Commit a6f75aa1 ("drm/exynos: fimd: add HW trigger support") added hardware trigger support to the FIMD controller driver. But this broke the display in at least the Exynos5800 Peach Pi Chromebook. So until the issue is fixed, avoid using HW trigger for the Exynos5420 based boards and use SW trigger as it was before the mentioned commit. Signed-off-by:

The field value is only checked in fimd_setup_trigger() if .trg_type is I80_HW_TRG so there's no point in setting this field for the s3c6400 if is never going to be used since .trg_type is not set. Signed-off-by:

Commit 3424e3a4 ("drm: bridge: analogix/dp: split exynos dp driver to bridge directory") split the Exynos DP core driver into a core driver and a bridge driver for the Analogix chip since that is also used by Rockchip. But the change introduced a regression causing a NULL pointer dereference when trying to access an uninitialized connector in the driver .get_modes: Fix this by instead of having a connector struct for both the Exynos and Analogix drivers, just use the connector initialized in the bridge driver.

just a single fix for a regression introduced by IOMMU API changes in v4.7. * 'drm-etnaviv-fixes' of git://git.pengutronix.de/git/lst/linux: drm/etnaviv: initialize iommu domain page size
-
Lucas Stach authored
Since d16e0faa (iommu: Allow selecting page sizes per domain) the iommu core demands the page size to be set per domain, otherwise any mapping attempts will be dropped. Make sure to set a valid page size for the etnaviv iommu. Signed-off-by:

This reverts commit 1733a2ad. There is apparently something amiss with the way the TTM code handles DMA buffers, which the above commit was attempting to work around for arm64 systems with non-coherent PCI. Unfortunately, this completely breaks systems *with* coherent PCI (which appear to be the majority). Booting a plain arm64 defconfig + CONFIG_DRM + CONFIG_DRM_NOUVEAU on a machine with a PCI GPU having coherent dma_map_ops (in this case a 7600GT card plugged into an ARM Juno board) results in a fatal crash: [ 2.803438] nouveau 0000:06:00.0: DRM: allocated 1024x768 fb: 0x9000, bo ffffffc976141c00 [ 2.897662] Unable to handle kernel NULL pointer dereference at virtual address 000001ac [ 2.897666] pgd = ffffff8008e00000 [ 2.897675] [000001ac] *pgd=00000009ffffe003, *pud=00000009ffffe003, *pmd=0000000000000000 [ 2.897680] Internal error: Oops: 96000045 [#1] PREEMPT SMP [ 2.897685] Modules linked in: [ 2.897692] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.6.0-rc5+ #543 [ 2.897694] Hardware name: ARM Juno development board (r1) (DT) [ 2.897699] task: ffffffc9768a0000 ti: ffffffc9768a8000 task.ti: ffffffc9768a8000 [ 2.897711] PC is at __memcpy+0x7c/0x180 [ 2.897719] LR is at OUT_RINGp+0x34/0x70 [ 2.897724] pc : [<ffffff80083465fc>] lr : [<ffffff800854248c>] pstate: 80000045 [ 2.897726] sp : ffffffc9768ab360 [ 2.897732] x29: ffffffc9768ab360 x28: 0000000000000001 [ 2.897738] x27: ffffffc97624c000 x26: 0000000000000000 [ 2.897744] x25: 0000000000000080 x24: 0000000000006c00 [ 2.897749] x23: 0000000000000005 x22: ffffffc97624c010 [ 2.897755] x21: 0000000000000004 x20: 0000000000000004 [ 2.897761] x19: ffffffc9763da000 x18: ffffffc976b2491c [ 2.897766] x17: 0000000000000007 x16: 0000000000000006 [ 2.897771] x15: 0000000000000001 x14: 0000000000000001 [ 2.897777] x13: 0000000000e31b70 x12: ffffffc9768a0080 [ 2.897783] x11: 0000000000000000 x10: fffffffffffffb00 [ 2.897788] x9 : 0000000000000000 x8 : 0000000000000000 [ 2.897793] x7 : 0000000000000000 x6 : 00000000000001ac [ 2.897799] x5 : 00000000ffffffff x4 : 0000000000000000 [ 2.897804] x3 : 0000000000000010 x2 : 0000000000000010 [ 2.897810] x1 : ffffffc97624c010 x0 : 00000000000001ac ...

Since commit 0955c125 ("drm/crtc: take references to connectors used in a modeset. (v2)"), the reference counts of all connectors in the drm_mode_set given to drm_crtc_helper_set_config are incremented, and then the reference counts of all connectors are decremented on success, but in a temporary copy of the connector structure. This leads to the following error after the first modeset on imx-drm: Unable to handle kernel NULL pointer dereference at virtual address 00000004 pgd = ad8c4000 [00000004] *pgd=3d9c5831, *pte=00000000, *ppte=00000000 Internal error: Oops: 817 [#1] PREEMPT SMP ARM Modules linked in: CPU: 1 PID: 190 Comm: kmsfb-manage Not tainted 4.7.0-rc1+ #657 Hardware name: Freescale i.MX6 Quad/DualLit: [<80506098>] lr : [<80252e94>] psr: 200c0013 sp : adca7ca8 ip : adca7b90 fp : adca7cd4 r10: 00000000 r9 : 00000100 r8 : 00000200 r7 : af3c9800 r6 : aded7848 r5 : aded7800 r4 : 00000000 r3 : af3ca058 r2 : 00000200 r1 : af3ca058 r0 : 00000000 Flags: nzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none Control: 10c5387d Table: 3d8c404a DAC: 00000051 Process kmsfb-manage (pid: 190, stack limit = 0xadca6210) Stack: (0xadca7ca8 to 0xadca8000) 7ca0: 805190e0 aded7800 aded7820 80501a88 8155a290 af3c9c6c 7cc0: adca7ddc 0000000f adca7cec adca7cd8 80519104 80506044 805190e0 aded7800 7ce0: adca7d04 adca7cf0 80501ac0 805190ec aded7820 aded7814 adca7d24 adca7d08 7d00: 804fdb80 80501a94 aded7800 af3ca010 aded7afc af3c9c60 adca7d94 adca7d28 7d20: 804e3518 804fdb20 00000000 af3c9b1c adca7d50 81506f44 00000000 8093c500 7d40: af3c9c6c ae4f2ca8 ae4f2c18 00000000 00000000 ae637f00 00000000 aded7800 7d60: 00000001 af3c9800 af23c300 ae77fcc0 ae4f2c18 00000001 af3c9800 8155a290 7d80: af1af700 adca6000 adca7db4 adca7d98 804fea6c 804e2de4 adca7e50 adb3d940 7da0: 00000001 af3c9800 adca7e24 adca7db8 8050440c 804fea0c ae77fcc0 00000003 7dc0: adca7e24 adb3d940 af1af700 ae77fcc0 ae77fccc ae4f2c18 8083d44c ae77fcc0 7de0: ae4002 80d03040 adca7e64 adca7e40 adca7e50 80503f08 7e40: 7ebd5630 adca7e50 00000068 c06864a2 7ebd5be8 00000000 00000001 00000018 7e60: 00000026 00000000 00000000 00000000 00000001 000115bc 05010500 05a0059f 7e80: 03200000 03360321 00000337 0000003c 00000000 00000040 30383231 30303878 7ea0: 00000000 00000000 00000000 00000000 00000000 00000000 80173058 80172e30 7ec0: 80d77d32 00004000 adf7d900 00000003 00000000 7ebd5630 af342bb0 adfe3b80 7ee0: 80272f50 00000003 adca6000 00000000 adca7f7c adca7f00 802725ec 804f52cc 7f00: 802809cc 80178450 00000000 00000000 80280880 80145904 adb3d8c0 adf7d990 7f20: ffffffff 00000003 00004000 01614c10 c06864a2 00000003 adca6000 00000000 7f40: adca7f6c adca7f50 80280b04 8028088c 000115bc adfe3b81 7ebd5630 adfe3b80 7f60: c06864a2 00000003 adca6000 00000000 adca7fa4 adca7f80 80272f50 80272548 7f80: 000115bc 00017050 00000001 01614c10 00000036 801089e4 00000000 adca7fa8 7fa0: 80108840 80272f18 00017050 00000001 00000003 c06864a2 7ebd5630 000115bc 7fc0: 00017050 00000001 01614c10 00000036 00000003 00000000 00000026 00000018 7fe0: 00016f38 7ebd562c 0000b5e9 76ef31e6 400c0030 00000003 ff5f37db bfe7dd4d Backtrace: [<80506038>] (drm_connector_cleanup) from [<80519104>] (dw_hdmi_connector_destroy+0x24/0x28) r10:0000000f r9:adca7ddc r8:af3c9c6c r7:8155a290 r6:80501a88 r5:aded7820 r4:aded7800 r3:805190e0 [<805190e0>] (dw_hdmi_connector_destroy) from [<80501ac0>] (drm_connector_free+0x38/0x3c) r4:aded7800 nreference) from [<804e3518>] (drm_crtc_helper_set_config+0x740/0xbf4) r6:af3c9c60 r5:aded7afc r4:af3ca010 r3:aded7800 [<804e2dd8>] (drm_crtc_helper_set_config) from [<804fea6c>] (drm_mode_set_config_internal+0x6c/0xf4) r10:adca6000 r9:af1af700 r8:8155a290 r7:af3c9800 r6:00000001 r5:ae4f2c18 r4:ae77fcc0 [<804fea00>] (drm_mode_set_config_internal) from [<8050440c>] (drm_mode_setcrtc+0x504/0x57c) r7:af3c9800 r6:00000001 r5:adb3d940 r4:adca7e50 [<80503f08>] (drm_mode_setcrtc) from [<804f5404>] (drm_ioctl+0x144/0x4dc) r10:ada2e000 r9:000000a2 r8:af3c9800 r7:8155a290 r6:809320b4 r5:00000051 r4:adca7e50 [<804f52c0>] (drm_ioctl) from [<802725ec>] (do_vfs_ioctl+0xb0/0x9d0) r10:00000000 r9:adca6000 r8:00000003 r7:80272f50 r6:adfe3b80 r5:af342bb0 r4:7ebd5630 [<8027253c>] (do_vfs_ioctl) from [<80272f50>] (SyS_ioctl+0x44/0x6c) r10:00000000 r9:adca6000 r8:00000003 r7:c06864a2 r6:adfe3b80 r5:7ebd5630 r4:adfe3b81 [<80272f0c>] (SyS_ioctl) from [<80108840>] (ret_fast_syscall+0x0/0x1c) r8:801089e4 r7:00000036 r6:01614c10 r5:00000001 r4:00017050 r3:000115bc Code: 0a00000c e5932004 e1a01003 e1a0a004 (e5842004) ---[ end trace 9a7257572ccacb16 ]--- Only the reference count of connectors that weren't previously bound to an encoder should be incremented after a call to drm_crtc_helper_set_config. And only the reference count of connectors that were previously bound to an encoder and are unbound afterwards should ever be decremented. The reference counts of the temporary copies in the save_connectors should not be touched at all. This patch fixes the above error by only incrementing the reference count of those connectors in the set that are initially not bound to any encoder, and also by restoring the reference count of only those connectors in the set in the failure case. "Note that this can only be hit when fbdev emulation is disabled, since then the refcount drops from 1 to 0 and we call the connector destroy functions on the backup copy, which eventually results in tears. With fbdev emulation the refcount only goes down from 2 to 1 ever. And since we unconditionally increment the refcount on the real object, the refcount of that will slowly increase. The backup connector's refcount doesn't matter, since we kfree() that either way in the end of drm_crtc_helper_set_config()."

Thanks to Ville Syrjälä for pointing me towards the cause of this issue. Unfortunately one of the sideaffects of having the refclk for a DPLL set to SSC is that as long as it's set to SSC, the GPU will prevent us from powering down any of the pipes or transcoders using it. A couple of BIOSes enable SSC in both PCH_DREF_CONTROL and in the DPLL configurations. This causes issues on the first modeset, since we don't expect SSC to be left on and as a result, can't successfully power down the pipes or the transcoders using it. Here's an example from this Dell OptiPlex 990: [drm:intel_modeset_init] SSC enabled by BIOS, overriding VBT which says disabled [drm:intel_modeset_init] 2 display pipes available.

A better solution would be to add refcounts for the SSC source, but for now leaving the source clock on should suffice. Changes since v4: - Fix calculation of final for systems with LVDS panels (fixes BUG() on CI test suite) Changes since v3: - Move temp variable into loop - Move checks for using_ssc_source to after we've figured out has_ck505 - Add using_ssc_source to debug output Changes since v2: - Fix debug output for when we disable the CPU source Changes since v1: - Leave the SSC source clock on instead of just shutting it off on all of the DPLL configurations.

This reverts commit 2ba272d7. The issue fixed by this patch is specific to compute rings and the previous patch was enough. Additionally, this patch as been traced to strange behavior on some CZ systems so we might as well drop it.

When executing in a PCI passthrough based virtuzliation environment, the hypervisor will usually attempt to send a PCIe bus reset signal to the ASIC when the VM reboots. In this scenario, the card is not correctly initialized, but we still consider it to be posted. Therefore, in a passthrough based environemnt we should always post the card to guarantee it is in a good state for driver initialization.

The VBT has these mysterious H/V image sizes as part of the display timings. Looking at some dumps those appear to be the physical dimensions in mm. Which makes sense since the timing descriptor matches the format used by EDID detailed timing descriptor, which defines these as "H/V Addressable Video Image Size in mm". So let's use that information from the panel fixed mode to get the physical dimensions for LVDS/eDP/DSI displays. And with that we can fill out the display_info so that userspace can get at it via GetConnector. v2: Use (hi<<8)|lo instead of broken (hi<<4)+lo Handle LVDS and eDP too Cc: Stephen Just <stephenjust@gmail.com> Tested-by:Stephen Just <stephenjust@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=96255Signed-off-by:

Apparently some CHV boards failed to hook up the port presence straps for HDMI ports as well (earlier we assumed this problem only affected eDP ports). So let's check the VBT in addition to the strap, and if either one claims that the port is present go ahead and register the relevant connector. While at it, change port D to register DP before HDMI as we do for ports B and C since commit 457c52d8 ("drm/i915: Only ignore eDP ports that are connected") Also print a debug message when we register a HDMI connector to aid in diagnosing missing/incorrect ports. We already had such a print for DP/eDP. v2: Improve the comment in the code a bit, note the port D change in the commit message Cc: Radoslav Duda <radosd@radosd.com> Tested-by:

If the VBT says that a certain port should be eDP (and hence fused off from HDMI), but in reality it isn't, we need to try and acquire the HDMI connection instead. So only trust the VBT edp setting if we can connect to an eDP device on that port.
