commit ccc10574 upstream. During watermarks calculations, this value is used in 3 different places. Only one of them was not using a hardcoded 4. Move the code up so everybody can benefit from the actual value. This should only help on situations with Y tiling + 90/270 rotation + 1 or 2 bpp or NV12. Reviewed-by:

commit 4e4d3814 upstream. Bspec says: "The mailbox response data may not account for memory read latency. If the mailbox response data for level 0 is 0us, add 2 microseconds to the result for each valid level." This means we should only do the +2 in case wm[0] == 0, not always. So split the sanitizing implementation from the WA implementation and fix the WA implementation. v2: Add Fixes tag (Maarten).

commit be5c571b upstream. We were previously adding all the planes owned by the CRTC even when the ddb partitioning didn't change for them. As a consequence, a lot of functions were being called when we were just moving the cursor around the screen, such as skylake_update_primary_plane(). This was causing flickering on the primary plane when moving the cursor. I'm not 100% sure which operation caused the flickering, but we were writing to a lot of registers, so it could be any of these writes. With this patch, just moving the mouse won't add the primary plane to the commit since it won't trigger a change in DDB partitioning. v2: Use skl_ddb_entry_equal() (Lyude). v3: Change Reported-and-bisected-by: to Reported-by: for checkpatch Fixes: 05a76d3d ("drm/i915/skl: Ensure pipes with changed wms get added to the state") Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97888 Cc: Mike Lothian <mike@fireburn.co.uk> Reported-by:

commit ccebc23b upstream. i915 sometimes needs to disable planes in the middle of an atomic commit, and then reenable them later in the same commit. Because of this, we can't make the assumption that the state of the plane actually changed. Since the state of the plane hasn't actually changed, neither have it's watermarks. And if the watermarks hasn't changed then we haven't populated skl_results with anything, which means we'll end up zeroing out a plane's watermarks in the middle of the atomic commit without restoring them later. Simple reproduction recipe: - Get a SKL laptop, launch any kind of X session - Get two extra monitors - Keep hotplugging both displays (so that the display configuration jumps from 1 active pipe to 3 active pipes and back) - Eventually underrun Changes since v1: - Fix incorrect use of "it's" Changes since v2: - Add reproduction recipe Signed-off-by:

commit 27082493 upstream. Now that we can hook into update_crtcs and control the order in which we update CRTCs at each modeset, we can finish the final step of fixing Skylake's watermark handling by performing DDB updates at the same time as plane updates and watermark updates. The first major change in this patch is skl_update_crtcs(), which handles ensuring that we order each CRTC update in our atomic commits properly so that they honor the DDB flush order. The second major change in this patch is the order in which we flush the pipes. While the previous order may have worked, it can't be used in this approach since it no longer will do the right thing. For example, using the old ddb flush order: We have pipes A, B, and C enabled, and we're disabling C. Initial ddb allocation looks like this: | A | B |xxxxxxx| Since we're performing the ddb updates after performing any CRTC disablements in intel_atomic_commit_tail(), the space to the right of pipe B is unallocated. 1. Flush pipes with new allocation contained into old space. None apply, so we skip this 2. Flush pipes having their allocation reduced, but overlapping with a previous allocation. None apply, so we also skip this 3. Flush pipes that got more space allocated. This applies to A and B, giving us the following update order: A, B This is wrong, since updating pipe A first will cause it to overlap with B and potentially burst into flames. Our new order (see the code comments for details) would update the pipes in the proper order: B, A. As well, we calculate the order for each DDB update during the check phase, and reference it later in the commit phase when we hit skl_update_crtcs(). This long overdue patch fixes the rest of the underruns on Skylake. Changes since v1: - Add skl_ddb_entry_write() for cursor into skl_write_cursor_wm() Changes since v2: - Use the method for updating CRTCs that Ville suggested - In skl_update_wm(), only copy the watermarks for the crtc that was passed to us Changes since v3: - Small comment fix in skl_ddb_allocation_overlaps() Changes since v4: - Remove the second loop in intel_update_crtcs() and use Ville's suggestion for updating the ddb allocations in the right order - Get rid of the second loop and just use the ddb state as it updates to determine what order to update everything in (thanks for the suggestion Ville) - Simplify skl_ddb_allocation_overlaps() - Split actual overlap checking into it's own helper Fixes: 0e8fb7ba ("drm/i915/skl: Flush the WM configuration") Fixes: 8211bd5b ("drm/i915/skl: Program the DDB allocation") [omitting CC for stable, since this patch will need to be changed for such backports first] Testcase: kms_cursor_legacy Testcase: plane-all-modeset-transition Signed-off-by:

commit 896e5bb0 upstream. Since we have to write ddb allocations at the same time as we do other plane updates, we're going to need to be able to control the order in which we execute modesets on each pipe. The easiest way to do this is to just factor this section of intel_atomic_commit_tail() (intel_atomic_commit() for stable branches) into it's own function, and add an appropriate display function hook for it. Based off of Matt Rope's suggestions Changes since v1: - Drop pipe_config->base.active check in intel_update_crtcs() since we check that before calling the function Signed-off-by:

commit 62e0fb88 upstream. Thanks to Ville for suggesting this as a potential solution to pipe underruns on Skylake. On Skylake all of the registers for configuring planes, including the registers for configuring their watermarks, are double buffered. New values written to them won't take effect until said registers are "armed", which is done by writing to the PLANE_SURF (or in the case of cursor planes, the CURBASE register) register. With this in mind, up until now we've been updating watermarks on skl like this: non-modeset { - calculate (during atomic check phase) - finish_atomic_commit: - intel_pre_plane_update: - intel_update_watermarks() - {vblank happens; new watermarks + old plane values => underrun } - drm_atomic_helper_commit_planes_on_crtc: - start vblank evasion - write new plane registers - end vblank evasion } or modeset { - calculate (during atomic check phase) - finish_atomic_commit: - crtc_enable: - intel_update_watermarks() - {vblank happens; new watermarks + old plane values => underrun } - drm_atomic_helper_commit_planes_on_crtc: - start vblank evasion - write new plane registers - end vblank evasion } Now we update watermarks atomically like this: non-modeset { - calculate (during atomic check phase) - finish_atomic_commit: - intel_pre_plane_update: - intel_update_watermarks() (wm values aren't written yet) - drm_atomic_helper_commit_planes_on_crtc: - start vblank evasion - write new plane registers - write new wm values - end vblank evasion } modeset { - calculate (during atomic check phase) - finish_atomic_commit: - crtc_enable: - intel_update_watermarks() (actual wm values aren't written yet) - drm_atomic_helper_commit_planes_on_crtc: - start vblank evasion - write new plane registers - write new wm values - end vblank evasion } So this patch moves all of the watermark writes into the right place; inside of the vblank evasion where we update all of the registers for each plane. While this patch doesn't fix everything, it does allow us to update the watermark values in the way the hardware expects us to. Changes since original patch series: - Remove mutex_lock/mutex_unlock since they don't do anything and we're not touching global state - Move skl_write_cursor_wm/skl_write_plane_wm functions into intel_pm.c, make externally visible - Add skl_write_plane_wm calls to skl_update_plane - Fix conditional for for loop in skl_write_plane_wm (level < max_level should be level <= max_level) - Make diagram in commit more accurate to what's actually happening - Add Fixes: Changes since v1: - Use IS_GEN9() instead of IS_SKYLAKE() since these fixes apply to more then just Skylake - Update description to make it clear this patch doesn't fix everything - Check if pipes were actually changed before writing watermarks Changes since v2: - Write PIPE_WM_LINETIME during vblank evasion Changes since v3: - Rebase against new SAGV patch changes Changes since v4: - Add a parameter to choose what skl_wm_values struct to use when writing new plane watermarks Changes since v5: - Remove cursor ddb entry write in skl_write_cursor_wm(), defer until patch 6 - Write WM_LINETIME in intel_begin_crtc_commit() Changes since v6: - Remove redundant dirty_pipes check in skl_write_plane_wm (we check this in all places where we call this function, and it was supposed to have been removed earlier anyway) - In i9xx_update_cursor(), use dev_priv->info.gen >= 9 instead of IS_GEN9(dev_priv). We do this everywhere else and I'd imagine this needs to be done for gen10 as well Changes since v7: - Fix rebase fail (unused variable obj) - Make struct skl_wm_values *wm const - Fix indenting - Use INTEL_GEN() instead of dev_priv->info.gen Changes since v8: - Don't forget calls to skl_write_plane_wm() when disabling planes - Use INTEL_GEN(), not INTEL_INFO()->gen in intel_begin_crtc_commit() Fixes: 2d41c0b5 ("drm/i915/skl: SKL Watermark Computation") Signed-off-by:

commit 926317de upstream. This patch addresses a bug where a local EXTENDED_COPY WRITE or READ backend I/O request would always return SAM_STAT_CHECK_CONDITION, even if underlying xcopy_pt_cmd->se_cmd generated a different SCSI status code. ESX host environments expect to hit SAM_STAT_RESERVATION_CONFLICT for certain scenarios, and SAM_STAT_CHECK_CONDITION results in non-retriable status for these cases.

commit 449a1378 upstream. This patch addresses a bug where EXTENDED_COPY across multiple LUNs results in a CHECK_CONDITION when the source + destination are not located on the same physical node. ESX Host environments expect sense COPY_ABORTED w/ COPY TARGET DEVICE NOT REACHABLE to be returned when this occurs, in order to signal fallback to local copy method. As described in section 6.3.3 of spc4r22: "If it is not possible to complete processing of a segment because the copy manager is unable to establish communications with a copy target device, because the copy target device does not respond to INQUIRY, or because the data returned in response to INQUIRY indicates an unsupported logical unit, then the EXTENDED COPY command shall be terminated with CHECK CONDITION status, with the sense key set to COPY ABORTED, and the additional sense code set to COPY TARGET DEVICE NOT REACHABLE."

commit 527268df upstream. This patch fixes a regression in >= v4.1.y code where the original SCF_ACK_KREF assignment in target_get_sess_cmd() was dropped upstream in commit 054922bb, but the series for addressing TMR ABORT_TASK + LUN_RESET with fabric session reinstatement in commit febe562c still depends on this code in transport_cmd_finish_abort(). The regression manifests itself as a se_cmd->cmd_kref +1 leak, where ABORT_TASK + LUN_RESET can hang indefinately for a specific I_T session for drivers using SCF_ACK_KREF, resulting in hung kthreads.

commit fb445437 upstream. The XTS tweak (or IV) was initialized differently on little endian and big endian systems. Because the ciphertext depends on the XTS tweak, it was not possible to use an encrypted filesystem created by a little endian system on a big endian system and vice versa, even if they shared the same PAGE_SIZE. Fix this by always using little endian. This will break hypothetical big endian users of ext4 or f2fs encryption. However, all users we are aware of are little endian, and it's believed that "real" big endian users are unlikely to exist yet. So this might as well be fixed now before it's too late. Signed-off-by:

commit a5efb6b6 upstream. Usually a validity intercept is a programming error of the host because of invalid entries in the state description. We can get a validity intercept if the mode of the runtime instrumentation control block is wrong. As the host does not know which modes are valid, this can be used by userspace to trigger a WARN. Instead of printing a WARN let's return an error to userspace as this can only happen if userspace provides a malformed initial value (e.g. on migration). The kernel should never warn on bogus input. Instead let's log it into the s390 debug feature. While at it, let's return -EINVAL for all validity intercepts as this will trigger an error in QEMU like error: kvm run failed Invalid argument PSW=mask 0404c00180000000 addr 000000000063c226 cc 00 R00=000000000000004f R01=0000000000000004 R02=0000000000760005 R03=000000007fe0a000 R04=000000000064ba2a R05=000000049db73dd0 R06=000000000082c4b0 R07=0000000000000041 R08=0000000000000002 R09=000003e0804042a8 R10=0000000496152c42 R11=000000007fe0afb0 [...] This will avoid an endless loop of validity intercepts.
