* drm: Use static attribute groups for managing connector sysfs entriesTakashi Iwai2015-02-041-65/+67
| | | | | | | | | | | | Instead of manual calls of device_create_file() and device_remove_file(), assign the static attribute groups to the device with device_create_with_groups(). The conditionally built sysfs entries are handled via is_visible callback. This simplifies the code and also avoids the possible races.

| | | | | | | | | | This way drivers can't grow crazy ideas any more, and it also helps a bit in reviewing EXPORT_SYMBOLS. v2: Even more stuff. Unfortunately we can't move drm_vm_open_locked because exynos does some horrible stuff with it. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
* drm: make sysfs device always available for minorsDavid Herrmann2014-08-051-53/+37
| | | | | | | | | | | | | | | | | For each minor we allocate a sysfs device as minor->kdev. Currently, this is allocated and registered in drm_minor_register(). This makes it impossible to add sysfs-attributes to the device before it is registered. Therefore, they are not added atomically, nor can we move device_add() *after* ->load() is called. This patch makes minor->kdev available early, but only adds the device during minor-registration. Note that the registration is still called before ->load() as debugfs needs to be split, too. This will be fixed in follow-ups. Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: David Herrmann <dh.herrmann@gmail.com>

* drm/sysfs: fix hotplug regression since lifetime changesDavid Herrmann2013-11-211-7/+33
| | | | | | | | | | | | airlied: The lifetime changes introduced in 5bdebb183c9702a8c57a01dff09337be3de337a6 tried to use device_create, however that led to the regression where dev->type wasn't getting set correctly. First attempt at fixing it would have led to a race, so this undoes the device_createa work and does it all manually making sure the dev->type is setup before we register the device.

* drm/sysfs: sort out minor and connector device object lifetimes.Dave Airlie2013-10-221-60/+34
| | | | | | | | | | | | | | | | | So drm was abusing device lifetimes, by having embedded device structures in the minor and connector it meant that the lifetime of the internal drm objects (drm_minor and drm_connector) were tied to the lifetime of the device files in sysfs, so if something kept those files opened the current code would kfree the objects and things would go downhill from there. Now in reality there is no need for these lifetimes to be so intertwined, especailly with hotplugging of devices where we wish to remove the sysfs and userspace facing pieces before we can unwind the internal objects due to open userspace files or mmaps, so split the objects out so the struct device is no longer embedded and do what fbdev does and just allocate and remove the sysfs inodes separately.

* drm: Convert drm class driver from legacy pm ops to dev_pm_opsShuah Khan2013-07-041-4/+29
| | | | | | | | | | | | | | | | | | | | | | Convert drivers/gpu/drm class to use dev_pm_ops for power management and remove Legacy PM ops hooks. With this change, drm class registers suspend/resume callbacks via class->pm (dev_pm_ops) instead of Legacy class->suspend/resume. When __device_suspend() runs call-backs, it will find class->pm ops for the drm class. drm_class_suspend() hook calls driver legacy ops with the state information. e.g: drm_class_suspend() calls into driver suspend routines via drm_dev->driver->suspend(drm_dev, state). Once drm_class_suspend() is converted to dev_pm_ops, it will no longer have access to pm_transition which it has to pass into driver legacy suspend calls. A new freeze and suspend hooks are added to address the not having access to the state information. The new freeze and suspend hooks simply call __drm_class_suspend() with the appropriate pm state information. __drm_class_suspend() is the original suspend hook with a new name.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As detect will use hw registers and may modify structures, it needs to be serialised by use of the dev->mode_config.mutex.

* / include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 allows subsytems to provide devtmpfs with non-default permissions for the device node. Instead of the default mode of 0600, null, zero, random, urandom, full, tty, ptmx now have a mode of 0666, which allows non-privileged processes to access standard device nodes in case no other userspace process applies the expected permissions.

| | | | | | | | | | | | | | | | In current code we register/unregister connector object by drm_sysfs_connector_add/remove function. However under some cases, we need to dynamically register or unregister device multiple times, so we have to go through register -> unregister ->register routine. Because after device_unregister function our memory is dirty, we need to do clean operation in order to re-register the device, otherwise the system will crash. The patch intends to clean device after device release. Signed-off-by: Ma Ling <ling.ma@intel.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel shouldn't be in the business of telling user space which driver to load. The kernel defers mapping PCI IDs to module names to user space and we should do the same for DRI drivers. And in fact, that's how it does work today. Nothing uses the dri_library_name attribute, and the attribute is in fact broken. For intel devices, it falls back to the default behaviour of returning the kernel module name as the DRI driver name, which doesn't work for i965 devices. Nobody has ever hit this problem or filed a bug about this. Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Dave Airlie <airlied@linux.ie>

|/ | | | | | | | | | Under kernel modesetting, we manage the device at all times, regardless of VT switching and X servers, so the only decent thing to do is to claim the PCI device. In that case, we call the suspend/resume hooks directly from the pci driver hooks instead of the current class device detour.
