In order to support driver hot unbind, some cleanup operations, now performed on PCI driver remove, must be called later, after all device file descriptors are closed. Split out those operations from the tail of pci_driver.remove() callback and put them into drm_driver.release() which is called as soon as all references to the driver are put. As a result, those cleanups will be now run on last drm_dev_put(), either still called from pci_driver.remove() if all device file descriptors are already closed, or on last drm_release() file operation.

The plan is to use the blitter engine for async object clearing when using local memory, but before we can move the worker to get_pages() we have to first tame some more of our struct_mutex usage. With this in mind we should be able to upstream the object clearing as some selftests, which should serve as a guinea pig for the ongoing locking rework and upcoming async get_pages() framework.

Some steps in gen6_alloc_va_range require the HW to be awake, so ideally we should be grabbing the wakeref ourselves and not relying on the caller already holding it for us. Suggested-by:

An interesting issue cropped with making the pagetables be allocated and freed concurrently (i.e. removing their grandeous struct_mutex guard) was that we would overflow the page stash. This happens when we have multiple allocators grabbing WC pages such that we fill the vm's local page stash and then when we free another page, the page stash is already full and we overflow. The fix is quite simple: to check for a full page stash before adding another. This results in us keeping a vm local page stash around for much longer, which is both a blessing and a curse.

This reverts commit 1ac159e2 ("drm/i915: Expand subslice mask"), which kills ICL due to GEM_BUG_ON() sanity checks before CI even gets a chance to do anything. The commit exposes an issue in commit 1e40d4ae ("drm/i915/cnl: Implement WaProgramMgsrForCorrectSliceSpecificMmioReads"), which will also need to be addressed. There's a proposed fix [1], but considering the seeming uncertainty with the fix as well as the size of the regressing commit (in this context, the one that actually brings down ICL), this warrants a revert to get ICL working, and gives us time to get all of this right without rushing. Even if this means shooting the messenger. <3>[ 9.426327] intel_sseu_get_subslices:46 GEM_BUG_ON(slice >= sseu->max_slices) <4>[ 9.426355] ------------[ cut here ]------------ <2>[ 9.426357] kernel BUG at drivers/gpu/drm/i915/gt/intel_sseu.c:46! <4>[ 9.426371] invalid opcode: 0000 [#1] PREEMPT SMP NOPTI <4>[ 9.426377] CPU: 1 PID: 364 Comm: systemd-udevd Not tainted 5.2.0-rc2-CI-CI_DRM_6159+ #1 <4>[ 9.426385] Hardware name: Intel Corporation Ice Lake Client Platform/IceLake U DDR4 SODIMM PD RVP TLC, BIOS ICLSFWR1.R00.3183.A00.1905020411 05/02/2019 <4>[ 9.426444] RIP: 0010:intel_sseu_get_subslices+0x8a/0xe0 [i915] <4>[ 9.426452] Code: d5 76 b7 e0 48 8b 35 9d 24 21 00 49 c7 c0 07 f0 72 a0 b9 2e 00 00 00 48 c7 c2 00 8e 6d a0 48 c7 c7 a5 14 5b a0 e8 36 3c be e0 <0f> 0b 48 c7 c1 80 d5 6f a0 ba 30 00 00 00 48 c7 c6 00 8e 6d a0 48 <4>[ 9.426468] RSP: 0018:ffffc9000037b9c8 EFLAGS: 00010282 <4>[ 9.426475] RAX: 000000000000000f RBX: 0000000000000000 RCX: 0000000000000000 <4>[ 9.426482] RDX: 0000000000000001 RSI: 0000000000000008 RDI: ffff88849e346f98 <4>[ 9.426490] RBP: ffff88848a200000 R08: 0000000000000004 R09: ffff88849d50b000 <4>[ 9.426497] R10: 0000000000000000 R11: ffff88849e346f98 R12: ffff88848a209e78 <4>[ 9.426505] R13: 0000000003000000 R14: ffff88848a20b1a8 R15: 0000000000000000 <4>[ 9.426513] FS: 00007f73d5ae8680(0000) GS:ffff88849fc80000(0000) knlGS:0000000000000000 <4>[ 9.426521] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 <4>[ 9.426527] CR2: 0000561417b01260 CR3: 0000000494764003 CR4: 0000000000760ee0 <4>[ 9.426535] PKRU: 55555554 <4>[ 9.426538] Call Trace: <4>[ 9.426585] wa_init_mcr+0xd5/0x110 [i915] <4>[ 9.426597] ?

In intel_wakeref_auto, we use refcount_inc_not_zero to detect the first use and initialise the timer. On doing so, we have to avoid using refcount_inc on that zero count as the debug code flags that as an error: refcount_t: increment on 0; use-after-free. Rearrange the code so that if we know the count is 0 and we are initialising, we explicitly set it to 1. Fixes: b27e35ae ("drm/i915: Keep user GGTT alive for a minimum of 250ms") Signed-off-by:
