RFC on upstreaming of a Mediatek DRM modesetting driver
by Frank Binns 02 Dec '14

02 Dec '14

Hi, We are currently in negotiations with one of our customers (Mediatek) on a strategy that will allow them to push a DRM modesetting driver into the upstream kernel. We are writing to get people's opinions and feedback on our proposed approach. Currently, our driver is structured in such a way that the display driver is more tightly integrated with the GPU driver than we would like. Although our kernel driver has been shipped with a GPL license for a long time, it is not in a form that would be considered acceptable upstream. Unfortunately, it is going to be a long process to get this part of the driver into a reasonable state. However, in the meantime, we don't want to prevent customer portions of the driver from being upstreamed. With the work done on recent kernels, and with a willing partner in Mediatek, we now think that we can restructure our driver in such a way as to allow this to happen. We see two basic approaches to achieving this: 1) Two independent DRM drivers, i.e. modesetting and render node drivers 2) A single componentised DRM driver Our (IMG's) preferred approach is to have a single componentised DRM driver. This is due to the following reasons: - Existing user space is not fully prepared to handle render nodes. - There is concern that any IMG DRM render node driver will need knowledge about multiple SoCs, each one being from a different vendor. Would this be deemed acceptable? - There is a trend, at least for DRM SoC drivers, towards using the component interface. Although there appears to be very few (one?) examples of GPU component drivers. To give some high level details on how we expect the componentised DRM driver model to work, each vendor (in this case Mediatek) will write their own DRM driver (supporting modesetting, dumb buffers, GEM, prime, etc) and IMG will provide an almost entirely independent component driver that adds in GPU support. Until our GPU driver is in a suitable state this will most likely necessitate a small kernel patch to wire up support, e.g. GPU specific ioctls. Cross-device and cross-process memory allocations will be made using the DRM driver. In order for this memory to be shared with the GPU component driver it will be necessary, at least for the time being, to export it via prime and import it via a GPU ioctl. Synchronisation between the display and GPU will be performed via reservation objects. Does this sound like a sane approach? Questions and/or feedback is very welcome. Thanks Frank

[PATCH] drm/i915 Trouble with minimum brightness
by Jay Aurabind 02 Dec '14

02 Dec '14

Hello all, I notice that some activity has been going on with the minimum value of display brightness recently (e1c412e7575). But the minimum value thats currently chosen is not at all acceptable for my eyes. My display is working perfectly without that restriction on minimum intensity. I tend to stare at the screen a lot and the current minimum settings is straining my eyes. Even if you say that it may not be good for the devices, I still insist, because I want my *display* to fail first, not my eyes. So please try providing a way for the needy users to override this minimum settings. I hope adding a module parameter would be easy fix. Something like this: ? (I dont call myself a kernel programmer yet, just scratching the surface) Provide provision for users to disable restriction on minimum brightness value introduced in: commit e1c412e75754ab7b7002f3e18a2652d999c40d4b Author: Jani Nikula <jani.nikula(a)intel.com> Date: Wed Nov 5 14:46:31 2014 +0200 drm/i915: safeguard against too high minimum brightness There are systems which work reliably without restriction on minimum value of display brightness. Also the arbitrary value may be too high for many users as well.

omapdrm/pvr kernel crash with camera capture and display application
by Vikas Patil 02 Dec '14

02 Dec '14

Hi, I am running camera capture application (based on omap iss, v4l2, videobuf2-dma-contig, x11, gles2) on customized OMAP5 board with 3.8 kernel and rootfs based on GLSDK 6.04.00.02. However within 12 to 30 minutes it crashes with following trace. I have reverted Link 1 patch from omap_gem.c and integrated link 2 patch to fix another crash I was observing Link1: http://git.omapzoom.org/?p=kernel/omap.git;a=commitdiff;h=f968e920452aa3061… Link2: http://omapzoom.org/?p=kernel/omap.git;a=commitdiff;h=0f88f7ca8283f9407a17f… Could anyone give some inputs/suggestion to understand and fix this crash? How should I start debugging it?

[Bug 86244] radeon kernel panic when booted with HDMI
by bugzilla-daemon＠freedesktop.org 02 Dec '14

02 Dec '14

https://bugs.freedesktop.org/show_bug.cgi?id=86244 Bug ID: 86244 Summary: radeon kernel panic when booted with HDMI Product: DRI Version: unspecified Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/Radeon Assignee: dri-devel(a)lists.freedesktop.org Reporter: tiwai(a)suse.de We've got a few bug reports about the kernel panic showing radeon kernel code path. All seem related with HDMI. Typically, the kernel panic or Oops is triggered when the system is booted with HDMI. One reporter mentioned that it happens when switching to HDMI-only mode even after hotplugging HDMI, too. The affected kernels are, at least, 3.16 and 3.17. One report mentions that it happens with 3.15, too. Oops looks like: BUG: unable to handle kernel paging request at 000000040101077c IP: [<ffffffffa00631dd>] drm_helper_connector_dpms+0x4d/0x230 [drm_kms_helper] PGD bb0db067 PUD 0 Oops: 0000 [#1] SMP CPU: 0 PID: 817 Comm: Xorg Not tainted 3.16.6-2-default #1 Hardware name: MEDION S561X/S561X, BIOS A16C1IM7 Ver1.0G 09/10/2009 task: ffff8800bab88290 ti: ffff8800babac000 task.ti: ffff8800babac000 RIP: 0010:[<ffffffffa00631dd>] [<ffffffffa00631dd>] drm_helper_connector_dpms+0x4d/0x230 [drm_kms_helper] RSP: 0018:ffff8800babafd50 EFLAGS: 00010286 RAX: ffffffffa0063190 RBX: ffff880037201e00 RCX: 000000040101046c RDX: 0000000000000003 RSI: 0000000000000003 RDI: ffff8800ba310400 RBP: 6144796669746f6e R08: 0000000000000008 R09: ffff88012fd68d40 R10: ffffffffa00332e0 R11: ffff8800babafe08 R12: 0000000000000003 R13: 0000000000000003 R14: 0000000000000000 R15: 00000000fffffff2 FS: 00007ff1601658c0(0000) GS:ffff88013fc00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000000040101077c CR3: 00000000b9b4d000 CR4: 00000000000407f0 Stack: ffff8800372af800 ffff8800babafdb0 ffff8800ba310428 ffff8800b9e26750 0000000000000003 ffffffffa0023fc6 ffff8800babafe08 00000000000000ab fffffffffffffff2 ffff8800372af800 ffff880138b05800 ffffffffa002400e Call Trace: [<ffffffffa0023fc6>] drm_mode_obj_set_property_ioctl+0x396/0x3b0 [drm] [<ffffffffa002400e>] drm_mode_connector_property_set_ioctl+0x2e/0x40 [drm] [<ffffffffa0013897>] drm_ioctl+0x1c7/0x5b0 [drm] [<ffffffffa01cd046>] radeon_drm_ioctl+0x46/0x80 [radeon] [<ffffffff811c3c9f>] do_vfs_ioctl+0x2cf/0x4b0 [<ffffffff811c3f01>] SyS_ioctl+0x81/0xa0 [<ffffffff815d0c2d>] system_call_fastpath+0x1a/0x1f [<00007ff15e493397>] 0x7ff15e493396 Code: 6b 40 44 8b b7 04 02 00 00 45 39 ee 0f 84 0c 01 00 00 48 85 db 44 89 af 04 02 00 00 0f 84 bc 01 00 00 48 8b 0b 41 bc 03 00 00 00 <48> 8b 91 10 03 00 00 48 81 c1 10 03 00 00 [ 132.533672] Kernel panic - not syncing: Watchdog detected hard LOCKUP on cpu 0 Kernel Offset: 0x0 from 0xffffffff81000000 (relocation range: 0xffffffff80000000-0xffffffff9fffffff) drm_kms_helper: panic occurred, switching back to text console Rebooting in 90 seconds.. The spot is drm_helper_choose_encoder_dpms(), and the connector_list seems broken. Another bug report shows a slightly different trace, and the spot it drm_crtc_helper_set_config(), list_for_each_entry(encoder, &dev->mode_config.encoder_list, head) { save_encoders[count++] = *encoder; } so encoder_list seems broken.

I noticed that all three reports above are with rv710, while my systems were newer ones (TURKS, ARUBA), so this issue might be specific to chip model. -- You are receiving this mail because: You are the assignee for the bug.

[PATCH v14 0/3] Add drm driver for Rockchip Socs
by Mark Yao 02 Dec '14

02 Dec '14

This a series of patches is a DRM Driver for Rockchip Socs, add support for vop devices. Future patches will add additional encoders/connectors, such as eDP, HDMI. The basic "crtc" for rockchip is a "VOP" - Video Output Processor. the vop devices found on Rockchip rk3288 Soc, rk3288 soc have two similar Vop devices. Vop devices support iommu mapping, we use dma-mapping API with ARM_DMA_USE_IOMMU. Changes in v2: - add DRM master device node to list all display nodes that comprise the graphics subsystem. - use the component framework to defer main drm driver probe until all VOP devices have been probed. - use dma-mapping API with ARM_DMA_USE_IOMMU, create dma mapping by master device and each vop device can shared the drm dma mapping. - use drm_crtc_init_with_planes and drm_universal_plane_init. - remove unnecessary middle layers. - add cursor set, move funcs to rockchip drm crtc. - add vop reset. Changes in v3: - change "crtc->fb" to "crtc->primary-fb" Adviced by Daniel Vetter - init cursor plane with universal api, remove unnecessary cursor set,move Changes in v4: Adviced by David Herrmann - remove drm_platform_*() usage, use register drm device directly. Adviced by Rob Clark - remove special mmap ioctl, do userspace mmap with normal mmap() or mmap offset Changes in v5: Adviced by Arnd Bergmann - doing DMA start with a 32-bit masks with dma_mask and dma_coherent_mark - fix some incorrect dependencies. Adviced by Boris BREZILLON - fix some mistake and bugs. Adviced by Daniel Vetter - drop all special ioctl and use generic kms ioctl instead. Adviced by Rob Clark - use unlocked api for drm_fb_helper_restore_fbdev_mode. - remove unused rockchip_gem_prime_import_sg_table. Changes in v6: - set gem buffer pitch 64 bytes align, needed by mali gpu. Adviced by Daniel Kurtz - fix some mistake, bugs, remove unused define, more better code style etc. - use clk_prepare()/unprepare() at probe()/remove() and clk_enable()/disable() at runtime instead of clk_prepare_enable(). - provide a help function from vop for encoder to do mode config, instead of using drm_diaplay_mode private method. - change vop mode_set timing to make it more safely. Changes in v7: - fix memory leakage problem. Changes in v8: - fix iommu crash when use dual crtc. - use frame start interrupt for vsync instead of line flag interrupt, because the win config take affect at frame start time, if we use ling flag interrupt, the address check often failed. Adviced by Daniel Kurtz - fix some bugs, mistake, remove unused function - keep clock and vop disabled when probe end - use drm_plane_helper_check_update to check update_plane if vaild Changes in v9: - fix suspend and resume bug, make iommu attach and detach safely. - fix mail info style. Changes in v10: Adviced by Andrzej Hajda - check drm_dev if it's NULL at PM suspend/resume Adviced by Sean Paul - use drm_fb_helper_prepare to init fb_helper funcs - Optimized code structure and remove some unnecessary Variables. Changes in v11: - fix mistake that use wrong variable at rockchip sys_resume/sys_suspend Changes in v12: - fix compile problem with drm-next - Optimization framebuffer reference/unreference - Optimization Code structure - fix pm suspend/resume problem - fix vblank irq can't close problem Changes in v13: - fix vop compile warning. Adviced by Daniel Vetter - directly call rockchip_drm_load before register instead of call ->load at the middle of drm register. Changes in v14: - revert v13 directly call rockchip_drm_load at bind, connector, crtc _init should before dev-node kms object lookup idr and conector sysfs need below minor node register, I don't like split the connector init and register, so just call ->load at the midile of drm register.

[PATCH 01/10] drm: add helper to get crtc timings (v5)
by Matt Roper 01 Dec '14

01 Dec '14

From: Gustavo Padovan <gustavo.padovan(a)collabora.co.uk> We need to get hdisplay and vdisplay in a few places so create a helper to make our job easier. Note that drm_crtc_check_viewport() and intel_modeset_pipe_config() were previously making adjustments for doublescan modes and vscan > 1 modes, which was incorrect. Using our new helper fixes this mistake. v2 (by Matt): Use new stereo doubling function (suggested by Ville) v3 (by Matt): - Add missing kerneldoc (Daniel) - Use drm_mode_copy() (Jani) v4 (by Matt): - Drop stereo doubling function again; add 'stereo only' flag to drm_mode_set_crtcinfo() instead (Ville) v5 (by Matt): - Note behavioral change in drm_crtc_check_viewport() and intel_modeset_pipe_config(). (Ander) - Describe new adjustment flags in drm_mode_set_crtcinfo()'s kerneldoc.

[Bug 73338] Fan speed in idle at 40% with radeonsi and at 18% with catalyst
by bugzilla-daemon＠freedesktop.org 01 Dec '14

01 Dec '14

https://bugs.freedesktop.org/show_bug.cgi?id=73338 --- Comment #59 from Alex Deucher <alexdeucher(a)gmail.com> --- (In reply to Chernovsky Oleg from comment #58) > Can you elaborate on what each bit of this control register means? Maybe I > just can't into abbreviations :) TMIN - temp at which the fan would be turned on FDO_PWM_MODE - which PWM mode to use: 0 - static PWM based on fuse value 1 - static PWM based on CG_FDO_CTRL0.FDO_STATIC_DUTY value 2 - dynamic PWM 5 - static PWM based on RPM CG_TACH_CTRL.TARGET_PERIOD value TACH_PWM_RESP_RATE - amount to adjust PWM in tach mode As far as I know, only values 1 and 5 are used for FDO_PWM_MODE in the driver for manual control. I'm not sure what dynamic PWM (2) means or how it works. It might be used by the smc for fan control. I also noticed a minor error in the RPM control setup, and I've pushed a patch to my 3.19-wip branch. -- You are receiving this mail because: You are the assignee for the bug.
