[Bug 99683] Powerplay features request: manually set GPU (Fiji) frequency beyond default limits and per application
by bugzilla-daemon＠freedesktop.org 06 Feb '17

06 Feb '17

https://bugs.freedesktop.org/show_bug.cgi?id=99683 Bug ID: 99683 Summary: Powerplay features request: manually set GPU (Fiji) frequency beyond default limits and per application Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: All Status: NEW Severity: enhancement Priority: medium Component: DRM/Radeon Assignee: dri-devel(a)lists.freedesktop.org Reporter: bug0xa3d2(a)hushmail.com My R9 Nano is watercooled and does not get hot even when operating at 1000mhz, its' max frequency. 1) I request the ability to manually set the frequency beyond 1000mhz. 2) I would like the ability to have user determined frequencies to automatically be applied per application or process as well. For example: I set somewhere that the GPU runs DOTA2 at 1200mhz until the game process ends. -- You are receiving this mail because: You are the assignee for the bug.

And it's look like this five patches are in 12 and not in 11.2.

[PATCH V7 0/4] Add driver for GE B850v3 LVDS/DP++ Bridge
by Peter Senna Tschudin 06 Feb '17

06 Feb '17

The series adds a driver that creates a drm_bridge and a drm_connector for the LVDS to DP++ display bridge of the GE B850v3. There are two physical bridges on the video signal pipeline: a STDP4028(LVDS to DP) and a STDP2690(DP to DP++). The hardware and firmware made it complicated for this binding to comprise two device tree nodes, as the design goal is to configure both bridges based on the LVDS signal, which leave the driver powerless to control the video processing pipeline. The two bridges behaves as a single bridge, and the driver is only needed for telling the host about EDID / HPD, and for giving the host powers to ack interrupts. The video signal pipeline is as follows: Host -> LVDS|--(STDP4028)--|DP -> DP|--(STDP2690)--|DP++ -> Video output This series depends on commit dc80d7038883 ("drm/imx-ldb: Add support to drm-bridge") which is already on linux-next. The patches from the series: [1/4] Devicetree documentation for the GE B850v3 LVDS/DP++ Bridge [2/4] Update the MAINTAINERS file [3/4] Add the driver, make changes to Kconfig and Makefile [4/4] Make the changes to the B850v3 dts file to enable the GE B850v3 LVDS/DP++ Bridge. Tested on next20161224. Changes from V6: - Removed check for pixel clock as the bridge supports up to 330Mhz while the host is limited to 264 MHz in very specific conditions. - Added a second mutex to avoid concurrency issues while acking interrupts from threaded interrupt handlers. - Renamed the edid mutex to be more descriptive. - Added a .detach() function that disables the interrupts. - Adopted i2c_new_secondary_device() and updated the dts and documentation to match the new method. - Removed useless test to drm_bridge_add() - Did some refactoring around devm_request_threaded_irq() - Added a missing call to i2c_unregister_device() on the i2c_driver.remove() function. Changes from V5: - Change to MAINTAINERS in a separate patch - Reworked interrupt handler initialization - Removed useless calls to: drm_connector_register(), drm_helper_hpd_irq_event(), and drm_bridge_enable() Changes from V4: - Renamed the i2c_driver.name from "ge,b850v3-lvds-dp" to "b850v3-lvds-dp" to remove the comma from the driver name Changes from V3: - Removed the patch that was configuring the mapping between IPUs and external displays on the dts file Peter Senna Tschudin (4): Documentation/devicetree/bindings: b850v3_lvds_dp MAINTAINERS: Add entry for GE B850v3 LVDS/DP++ Bridge drm/bridge: Add driver for GE B850v3 LVDS/DP++ Bridge dts/imx6q-b850v3: Use GE B850v3 LVDS/DP++ Bridge .../devicetree/bindings/ge/b850v3-lvds-dp.txt | 39 +++ MAINTAINERS | 8 + arch/arm/boot/dts/imx6q-b850v3.dts | 30 ++ drivers/gpu/drm/bridge/Kconfig | 11 + drivers/gpu/drm/bridge/Makefile | 1 + drivers/gpu/drm/bridge/ge_b850v3_lvds_dp.c | 384 +++++++++++++++++++++ 6 files changed, 473 insertions(+) create mode 100644 Documentation/devicetree/bindings/ge/b850v3-lvds-dp.txt create mode 100644 drivers/gpu/drm/bridge/ge_b850v3_lvds_dp.c -- 2.5.5

[PATCH v17 0/7] drm/rockchip: Add CDN DP driver
by Chris Zhong 05 Feb '17

05 Feb '17

This series adds support for the CDN DP controller to the rockchip drm driver. This version fixes some coding style error in v16, it post by Sean Paul, you can find it here: https://patchwork.kernel.org/patch/9442135/ And I sorted out a few patches to fix the following problems: - suspend/resume crash cause by drm_helper_hpd_irq_event - crash during shutdown when cdn-dp failed to bind - check sink count failed after reconnection - suspend/reusme crash in mode_set function I also added these 2 patches to this series, although nothing changed: https://patchwork.kernel.org/patch/9442141/ https://patchwork.kernel.org/patch/9442151/ Changes in v17: - Correct the clock check condition - Correct the coding style - change LANE_REF_CYC to 0x8000 Chris Zhong (4): drm/rockchip: cdn-dp: add cdn DP support for rk3399 drm/rockchip: cdn-dp: do not use drm_helper_hpd_irq_event drm/rockchip: cdn-dp: retry to check sink count drm/rockchip: cdn-dp: don't configure hardware in mode_set Guenter Roeck (2): drm/rockchip: cdn-dp: Load firmware if no monitor connected drm/rockchip: cdn-dp: Do not run worker while suspended Jeffy Chen (1): drm/rockchip: cdn-dp: Move mutex_init to probe drivers/gpu/drm/rockchip/Kconfig | 10 + drivers/gpu/drm/rockchip/Makefile | 2 + drivers/gpu/drm/rockchip/cdn-dp-core.c | 1260 +++++++++++++++++++++++++++ drivers/gpu/drm/rockchip/cdn-dp-core.h | 112 +++ drivers/gpu/drm/rockchip/cdn-dp-reg.c | 979 +++++++++++++++++++++ drivers/gpu/drm/rockchip/cdn-dp-reg.h | 483 ++++++++++ drivers/gpu/drm/rockchip/rockchip_drm_vop.c | 13 +- drivers/gpu/drm/rockchip/rockchip_drm_vop.h | 9 + drivers/gpu/drm/rockchip/rockchip_vop_reg.c | 2 + 9 files changed, 2867 insertions(+), 3 deletions(-) create mode 100644 drivers/gpu/drm/rockchip/cdn-dp-core.c create mode 100644 drivers/gpu/drm/rockchip/cdn-dp-core.h create mode 100644 drivers/gpu/drm/rockchip/cdn-dp-reg.c create mode 100644 drivers/gpu/drm/rockchip/cdn-dp-reg.h -- 2.6.3

[PATCH v3 0/5] Rockchip dw-mipi-dsi driver
by Chris Zhong 05 Feb '17

05 Feb '17

Hi all This patch serial is for RK3399 MIPI DSI. The MIPI DSI controller of RK3399 is almost the same as RK3288, except a little bit of difference in phy clock controlling and port id selection register. These patches add RK3399 support and the power domain support. And these patches base on John Keeping's series[0], it fixes many bugs, they have been tested on rk3288 evb board.

[RFCv2 PATCH 0/5] CEC drivers for iMX6 and TDA9950
by Hans Verkuil 05 Feb '17

05 Feb '17

From: Hans Verkuil <hans.verkuil(a)cisco.com> This patch series is an update to this RFC series from Russell: https://lists.freedesktop.org/archives/dri-devel/2016-August/115733.html I have not seen any updates to this, so I hope that that series is still the latest version. The main problem with that original series was that the notifier didn't store the state, so if a CEC driver registered with the notifier, then it wouldn't be informed of the current state. The hdmi-notifier code has been changed to a per-HDMI-device and refcounted block_notifier that stores the state and will report the current state upon registration. The other four patches have been adapted to the new notifier code, but no other changes were made. It has *only* been compile-tested. I might be able to verify it next week with an actual i.MX6 device, but it will take time to set that up. If someone has a ready-to-test setup, then I would very much appreciate it if this series can be tested. The patches are also available in my branch: https://git.linuxtv.org/hverkuil/media_tree.git/log/?h=cec-notifiers It is on top of my patch series that moves CEC out of staging. This is planned for 4.10.
