We'll soon introduce another completion callback source that won't need to use the BO reference counting, so let's move it around to create a function we will be able to share between both callbacks.

On the BCM2711, we currently call the vc4_bo_cache_init() and vc4_gem_init() functions. These functions initialize the BO and GEM backends. However, this code was initially created to accomodate the requirements of the GPU on the older SoCs, while the BCM2711 has a separate driver for it. So let's just skip these calls when we're on a newer hardware.

On the BCM2711, our current definition of drm_plane_helper_funcs uses the custom vc4_prepare_fb() and vc4_cleanup_fb(). Those functions rely on the buffer allocation path that was relying on the GPU, and is no longer relevant. Let's create another drm_plane_helper_funcs structure that we will register on the BCM2711.

Prior to the BCM2711/RaspberryPi4, the GPU was a part of the display components of the SoC. It was thus a part of the vc4 driver. However, with the BCM2711, it got split out and thus the v3d driver was created. The vc4 driver now only handles the display part. We didn't properly split out the code when doing the BCM2711 support though, and most of the code around buffer allocations is still involved, even though it doesn't have the backing hardware anymore. Let's start the split out by creating a new drm_driver that only reports and uses what we support on the BCM2711. The ioctl were properly filtered already, but we were still exposing a .gem_create_object hook, as well as having an .open and .postclose hooks which are only relevant on older generations.

The vc4_bo_dumb_create() both fixes up the allocation arguments to match the hardware constraints and actually performs the allocation. Since we're going to introduce a new function that uses a different allocator, let's split the arguments fixup to a separate function we will be able to reuse.

A new generation of controller has been introduced with the BCM2711/RaspberryPi4. This generation needs a bunch of quirks, and over time we've piled on a number of checks in most parts of the drivers. All these checks are performed several times, and are not always consistent. Let's create a single, global, variable to hold it and use it everywhere.

The vc4 planes are setup in hardware by creating a hardware descriptor in a dedicated RAM. As part of the process to setup a plane in KMS, we thus need to allocate some part of that dedicated RAM to store our descriptor there. The async update path will just reuse the descriptor already allocated for that plane and will modify it directly in RAM to match whatever has been asked for. In order to do that, it will compare the descriptor for the old plane state and the new plane state, will make sure they fit in the same size, and check that only the position or buffer address have changed.

If the component driver fails to bind, or is unbound, the driver data for the top-level platform device points to a freed drm_device. If the system is then suspended, the driver passes this dangling pointer to drm_mode_config_helper_suspend(), which crashes. Fix this by only setting the driver data while the platform driver holds a reference to the drm_device.

It's possible to change which CRTC is in use for a given connector/encoder/bridge while we're in self-refresh without fully disabling the connector/encoder/bridge along the way. This can confuse the bridge encoder/bridge, because (a) it needs to track the SR state (trying to perform "active" operations while the panel is still in SR can be Bad(TM)); and (b) it tracks the SR state via the CRTC state (and after the switch, the previous SR state is lost). Thus, we need to either somehow carry the self-refresh state over to the new CRTC, or else force an encoder/bridge self-refresh transition during such a switch. I choose the latter, so we disable the encoder (and exit PSR) before attaching it to the new CRTC (where we can continue to assume a clean (non-self-refresh) state). This fixes PSR issues seen on Rockchip RK3399 systems with drivers/gpu/drm/bridge/analogix/analogix_dp_core.c. Change in v2: - Drop "->enable" condition; this could possibly be "->active" to reflect the intended hardware state, but it also is a little over-specific. We want to make a transition through "disabled" any time we're exiting PSR at the same time as a CRTC switch.

Most eDP panel functions only work correctly when the panel is not in self-refresh. In particular, analogix_dp_bridge_disable() tends to hit AUX channel errors if the panel is in self-refresh. Given the above, it appears that so far, this driver assumes that we are never in self-refresh when it comes time to fully disable the bridge. Prior to commit 846c7dfc ("drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2."), this tended to be true, because we would automatically disable the pipe when framebuffers were removed, and so we'd typically disable the bridge shortly after the last display activity. However, that is not guaranteed: an idle (self-refresh) display pipe may be disabled, e.g., when switching CRTCs. We need to exit PSR first. Stable notes: this is definitely a bugfix, and the bug has likely existed in some form for quite a while. It may predate the "PSR helpers" refactor, but the code looked very different before that, and it's probably not worth rewriting the fix.

The bluetooth code uses our bitmap infrastructure for the two bits (!) of connection setup flags, and in the process causes odd problems when it converts between a bitmap and just the regular values of said bits. It's completely pointless to do things like bitmap_to_arr32() to convert a bitmap into a u32. It shoudln't have been a bitmap in the first place. The reason to use bitmaps is if you have arbitrary number of bits you want to manage (not two!), or if you rely on the atomicity guarantees of the bitmap setting and clearing. The code could use an "atomic_t" and use "atomic_or/andnot()" to set and clear the bit values, but considering that it then copies the bitmaps around with "bitmap_to_arr32()" and friends, there clearly cannot be a lot of atomicity requirements. So just use a regular integer. In the process, this avoids the warnings about erroneous use of bitmap_from_u64() which were triggered on 32-bit architectures when conversion from a u64 would access two words (and, surprise, surprise, only one word is needed - and indeed overkill - for a 2-bit bitmap). That was always problematic, but the compiler seems to notice it and warn about the invalid pattern only after commit 0a97953f ("lib: add bitmap_{from,to}_arr64") changed the exact implementation details of 'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

Note that this currently supports only one provider, but there seems to be enough interest in this functionality and we expect to see more drivers added once this is merged" [ Linus Walleij mentions the Intel PMC in the Elkhart and Tiger Lake platforms as another future timestamp provider ] * tag 'hte/for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: dt-bindings: timestamp: Correct id path dt-bindings: Renamed hte directory to timestamp hte: Uninitialized variable in hte_ts_get() hte: Fix off by one in hte_push_ts_ns() hte: Fix possible use-after-free in tegra_hte_test_remove() hte: Remove unused including <linux/version.h> MAINTAINERS: Add HTE Subsystem hte: Add Tegra HTE test driver tools: gpio: Add new hardware clock type gpiolib: cdev: Add hardware timestamp clock type gpio: tegra186: Add HTE support gpiolib: Add HTE support dt-bindings: Add HTE bindings hte: Add Tegra194 HTE kernel provider drivers: Add hardware timestamp engine (HTE) subsystem Documentation: Add HTE subsystem guide

Pull mount handling updates from Al Viro: "Cleanups (and one fix) around struct mount handling. The fix is usermode_driver.c one - once you've done kern_mount(), you must kern_unmount(); simple mntput() will end up with a leak. Several failure exits in there messed up that way... In practice you won't hit those particular failure exits without fault injection, though" * tag 'pull-18-rc1-work.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: move mount-related externs from fs.h to mount.h blob_to_mnt(): kern_unmount() is needed to undo kern_mount() m->mnt_root->d_inode->i_sb is a weird way to spell m->mnt_sb... linux/mount.h: trim includes uninline may_mount() and don't opencode it in fspick(2)/fsopen(2)
