If WOPCM layout is already locked in HW we shouldn't continue with our own partitioning as it could be likely different and we will be unable to enforce it and fail. Instead we should try to reuse what is already programmed, maybe there will be a fit.

2019-08-15drm/i915/gt: Guard timeline pinning without relying on struct_mutexChris Wilson
In preparation for removing struct_mutex from around context retirement, we need to make timeline pinning and unpinning safe. Since multiple engines/contexts can share a single timeline, we cannot rely on borrowing the context mutex (otherwise we could state that the timeline is only pinned/unpinned inside the context pin/unpin and so guarded by it). However, we only perform a sequence of atomic operations inside the timeline pin/unpin and the sequence of those operations is safe for a concurrent unpin / pin, so we can relax the struct_mutex requirement.

2019-08-14drm/i915: Serialise read/write of the barrier's engineChris Wilson
We use the request pointer inside the i915_active_node as the indicator of the barrier's status; we mark it as used during i915_request_add_active_barriers(), and search for an available barrier in reuse_idle_barrier(). That check must be carefully serialised to ensure we do use an engine for the barrier and not just a random pointer. (Along the other reuse path, we are fully serialised by the timeline->mutex.) The acquisition of the barrier itself is ordered through the strong memory barrier in llist_del_all().

2019-08-14drm/i915: Disregard drm_mode_config.fb_baseChris Wilson
The fb_base is only used for communicating the GTT BAR from one piece of the display code (kms setup) to another (fbdev). What is required in the fbdev is just the aperture address which should be derived from the bo we allocate for the framebuffer directly. The same appears true for drm/; it is not used by the core or the uAPI, it is merely for conveniently passing a device address from bit of display management code to another. v2: Note that since we only expose enough of a system map to cover our single framebuffer, the screen_base/size and the smem are one and the same.

2019-08-13drm/i915: Push the wakeref->count deferral to the backendChris Wilson
If the backend wishes to defer the wakeref parking, make it responsible for unlocking the wakeref (i.e. bumping the counter). This allows it to time the unlock much more carefully in case it happens to needs the wakeref to be active during its deferral. For instance, during engine parking we may choose to emit an idle barrier (a request). To do so, we borrow the engine->kernel_context timeline and to ensure exclusive access we keep the engine->wakeref.count as 0. However, to submit that request to HW may require a intel_engine_pm_get() (e.g. to keep the submission tasklet alive) and before we allow that we have to rewake our wakeref to avoid a recursive deadlock. <4> [257.742916] IRQs not enabled as expected <4> [257.742930] WARNING: CPU: 0 PID: 0 at kernel/softirq.c:169 __local_bh_enable_ip+0xa9/0x100 <4> [257.742936] Modules linked in: vgem snd_hda_codec_hdmi snd_hda_codec_realtek snd_hda_codec_generic i915 btusb btrtl btbcm btintel snd_hda_intel snd_intel_nhlt bluetooth snd_hda_codec coretemp snd_hwdep crct10dif_pclmul snd_hda_core crc32_pclmul ecdh_generic ecc ghash_clmulni_intel snd_pcm r8169 realtek lpc_ich prime_numbers i2c_hid <4> [257.742991] CPU: 0 PID: 0 Comm: swapper/0 Tainted: G U W 5.3.0-rc3-g5d0a06cd532c-drmtip_340+ #1 <4> [257.742998] Hardware name: GIGABYTE GB-BXBT-1900/MZBAYAB-00, BIOS F6 02/17/2015 <4> [257.743008] RIP: 0010:__local_bh_enable_ip+0xa9/0x100 <4> [257.743017] Code: 37 5b 5d c3 8b 80 50 08 00 00 85 c0 75 a9 80 3d 0b be 25 01 00 75 a0 48 c7 c7 f3 0c 06 ac c6 05 fb bd 25 01 01 e8 77 84 ff ff <0f> 0b eb 89 48 89 ef e8 3b 41 06 00 eb 98 e8 e4 5c f4 ff 5b 5d c3 <4> [257.743025] RSP: 0018:ffffa78600003cb8 EFLAGS: 00010086 <4> [257.743035] RAX: 0000000000000000 RBX: 0000000000000200 RCX: 0000000000010302 <4> [257.743042] RDX: 0000000080010302 RSI: 0000000000000000 RDI: 00000000ffffffff <4> [257.743050] RBP: ffffffffc0494bb3 R08: 0000000000000000 R09: 0000000000000001 <4> [257.743058] R10: 0000000014c8f0e9 R11: 00000000fee2ff8e R12: ffffa23ba8c38008 <4> [257.743065] R13: ffffa23bacc579c0 R14: ffffa23bb7db0f60 R15: ffffa23b9cc8c430 <4> [257.743074] FS: 0000000000000000(0000) GS:ffffa23bbba00000(0000) knlGS:0000000000000000 <4> [257.743082] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 <4> [257.743089] CR2: 00007fe477b20778 CR3: 000000011f72a000 CR4: 00000000001006f0 <4> [257.743096] Call Trace: <4> [257.743104] <IRQ> <4> [257.743265] __i915_request_commit+0x240/0x5d0 [i915] <4> [257.743427] ? __i915_request_create+0x228/0x4c0 [i915] <4> [257.743584] __engine_park+0x64/0x250 [i915] <4> [257.743730] ____intel_wakeref_put_last+0x1c/0x70 [i915] <4> [257.743878] i915_sample+0x2ee/0x310 [i915] <4> [257.744030] ? i915_pmu_cpu_offline+0xb0/0xb0 [i915] <4> [257.744040] __hrtimer_run_queues+0x11e/0x4b0 <4> [257.744068] hrtimer_interrupt+0xea/0x250 <4> [257.744079] ? lockdep_hardirqs_off+0x79/0xd0 <4> [257.744101] smp_apic_timer_interrupt+0x96/0x280 <4> [257.744114] apic_timer_interrupt+0xf/0x20 <4> [257.744125] RIP: 0010:__do_softirq+0xb3/0x4ae v2: Keep the priority_hint assert v3: That assert was desperately trying to point out my bug.

2019-08-13drm/i915/gvt: factor out tlb and mocs register offset tableZhi Wang
Factor out tlb and mocs register offset table to fix the issues reported by klocwork, #512 and #550. Mostly, the reason why the klocwork reports these problems is because there can be possbilities for platforms, which have more rings than the ring offset table, to take the dirty data from the stack as the register offset. It results to a random HW register offset writting in this scenairo when doing context switch between vGPUs. After the factoring, the ring offset table of TLB and MOCS should be per platform. v2: - Enable TLB register switch for GEN8.

2019-08-13drm/i915/gvt: no need to check return value of debugfs_create functionsGreg Kroah-Hartman
When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Because there is no need to check these functions, a number of local functions can be made to return void to simplify things as nothing can fail.

2019-08-13drm/i915/guc: keep breadcrumb irq always enabledDaniele Ceraolo Spurio
We rely on the tasklet to update the GT PM refcount, so we can't disable it even if we've processed all the requests for the engine because we might have detected the request completion before the interrupt arrived. Since on all platforms on which we plan to support guc submission we don't allow disabling the breadcrumb interrupts, we can further siplify the park/unpark flow by removing the interrupt pin/unpin. A BUG_ON has been added to catch changes to this flow that would require us to restore some kind of pinning. v2: split removal of engine_pin/unpin_breadcrumbs_irq to its own patch (chris) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20190812233152.2172-1-daniele.ceraolospurio@intel.com

2019-08-12drm/i915: Forgo last_fence active request trackingChris Wilson
We were using the last_fence to track the last request that used this vma that might be interpreted by a fence register and forced ourselves to wait for this request before modifying any fence register that overlapped our vma. Due to requirement that we need to track any XY_BLT command, linear or tiled, this in effect meant that we have to track the vma for its active lifespan anyway, so we can forgo the explicit last_fence tracking and just use the whole vma->active. Another solution would be to pipeline the register updates, and would help resolve some long running stalls for gen3 (but only gen 2 and 3!)
