Pull char/misc driver updates from Greg KH: "Here is the big char/misc driver patch pull request for 5.1-rc1. The largest thing by far is the new habanalabs driver for their AI accelerator chip.

Other than that, just the usual set of individual driver updates and fixes. There's an "odd" merge in here from the DRM tree that they asked me to do as the MEI driver is starting to interact with the i915 driver, and it needed some coordination.

2019-02-07drm: remove drmP.h from drm_modeset_helper.hSam Ravnborg1-1/+5
With the removal of drmP.h from drm_modeset_helper.h the drmP.h are no longer included by any include files in include/drm. The drmP.h file is thus only included explicit either in .c files or in local .h files. This makes the process of deleting the drmP.h includes easier as we have a more local dependency chain. v2: - moved updates of .c files in drm/ to a dedicated patch. This allows the updates to the *.c files to be committed without the removal part.

2019-02-06drm: disable uncached DMA optimization for ARM and arm64Ard Biesheuvel1-0/+18
The DRM driver stack is designed to work with cache coherent devices only, but permits an optimization to be enabled in some cases, where for some buffers, both the CPU and the GPU use uncached mappings, removing the need for DMA snooping and allocation in the CPU caches. The use of uncached GPU mappings relies on the correct implementation of the PCIe NoSnoop TLP attribute by the platform, otherwise the GPU will use cached mappings nonetheless. On x86 platforms, this does not seem to matter, as uncached CPU mappings will snoop the caches in any case. However, on ARM and arm64, enabling this optimization on a platform where NoSnoop is ignored results in loss of coherency, which breaks correct operation of the device. Since we have no way of detecting whether NoSnoop works or not, just disable this optimization entirely for ARM and arm64.

2019-02-05drm/atomic: Add drm_atomic_state->duplicatedLyude Paul1-0/+9
Since commit 39b50c603878 ("drm/atomic_helper: Stop modesets on unregistered connectors harder") We've been failing atomic checks if they try to enable new displays on unregistered connectors. This is fine except for the one situation that breaks atomic assumptions: suspend/resume. If a connector is unregistered before we attempt to restore the atomic state, something we end up failing the atomic check that happens when trying to restore the state during resume. Normally this would be OK: we try our best to make sure that the atomic state pre-suspend can be restored post-suspend, but failures at that point usually don't cause problems. That is of course, until we introduced the new atomic MST VCPI helpers: [drm:drm_atomic_helper_check_modeset [drm_kms_helper]] [CRTC:65:pipe B] active changed [drm:drm_atomic_helper_check_modeset [drm_kms_helper]] Updating routing for [CONNECTOR:123:DP-5] [drm:drm_atomic_helper_check_modeset [drm_kms_helper]] Disabling [CONNECTOR:123:DP-5] [drm:drm_atomic_get_private_obj_state [drm]] Added new private object 0000000025844636 state 000000009fd2899a to 000000003a13d7b8 WARNING: CPU: 6 PID: 1070 at drivers/gpu/drm/drm_dp_mst_topology.c:3153 drm_dp_atomic_release_vcpi_slots+0xb9/0x200 [drm_kms_helper] Modules linked in: fuse vfat fat snd_hda_codec_hdmi snd_hda_codec_realtek snd_hda_codec_generic joydev iTCO_wdt i915(O) wmi_bmof intel_rapl btusb btrtl x86_pkg_temp_thermal btbcm btintel coretemp i2c_algo_bit drm_kms_helper(O) crc32_pclmul snd_hda_intel syscopyarea sysfillrect snd_hda_codec sysimgblt snd_hda_core bluetooth fb_sys_fops snd_pcm pcspkr drm(O) psmouse snd_timer mei_me ecdh_generic i2c_i801 mei i2c_core ucsi_acpi typec_ucsi typec wmi thinkpad_acpi ledtrig_audio snd soundcore tpm_tis rfkill tpm_tis_core video tpm acpi_pad pcc_cpufreq uas usb_storage crc32c_intel nvme serio_raw xhci_pci nvme_core xhci_hcd CPU: 6 PID: 1070 Comm: gnome-shell Tainted: G W O 5.0.0-rc2Lyude-Test+ #1 Hardware name: LENOVO 20L8S2N800/20L8S2N800, BIOS N22ET35W (1.12 ) 04/09/2018 RIP: 0010:drm_dp_atomic_release_vcpi_slots+0xb9/0x200 [drm_kms_helper] Code: 00 4c 39 6d f0 74 49 48 8d 7b 10 48 89 f9 48 c1 e9 03 42 80 3c 21 00 0f 85 d2 00 00 00 48 8b 6b 10 48 8d 5d f0 49 39 ee 75 c5 <0f> 0b 48 c7 c7 c0 78 b3 a0 48 89 c2 4c 89 ee e8 03 6c aa ff b8 ea RSP: 0018:ffff88841235f268 EFLAGS: 00010246 RAX: ffff88841bf12ab0 RBX: ffff88841bf12aa8 RCX: 1ffff110837e2557 RDX: dffffc0000000000 RSI: 0000000000000000 RDI: ffffed108246bde0 RBP: ffff88841bf12ab8 R08: ffffed1083db3c93 R09: ffffed1083db3c92 R10: ffffed1083db3c92 R11: ffff88841ed9e497 R12: ffff888419555d80 R13: ffff8883bc499100 R14: ffff88841bf12ab8 R15: 0000000000000000 FS: 00007f16fbd4cd00(0000) GS:ffff88841ed80000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f1687c9f000 CR3: 00000003ba3cc003 CR4: 00000000003606e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: drm_atomic_helper_check_modeset+0xf21/0x2f50 [drm_kms_helper] ?

So, fix this by introducing the suspending option to drm_atomic_helper_duplicate_state() and use that to indicate in the atomic state that it's being used for suspending or resuming the system, and thus needs to be fixed up by the driver. We can then use the new state->duplicated hook to tell update_connector_routing() in drm_atomic_check_modeset() to allow for modesets on unregistered connectors, which allows us to restore atomic states that contain MST topologies that were removed after the state was duplicated and thus: mostly fixing suspend and resume.

This is only used by drm_irq_install(), which is an optional helper. For legacy pci devices this is required (due to interrupt sharing without msi/msi-x), and just making this the default exactly matches the behaviour of all existing drivers using the drm_irq_install() helpers.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter2-16/+27
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

2019-01-23drm: Add color management LUT validation helper (v4)Matt Roper1-0/+29
Some hardware may place additional restrictions on the gamma/degamma curves described by our LUT properties. E.g., that a gamma curve never decreases or that the red/green/blue channels of a LUT's entries must be equal. Let's add a helper function that drivers can use to test that a userspace-provided LUT is valid and doesn't violate hardware requirements. v2: - Combine into a single helper that just takes a bitmask of the tests to apply. (Brian Starkey) - Add additional check (always performed) that LUT property blob size is always a multiple of the LUT entry size. (stolen from ARM driver) v3: - Drop the LUT size check again since drm_atomic_replace_property_blob_from_id() already covers this for us. (Alexandru Gheorghe) v4: - Use an enum to describe possible test values rather than #define's; this is cleaner to provide kerneldoc for.

2019-01-18drm/fourcc: Add format info helpers for checking YUV sub-samplingPaul Kocialkowski1-0/+75
Display engine drivers often need to distinguish between different types of YUV sub-sampling. This introduces helpers to check for common sub-sampling ratios in their commonly-used denomination from the DRM format info.

2019-01-18drm/fourcc: Add format info helpers for checking YUV planes dispositionPaul Kocialkowski1-0/+42
It is often useful to check whether the DRM format info retrieved from the DRM framebuffer matches a specific YUV planes disposition. This introduces helpers to quickly check that a provided format info matches a YUV format with a specific disposition, in commonly-used terminology. The intent of providing helpers taking the format info instead of the fourcc alone is to avoid the overhead of iterating through all formats when the whole format info structure is available. As a result, these helpers are very simple so they are made inline.
