Hi Geert, Ulrich Cc: Magnus > I have pushed renesas-drivers-2016-04-26-v4.6-rc5 to > https://git.kernel.org/cgit/linux/kernel/git/geert/renesas-drivers.git > > This tree is meant to ease development of platform support and drivers > for Renesas ARM SoCs. It is created by merging (a) the for-next branches > of various subsystem trees and (b) branches with driver code submitted > or planned for submission to maintainers into the development branch of > Simon Horman's renesas.git tree. For HDMI output point of view, as 1st step, it needs additional config. I attached it on this mail. I know Geert don't like it, but I hope Ulrich can handle it in formal version ;P My main problem is that HDMI1 output (= from CN17) is broken on this renesas-drivers version. It doesn't have such issue on previous version. renesas-drivers-2016-04-12-v4.6-rc3 : no problem renesas-drivers-2016-04-26-v4.6-rc5 : HDMI1 output broken This is log --- 8< -------------------------- [ 12.531390] [CRTC:48] vblank wait timed out [ 12.535647] ------------[ cut here ]------------ [ 12.541702] WARNING: CPU: 2 PID: 1274 at /opt/home/morimoto/WORK/linux/drivers/gpu/drm/drm_atomic_helper.c:1106 drm_atomic_helper_wait_for_vblanks+0x228/0x230 [ 12.558807] Modules linked in: [ 12.563323] [ 12.566252] CPU: 2 PID: 1274 Comm: irq/169-feb0000 Not tainted 4.6.0-rc5+ #218 [ 12.574942] Hardware name: Renesas Salvator-X board based on r8a7795 (DT) [ 12.583210] task: ffffffc038dcbc00 ti: ffffffc038814000 task.ti: ffffffc038814000 [ 12.592184] PC is at drm_atomic_helper_wait_for_vblanks+0x228/0x230 [ 12.599937] LR is at drm_atomic_helper_wait_for_vblanks+0x228/0x230 [ 12.607676] pc : [<ffffff80084593c8>] lr : [<ffffff80084593c8>] pstate: 60000145 [ 12.616562] sp : ffffffc038817a30 [ 12.621361] x29: ffffffc038817a30 x28: 0000000000000000 [ 12.628184] x27: ffffffc039188940 x26: 0000000000000098 [ 12.634988] x25: ffffffc038817ac0 x24: 0000000000000001 [ 12.641773] x23: 0000000000000130 x22: ffffffc039a9e800 [ 12.648552] x21: ffffffc038868400 x20: 0000000000000002 [ 12.655318] x19: ffffffc038880d80 x18: ffffff8088cf8d17 [ 12.662063] x17: 0000000000000007 x16: 0000000000000001 [ 12.668796] x15: 0000000000000006 x14: ffffff8008cf8d25 [ 12.675508] x13: ffffff8008cff150 x12: ffffffc039351470 [ 12.682202] x11: ffffff80088a9cc8 x10: 0000000000000001 [ 12.688879] x9 : 00000000ffffffff x8 : 0000000000000158 [ 12.695535] x7 : 0000000000000008 x6 : 0000000000000001 [ 12.702168] x5 : 0000000000000000 x4 : 0000000000000000 [ 12.708776] x3 : 0000000000000000 x2 : ffffffc03ef9c228 [ 12.715373] x1 : ffffffc038814000 x0 : 000000000000001f [ 12.721962] [ 12.724687] ---[ end trace d044c743a5b968f8 ]--- [ 12.730542] Call trace: [ 12.734212] Exception stack(0xffffffc038817870 to 0xffffffc038817990) [ 12.741857] 7860: ffffffc038880d80 0000000000000002 [ 12.750867] 7880: ffffffc038817a30 ffffff80084593c8 0000000000000002 ffffff8008cff150 [ 12.759873] 78a0: ffffffc0388178c0 ffffff8008a5b168 0000000100000001 ffffff8008cfcb98 [ 12.768856] 78c0: ffffffc038817960 ffffff80080f9e50 ffffff80080f9e18 ffffff8008a9a818 [ 12.777823] 78e0: ffffffc038868400 ffffffc039a9e800 0000000000000130 0000000000000001 [ 12.786768] 7900: ffffffc038817ac0 0000000000000098 000000000000001f ffffffc038814000 [ 12.795692] 7920: ffffffc03ef9c228 0000000000000000 0000000000000000 0000000000000000 [ 12.804587] 7940: 0000000000000001 0000000000000008 0000000000000158 00000000ffffffff [ 12.813451] 7960: 0000000000000001 ffffff80088a9cc8 ffffffc039351470 ffffff8008cff150 [ 12.822332] 7980: ffffff8008cf8d25 0000000000000006 [ 12.828274] [<ffffff80084593c8>] drm_atomic_helper_wait_for_vblanks+0x228/0x230 [ 12.836672] [<ffffff8008487158>] rcar_du_atomic_complete+0x50/0xb8 [ 12.843934] [<ffffff8008487438>] rcar_du_atomic_commit+0x278/0x288 [ 12.851181] [<ffffff800847fee0>] drm_atomic_commit+0x40/0x70 [ 12.857893] [<ffffff800845c0c0>] restore_fbdev_mode+0x270/0x2b0 [ 12.864850] [<ffffff800845e604>] drm_fb_helper_restore_fbdev_mode_unlocked+0x34/0x90 [ 12.873636] [<ffffff800845e68c>] drm_fb_helper_set_par+0x2c/0x60 [ 12.880680] [<ffffff800845e570>] drm_fb_helper_hotplug_event+0xd8/0x138 [ 12.888288] [<ffffff800845f500>] drm_fbdev_cma_hotplug_event+0x10/0x20 [ 12.895755] [<ffffff80084874dc>] rcar_du_output_poll_changed+0x14/0x20 [ 12.903229] [<ffffff80084521e8>] drm_kms_helper_hotplug_event+0x28/0x38 [ 12.910797] [<ffffff8008452b70>] drm_helper_hpd_irq_event+0x100/0x190 [ 12.918185] [<ffffff80084b9e48>] dw_hdmi_irq+0xd0/0x180 [ 12.924341] [<ffffff80080fc3f0>] irq_thread_fn+0x28/0x68 [ 12.930564] [<ffffff80080fc6e0>] irq_thread+0x128/0x1e8 [ 12.936683] [<ffffff80080d5d98>] kthread+0xd0/0xe8 [ 12.942379] [<ffffff8008084e10>] ret_from_fork+0x10/0x40 --- 8< --------------------------
