2016-02-01drm/exynos: dp: Fix panel and bridge lookup logicJavier Martinez Canillas1-30/+25
Commit a9fa852886fd ("drm/exynos: dp: add of_graph dt binding support for panel") made the Exynos DP DT binding more consistent since the OF graph could be used to lookup either a panel or a bridge device node. Before that commit, a panel would be looked up using a phandle and a bridge using the OF graph which made the DT binding not consistent. But the patch broke the later case since not finding a panel dev node would cause the driver's to do a probe deferral instead of attempting to lookup a bridge device node associated with the remote endpoint. So instead of returning a -EPROBE_DEFER if a panel is not found, check if there's a bridge and only do a probe deferral if both aren't found.

2016-02-01drm: exynos: make PM functions as __maybe_unusedArnd Bergmann1-4/+2
The newly added runtime-pm support for exynos-drm encloses the pm functions in an #ifdef, but not the functions that are called from them and nowhere else, which produces warnings: drm/exynos/exynos_drm_dsi.c:733:13: warning: 'exynos_dsi_disable_clock' defined but not used [-Wunused-function] static void exynos_dsi_disable_clock(struct exynos_dsi *dsi) ^ drm/exynos/exynos_drm_dsi.c:1291:13: warning: 'exynos_dsi_disable_irq' defined but not used [-Wunused-function] static void exynos_dsi_disable_irq(struct exynos_dsi *dsi) ^ This removes the #ifdef and instead marks the functions as __maybe_unused, so gcc can silently discard them and all called functions when CONFIG_PM is disabled.

Commit 5bab6f60cb4d ("drm/i915: Serialise updates to GGTT with access through GGTT on Braswell") depended upon a working stop_machine() and so forced the selection of STOP_MACHINE. However, commit 86fffe4a61dd ("kernel: remove stop_machine() Kconfig dependency") removed the option STOP_MACHINE from init/Kconfig and ensured that stop_machine() universally works. Due to the order in which the patches were applied, removing the select from DRM_I915 got lost during merging. Remove the now obsolete select statement.

2016-01-29drm/i915: Fix NULL plane->fb oops on SKLVille Syrjälä1-1/+1
In this atomic age, we can't trust the plane->fb pointer anymore. It might get update too late. Instead we are supposed to use the plane_state->fb pointer instead. Let's do that in intel_plane_obj_offset() and avoid problems from dereferencing the potentially stale plane->fb pointer. Paulo found this with 'kms_frontbuffer_tracking --show-hidden --run-subtest nop-1p-rte' but it can be reproduced with just plain old kms_setplane. I was too lazy to bisect this, so not sure exactly when it broke. The most obvious candidate commit ce7f17285639 ("drm/i915: Fix i915_ggtt_view_equal to handle rotation correctly") was actually still fine, so it must have broken some time after that. Here's the resulting fireworks: BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<ffffffffa02d2d9a>] intel_fill_fb_ggtt_view+0x1b/0x15a [i915] PGD 8a5f6067 PUD 8a5f5067 PMD 0 Oops: 0000 [#1] PREEMPT SMP Modules linked in: i915 i2c_algo_bit drm_kms_helper syscopyarea sysfillrect sysimgblt fb_sys_fops drm intel_gtt agpgart netconsole mousedev hid_generic psmouse usbhid atkbd libps2 coretemp hwmon efi_pstore intel_rapl iosf_mbi x86_pkg_temp_thermal efivars pcspkr e1000e sdhci_pci ptp pps_core sdhci i2c_i801 mmc_core i2c_hid hid i8042 serio evdev sch_fq_codel ip_tables x_tables ipv6 autofs4 CPU: 1 PID: 260 Comm: kms_plane Not tainted 4.4.0-skl+ #171 Hardware name: Intel Corporation Skylake Client platform/Skylake Y LPDDR3 RVP3, BIOS SKLSE2R1.R00.B104.B00.1511030553 11/03/2015 task: ffff88008bde2d80 ti: ffff88008a6ec000 task.ti: ffff88008a6ec000 RIP: 0010:[<ffffffffa02d2d9a>] [<ffffffffa02d2d9a>] intel_fill_fb_ggtt_view+0x1b/0x15a [i915] RSP: 0018:ffff88008a6efa10 EFLAGS: 00010086 RAX: 0000000000000001 RBX: ffff8801674f4240 RCX: 0000000000000014 RDX: ffff88008a7440c0 RSI: 0000000000000000 RDI: ffff88008a6efa40 RBP: ffff88008a6efa30 R08: ffff88008bde3598 R09: 0000000000000001 R10: ffff88008b782000 R11: 0000000000000000 R12: 0000000000000000 R13: ffff88008a7440c0 R14: 0000000000000000 R15: ffff88008a7449c0 FS: 00007fa0c07a28c0(0000) GS:ffff88016ec40000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 000000008a6ff000 CR4: 00000000003406e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Stack: ffff8801674f4240 0000000000000000 ffff88008a7440c0 0000000000000000 ffff88008a6efaa0 ffffffffa02daf25 ffffffff814ec80e 0000000000070298 ffff8800850d0000 ffff88008a6efaa0 ffffffffa02c49c2 0000000000000002 Call Trace: [<ffffffffa02daf25>] intel_plane_obj_offset+0x2d/0xa9 [i915] [<ffffffff814ec80e>] ? _raw_spin_unlock_irqrestore+0x4b/0x60 [<ffffffffa02c49c2>] ? gen9_write32+0x2e8/0x3b8 [i915] [<ffffffffa02eecfc>] skl_update_plane+0x203/0x4c5 [i915] [<ffffffffa02ca1ab>] intel_plane_atomic_update+0x53/0x6a [i915] [<ffffffffa02494a4>] drm_atomic_helper_commit_planes_on_crtc+0x142/0x1d5 [drm_kms_helper] [<ffffffffa02de44b>] intel_atomic_commit+0x1262/0x1350 [i915] [<ffffffffa024a0ee>] ? __drm_atomic_helper_crtc_duplicate_state+0x2f/0x41 [drm_kms_helper] [<ffffffffa01ef089>] ? drm_atomic_check_only+0x3e3/0x552 [drm] [<ffffffffa01ef245>] drm_atomic_commit+0x4d/0x52 [drm] [<ffffffffa024996b>] drm_atomic_helper_update_plane+0xcb/0x118 [drm_kms_helper] [<ffffffffa01e42e8>] __setplane_internal+0x1c8/0x224 [drm] [<ffffffffa01e477f>] drm_mode_setplane+0x14e/0x172 [drm] [<ffffffffa01d8117>] drm_ioctl+0x265/0x3ad [drm] [<ffffffffa01e4631>] ? drm_mode_cursor_common+0x158/0x158 [drm] [<ffffffff810d00ab>] ? current_kernel_time64+0x5e/0x98 [<ffffffff810a76ea>] ? trace_hardirqs_on_caller+0x17a/0x196 [<ffffffff8119880f>] do_vfs_ioctl+0x42b/0x4ea [<ffffffff811a2b72>] ? __fget_light+0x4d/0x71 [<ffffffff81198911>] SyS_ioctl+0x43/0x61 [<ffffffff814ed057>] entry_SYSCALL_64_fastpath+0x12/0x6f Cc: drm-intel-fixes@lists.freedesktop.org Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Testcase: igt/kms_plane Reported-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1453220597-28973-1-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> (cherry picked from commit e794129444aba459e9bedf5080bfb4605f933c32) Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2016-01-26drm/etnaviv: call correct function when trying to vmap a DMABUFLucas Stach3-11/+34
When trying to get the vmap address of an imported buffer, we must call into the appropriate helper function, to allow the exporter to establish the vmap, instead of trying to vmap the buffer on our own. Add an indirection through etnaviv_gem_ops to allow the correct implementation to be called. Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
2016-01-26drm/etnaviv: rename etnaviv_gem_vaddr to etnaviv_gem_vmapLucas Stach4-4/+4

2016-01-26drm/etnaviv: fix get pages error path in etnaviv_gem_vaddrLucas Stach2-3/+5
In case that etnaviv_gem_get_pages is unable to get the required pages the object mutex needs to be unlocked. Also return NULL in this case instead of propagating the error, as callers of this function might not be prepared to handle a pointer error, but expect this call to follow the semantics of a plain vmap to return NULL in case of an error.

Don't init fbdev if we don't have connectors. E.g., if you have a PX laptop with the displays attached to an IGP with no driver support, you may end up with a blank screen rather than falling back to vesa, etc. Based on a similar radeon patch from Rob Clark.

2016-01-26drm/radeon: only init fbdev if we have connectorsRob Clark1-2/+4
This fixes an issue that was noticed on an optimus/prime laptop with a kernel that was old enough to not support the integrated intel gfx (which was driving all the outputs), but did have support for the discrete radeon gpu. The end result was not falling back to VESA and leaving the user with a black screen. (Plus it is kind of silly to create an framebuffer device if there are no outputs hooked up to the gpu.)
