GVT implements a homogeneous vGPU as host GPU so max vGPU display pipes can't exceed HW. The inconsistency definition has potential risks which could cause array indexing overflow. Remove the unnecessary define of INTEL_GVT_MAX_PIPE and align with i915. Reviewed-by:

This trys to make 'kvmgt' module as self loadable instead of loading by i915/gvt device model. So hypervisor specific module could be stand-alone, e.g only after loading hypervisor specific module, GVT feature could be enabled via specific hypervisor interface, e.g VFIO/mdev. So this trys to use hypervisor module register/unregister interface for that. Hypervisor module needs to take care of module reference itself when working for hypervisor interface, e.g for VFIO/mdev, hypervisor module would reference counting mdev when open and release. This makes 'kvmgt' module really split from GVT device model. User needs to load 'kvmgt' to enable VFIO/mdev interface. v6: - remove unused variable v5: - put module reference in register error path v4: - fix checkpatch warning v3: - Fix module reference handling for device open and release. Unused mdev devices would be cleaned up in device unregister when module unload. v2: - Fix kvmgt order after i915 for built-in case Cc: "Yuan, Hang" <hang.yuan@intel.com> Cc: Alex Williamson <alex.williamson@redhat.com> Cc: "He, Min" <min.he@intel.com> Reviewed-by:

Currently we allocate a scratch page for each engine, but since we only ever write into it for post-sync operations, it is not exposed to userspace nor do we care for coherency. As we then do not care about its contents, we can use one page for all, reducing our allocations and avoid complications by not assuming per-engine isolation. For later use, it simplifies engine initialisation (by removing the allocation that required struct_mutex!) and means that we can always rely on there being a scratch page. v2: Check that we allocated a large enough scratch for I830 w/a Fixes: 06e562e7f515 ("drm/i915/ringbuffer: Delay after EMIT_INVALIDATE for gen4/gen5") # v4.18.20 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=108850Signed-off-by:

Convert the per context workaround handling code to run against the newly introduced common workaround framework and fuse the two to use the existing smarter list add helper, the one which does the sorted insert and merges registers where possible.

Existing macros are kept untouched for smaller code churn. v2: * Rename to list name ctx_wa_list and move from dev_priv to engine. v3: * API rename and parameters tweaking.

We stopped re-applying the GT workarounds after engine reset since commit 59b449d5 ("drm/i915: Split out functions for different kinds of workarounds"). Issue with this is that some of the GT workarounds live in the MMIO space which gets lost during engine resets. So far the registers in 0x2xxx and 0xbxxx address range have been identified to be affected. This losing of applied workarounds has obvious negative effects and can even lead to hard system hangs (see the linked Bugzilla). Rather than just restoring this re-application, because we have also observed that it is not safe to just re-write all GT workarounds after engine resets (GPU might be live and weird hardware states can happen), we introduce a new class of per-engine workarounds and move only the affected GT workarounds over. Using the framework introduced in the previous patch, we therefore after engine reset, re-apply only the workarounds living in the affected MMIO address ranges. v2: * Move Wa_1406609255:icl to engine workarounds as well. * Rename API. (Chris Wilson) * Drop redundant IS_KABYLAKE. (Chris Wilson) * Re-order engine wa/ init so latest platforms are first. (Rodrigo Vivi) Signed-off-by:

To enable later verification of GT workaround state at various stages of driver lifetime, we record the list of applicable ones per platforms to a list, from which they are also applied. The added data structure is a simple array of register, mask and value items, which is allocated on demand as workarounds are added to the list. This is a temporary implementation which later in the series gets fused with the existing per context workaround list handling. It is separated at this stage since the following patch fixes a bug which needs to be as easy to backport as possible. Also, since in the following patch we will be adding a new class of workarounds (per engine) which can be applied from interrupt context, we straight away make the provision for safe read-modify-write cycle. v2: * Change dev_priv to i915 along the init path. (Chris Wilson) * API rename. (Chris Wilson) v3: * Remove explicit list size tracking in favour of growing the allocation in power of two chunks. (Chris Wilson) v4: Chris Wilson: * Change wa_list_finish to early return. * Copy workarounds using the compiler for static checking. * Do not bother zeroing unused entries. * Re-order struct i915_wa_list. v5: * kmalloc_array. * Whitespace cleanup.

We inspect the requests under the assumption that they will be marked as completed when they are removed from the queue. Currently however, in the process of wedging the requests will be removed from the queue before they are completed, so rearrange the code to complete the fences before the locks are dropped. <1>[ 354.473346] BUG: unable to handle kernel NULL pointer dereference at 0000000000000250 <6>[ 354.473363] PGD 0 P4D 0 <4>[ 354.473370] Oops: 0000 [#1] PREEMPT SMP PTI <4>[ 354.473380] CPU: 0 PID: 4470 Comm: gem_eio Tainted: G U 4.20.0-rc4-CI-CI_DRM_5216+ #1 <4>[ 354.473393] Hardware name: Intel Corporation NUC7CJYH/NUC7JYB, BIOS JYGLKCPX.86A.0027.2018.0125.1347 01/25/2018 <4>[ 354.473480] RIP: 0010:__i915_schedule+0x311/0x5e0 [i915] <4>[ 354.473490] Code: 49 89 44 24 20 4d 89 4c 24 28 4d 89 29 44 39 b3 a0 04 00 00 7d 3a 41 8b 44 24 78 85 c0 74 13 48 8b 93 78 04 00 00 48 83 e2 fc <39> 82 50 02 00 00 79 1e 44 89 b3 a0 04 00 00 48 8d bb d0 03 00 00 <4>[ 354.473515] RSP: 0018:ffffc900001bba90 EFLAGS: 00010046 <4>[ 354.473524] RAX: 0000000000000003 RBX: ffff8882624c8008 RCX: f34a737800000000 <4>[ 354.473535] RDX: 0000000000000000 RSI: 0000000000000000 RDI: ffff8882624c8048 <4>[ 354.473545] RBP: ffffc900001bbab0 R08: 000000005963f1f1 R09: 0000000000000000 <4>[ 354.473556] R10: ffffc900001bba10 R11: ffff8882624c8060 R12: ffff88824fdd7b98 <4>[ 354.473567] R13: ffff88824fdd7bb8 R14: 0000000000000001 R15: ffff88824fdd7750 <4>[ 354.473578] FS: 00007f44b4b5b980(0000) GS:ffff888277e00000(0000) knlGS:0000000000000000 <4>[ 354.473590] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 <4>[ 354.473599] CR2: 0000000000000250 CR3: 000000026976e000 CR4: 0000000000340ef0 <4>[ 354.473611] Call Trace: <4>[ 354.473622] ? lock_acquire+0xa6/0x1c0 <4>[ 354.473677] ? i915_schedule_bump_priority+0x57/0xd0 [i915] <4>[ 354.473736] i915_schedule_bump_priority+0x72/0xd0 [i915] <4>[ 354.473792] i915_request_wait+0x4db/0x840 [i915] <4>[ 354.473804] ? get_pwq.isra.4+0x2c/0x50 <4>[ 354.473813] ? ___preempt_schedule+0x16/0x18 <4>[ 354.473824] ? wake_up_q+0x70/0x70 <4>[ 354.473831] ? wake_up_q+0x70/0x70 <4>[ 354.473882] ? gen6_rps_boost+0x118/0x120 [i915] <4>[ 354.473936] i915_gem_object_wait_fence+0x8a/0x110 [i915] <4>[ 354.473991] i915_gem_object_wait+0x113/0x500 [i915] <4>[ 354.474047] i915_gem_wait_ioctl+0x11c/0x2f0 [i915] <4>[ 354.474101] ? i915_gem_unset_wedged+0x210/0x210 [i915] <4>[ 354.474113] drm_ioctl_kernel+0x81/0xf0 <4>[ 354.474123] drm_ioctl+0x2de/0x390 <4>[ 354.474175] ? i915_gem_unset_wedged+0x210/0x210 [i915] <4>[ 354.474187] ? finish_task_switch+0x95/0x260 <4>[ 354.474197] ? lock_acquire+0xa6/0x1c0 <4>[ 354.474207] do_vfs_ioctl+0xa0/0x6e0 <4>[ 354.474217] ? __fget+0xfc/0x1e0 <4>[ 354.474225] ksys_ioctl+0x35/0x60 <4>[ 354.474233] __x64_sys_ioctl+0x11/0x20 <4>[ 354.474241] do_syscall_64+0x55/0x190 <4>[ 354.474251] entry_SYSCALL_64_after_hwframe+0x49/0xbe <4>[ 354.474260] RIP: 0033:0x7f44b3de65d7 <4>[ 354.474267] Code: b3 66 90 48 8b 05 b1 48 2d 00 64 c7 00 26 00 00 00 48 c7 c0 ff ff ff ff c3 66 2e 0f 1f 84 00 00 00 00 00 b8 10 00 00 00 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 8b 0d 81 48 2d 00 f7 d8 64 89 01 48 <4>[ 354.474293] RSP: 002b:00007fff974948e8 EFLAGS: 00000246 ORIG_RAX: 0000000000000010 <4>[ 354.474305] RAX: ffffffffffffffda RBX: 0000000000000000 RCX: 00007f44b3de65d7 <4>[ 354.474316] RDX: 00007fff97494940 RSI: 00000000c010646c RDI: 0000000000000007 <4>[ 354.474327] RBP: 00007fff97494940 R08: 0000000000000000 R09: 00007f44b40bbc40 <4>[ 354.474337] R10: 0000000000000000 R11: 0000000000000246 R12: 00000000c010646c <4>[ 354.474348] R13: 0000000000000007 R14: 0000000000000000 R15: 0000000000000000 v2: Avoid floating requests. v3: Can't call dma_fence_signal() under the timeline lock! v4: Can't call dma_fence_signal() from inside another fence either.
