[PATCH 0/6] drm/meson: add support for AXG & MIPI-DSI
by Neil Armstrong 20 Jan '22

20 Jan '22

The Amlogic AXG SoC family has a downgraded VPU with the following changes : - Only a single OSD plane, no overlay video plane - The primary plane doesn't support HW scaling - The pixels are read directly from DDR without any Canvas module - Doesn't support HDMI or CVBS - Ouputs only with ENCL encoder to a DPI-to-DSI Synopsys DW-MIPI-DSI transceiver The Amlogic AXg SoCs embeds a Synopsys DW-MIPI-DSI transceiver (ver 1.21a), with a custom glue managing the IP resets, clock and data input similar to the DW-HDMI Glue on other Amlogic SoCs. This adds support for the Glue managing the transceiver, mimicing the init flow provided by Amlogic to setup the ENCl encoder, the glue, the transceiver, the digital D-PHY and the Analog PHY in the proper way. The DW-MIPI-DSI transceiver + D-PHY are directly clocked by the VCLK2 clock, which pixel clock is derived and feeds the ENCL encoder and the VIU pixel reader. An optional "MEAS" clock can be enabled to measure the delay between each vsync feeding the DW-MIPI-DSI transceiver.

[Bug 53391] New: nouveau: wrong display output order

08 Dec '21

https://bugzilla.kernel.org/show_bug.cgi?id=53391 Summary: nouveau: wrong display output order Product: Drivers Version: 2.5 Kernel Version: 3.8-rc6 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri(a)kernel-bugs.osdl.org ReportedBy: stijn+bugs(a)linux-ipv6.be Regression: No My graphics card is a Gainward GTX480 (http://www.gainward.com/main/vgapro.php?id=238). It has 2 DVI outputs, and 1 mini HDMI output. The DVI outputs are numbered on the card, with DVI 1 being the closest to the PCIe slot, then DVI 2, and finally the mini HDMI. My primary (left) monitor, is connected to DVI 1, my secondary (right) monitor to DVI 2. When I boot the computer, the BIOS initializes and uses the monitor on DVI 1. Grub is displayed on the primary monitor, and the kernel initially outputs to the primary monitor as well. However, as soon as the nouveau module is loaded, the primary monitor goes to standby and the kernel now uses the secondary monitor (on DVI 2) as primary. When X starts (no Xorg.conf file), it is also displayed on the secondary monitor. When using either efifb, vesafb or uvesafb, the monitor on DVI 1 is always the primary monitor. X with nvidia.ko also uses DVI 1 as the primary display. Finally, when booting Windows, the startup screen is also displayed on the monitor connected to DVI 1. Here comes the weird part: when I am in X, and run xrandr, it does show 3 connected devices: DVI-I-1, DVI-I-2, and HDMI-1, with DVI-I-2 being the only active one. So it seems that in X, the output order is correct, but with nouveaufb the DVI connectors are swapped. I will attach the output of dmesg here. If anything else is needed, please let me know and I'll be happy to add it. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
