isn't necessary anymore either, any places that don't want to be mapped into a GPU address space should allocate the VRAM directly instead. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-12-21drm/fb: Don't expose mmio for fbdev emulation layerJames Simmons
For the fbdev api if the struct fb_var_screeninfo accel_flags field is set to FB_ACCELF_TEXT then userland applications can not mmap the mmio region. Since it is a bad idea for DRM drivers to expose the mmio region via the fbdev layer we always set the accel_flags to prevent this. Please apply.

2010-12-03drm/nouveau: add per-channel mutex, use to lock access to drm's channelBen Skeggs
This fixes a race condition between fbcon acceleration and TTM buffer moves. To reproduce: - start X - switch to vt and "while (true); do dmesg; done" - switch to another vt and "sleep 2 && cat /path/to/debugfs/dri/0/evict_vram" - switch back to vt running dmesg We don't make use of this on any other channel yet, they're currently protected by drm_global_mutex.

2010-12-03drm/nouveau: disallow fbcon accel if running in interrupt contextBen Skeggs
A future commit will add locking to the DRM's channel, and there's numerous problems that come up if we allow printk from an interrupt context to be accelerated. It seems saner to just disallow it completely. As a nice side-effect, all the "to accel or not to accel" logic gets moved out of the chipset-specific code.

2010-10-01drm/gem: handlecount isn't really a kref so don't make it one.Dave Airlie
There were lots of places being inconsistent since handle count looked like a kref but it really wasn't. Fix this my just making handle count an atomic on the object, and have it increase the normal object kref. Now i915/radeon/nouveau drivers can drop the normal reference on userspace object creation, and have the handle hold it. This patch fixes a memory leak or corruption on unload, because the driver had no way of knowing if a handle had been actually added for this object, and the fbcon object needed to know this to clean itself up properly.

2010-08-10vt/console: try harder to print output when panicingJesse Barnes
Jesse's initial patch commit said: "At panic time (i.e. when oops_in_progress is set) we should try a bit harder to update the screen and make sure output gets to the VT, since some drivers are capable of flipping back to it. So make sure we try to unblank and update the display if called from a panic context." I've enhanced this to add a flag to the vc that console layer can set to indicate they want this behaviour to occur. This also adds support to fbcon for that flag and adds an fb flag for drivers to indicate they want to use the support. It enables this for KMS drivers.

This patch is against the drm-fbdevfix1 branch. It removes the drm_fb_helper_setcolreg function. The reason is that fb_setcolreg is only used in the case where fb_setcmap is called and no fb_ops->fb_setcmap is used.

This patch a) removes the info pointer/psuedo palette from the core drm_framebuffer structure and moves it to the fbdev helper layer, it also removes the core drm keeping a list of kernel kms fbdevs. b) migrated all the fb helper functions out of the crtc helper file into the fb helper file. c) pushed the fb probing/hotplug control into the driver d) makes the surface sizes into a structure for ease of passing This changes the intel/radeon/nouveau drivers to use the new helper.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA. This driver is a KMS-based driver and requires a compatible nouveau userspace libdrm and nouveau X.org driver.

This driver is reverse engineered, and is in no way supported by nVidia.
