With this we can drop the final kfree from the release function. I also noticed that cirrus forgot to call drm_dev_fini(). v2: Don't call kfree(cirrus) after we've handed overship of that to drm_device and the drmm_ stuff. Acked-by:

With this we can drop the final kfree from the release function. The mock device in the selftests needed it's pci_device split up from the drm_device. In the future we could simplify this again by allocating the pci_device as a managed allocation too. v2: I overlooked that i915_driver_destroy is also called in the unwind code of the error path. There we need a drm_dev_put. Similar for the mock object. Now the problem with that is that the drm_driver->release callbacks for both the real driver and the mock one assume everything has been set up. Hence going through that path for a partially set up driver will result in issues. Quickest fix is to disable the ->release() hook until the driver is fully initialized, and keep the onion unwinding. Long term would be cleanest to move everything over to drmm_ release actions, but that's a lot of work for a big driver like i915. Plus more core work needed first anyway. v3: Fix i915_drm pointer wrangling in mock_gem_device. Also switch over to start using drm_dev_put() to clean up even on the error path. Aside I think the current error path is leaking the allocation. v4: more fixes for intel-gfx-ci, some if it damage from v3 :-/ Reviewed-by:

With this we can drop the final kfree from the release function. v2: We need drm_dev_put to unroll the driver creation (once drm_dev_init and drmm_add_final_kfree suceeded), otherwise the drmm_ magic doesn't happen. v3: Actually squash in the fixup (Laurent). Acked-by:

They all share mipi_dbi_release so we need to switch them all together. With this we can drop the final kfree from the release function. Aside, I think we could perhaps have a tiny additional helper for these mipi_dbi drivers, the first few lines around devm_drm_dev_init are all the same (except for the drm_driver pointer). Acked-by:

I also did a full review of all callers, and only the xen driver forgot to call drm_dev_put in the failure path. Fix that up too. v2: I noticed that xen has a drm_driver.release hook, and uses drm_dev_alloc(). We need to remove the kfree from xen_drm_drv_release(). bochs also has a release hook, but leaked the drm_device ever since commit 0a6659bd Author: Gerd Hoffmann <kraxel@redhat.com> Date: Tue Dec 17 18:04:46 2013 +0100 drm/bochs: new driver This patch here fixes that leak.

We have lots of these. And the cleanup code tends to be of dubious quality. The biggest wrong pattern is that developers use devm_, which ties the release action to the underlying struct device, whereas all the userspace visible stuff attached to a drm_device can long outlive that one (e.g. after a hotunplug while userspace has open files and mmap'ed buffers). Give people what they want, but with more correctness. Mostly copied from devres.c, with types adjusted to fit drm_device and a few simplifications - I didn't (yet) copy over everything. Since the types don't match code sharing looked like a hopeless endeavour. For now it's only super simplified, no groups, you can't remove actions (but kfree exists, we'll need that soon). Plus all specific to drm_device ofc, including the logging. Which I didn't bother to make compile-time optional, since none of the other drm logging is compile time optional either. One tricky bit here is the chicken&egg between allocating your drm_device structure and initiliazing it with drm_dev_init. For perfect onion unwinding we'd need to have the action to kfree the allocation registered before drm_dev_init registers any of its own release handlers. But drm_dev_init doesn't know where exactly the drm_device is emebedded into the overall structure, and by the time it returns it'll all be too late. And forcing drivers to be able clean up everything except the one kzalloc is silly. Work around this by having a very special final_kfree pointer. This also avoids troubles with the list head possibly disappearing from underneath us when we release all resources attached to the drm_device. v2: Do all the kerneldoc at the end, to avoid lots of fairly pointless shuffling while getting everything into shape. v3: Add static to add/del_dr (Neil) Move typo fix to the right patch (Neil) v4: Enforce contract for drmm_add_final_kfree: Use ksize() to check that the drm_device is indeed contained somewhere in the final kfree(). Because we need that or the entire managed release logic blows up in a pile of use-after-frees. Motivated by a discussion with Laurent. v5: Review from Laurent: - %zu instead of casting size_t - header guards - sorting of includes - guarding of data assignment if we didn't allocate it for a NULL pointer - delete spurious newline - cast void* data parameter correctly in ->release call, no idea how this even worked before v6: Review from Sam - Add the kerneldoc for the managed sub-struct back in, even if it doesn't show up in the generated html somehow. - Explain why __always_inline. - Fix bisectability around the final kfree() in drm_dev_relase(). This is just interim code which will disappear again. - Some whitespace polish. - Add debug output when drmm_add_action or drmm_kmalloc fail. v7: My bisectability fix wasn't up to par as noticed by smatch. v8: Remove unecessary {} around if else v9: Use kstrdup_const, which requires kfree_const and introducing a free_dr() helper (Thomas). v10: kfree_const goes boom on the plain "kmalloc" assignment, somehow we need to wrap that in kstrdup_const() too!! Also renumber revision log, I somehow reset it midway thruh. Reviewed-by: -

For two reasons: - The driver core clears this already for us after we're unloaded in __device_release_driver(). - It's way too late, the drm_device ->release callback might massively outlive the underlying physical device, since a drm_device can be kept alive by open drm_file or well really anything else userspace is still hanging onto. So if we clear this ourselves, we should clear it in the pci ->remove callback, not in the drm_device ->release callback. Looking at git history this was fixed in the driver core with commit 0998d063 Author: Hans de Goede <hdegoede@redhat.com> Date: Wed May 23 00:09:34 2012 +0200 device-core: Ensure drvdata = NULL when no driver is bound v2: Cite the core fix in the commit message (Chris). v3: Fix commit message and unused variable warning (Jani).

slab does this already, and I want to use this in a memory allocation tracker in drm for stuff that's tied to the lifetime of a drm_device, not the underlying struct device. Kinda like devres, but for drm. Acked-by:

is_color_space_conversion() is a misnomer. It checks not only if color space conversion is needed, but also if format conversion is needed. This is actually desired behaviour because result of this function determines if CSC block should be enabled or not (CSC block can also do format conversion). In order to clear misunderstandings, let's rework is_color_space_conversion() to do exactly what is supposed to do and add another function which will determine if CSC block must be enabled or not.

CEA 861 standard requestis that RGB quantization range is "limited" for CEA modes. Support that by adding CSC matrix which downscales values. This allows proper color reproduction on TV and PC monitor at the same time. In future, override property can be added, like "Broadcast RGB" in i915 driver. Reviewed-by:

Setting scan mode to "none" confuses some TVs like LG B8, which randomly change overscan percentage over time. Digital outputs like HDMI and DVI, handled by this controller, don't really need overscan, so we can always set scan mode to underscan. Actually, this is exactly what drm_hdmi_avi_infoframe_from_display_mode() already does, so we can just remove offending line. Reviewed-by:
