similar to: OpenGL context switching with Noveau

For details see my presentation on day 3 of XDC2016. TL;DW: A context switch on average takes ~25 microseconds, but depending on the display resolution and the load on the card times up to 130 microseconds have been observed. The average does not appear to differ much between cards as the (growing) size of the context is in balance with the increased DRAM bandwidth. Measured worst cases

Context switching = very slow on NVIDIA. Don't do it if you can avoid it. Each context is like a megabyte of data, if not more. Each time it has to get saved off and restored.

Dear Devs, We have achieved a desktop of up to six monitors, with openGL running succesfully on the desktop, with the following setup/features: * Ubuntu 16+ * Xrandr * Noveau driver * Two gtx750 graphic cards Each (identical) graphic card has 2xHDMI + 2xDVI connectors, which we connect to the monitor array. So far it works with six monitors, but we'd like to achieve eight. However,

Hi, Thanks for your advice..! I have a few follow-up questions (tagged below Q1, Q2 and Q3). Any help highly/extremely appreciated. Regarding to "reverse prime", etc. I have read the following page: https://nouveau.freedesktop.org/wiki/Optimus/ So, if we want a single "macro" xscreen that spans two cards, for example: Card 0, connected to monitor 0 Card 1, connected to

Hi I am relatively new to ruby on rails. I want to use this javascript bundle: http://prototype-window.xilinus.com/index.html How would I call those functions in an rjs file? example: win = new Window(''window_id'', {title: "Sample", top:100, left:350}) win.getContent().innerHTML = "<h1>Hello world !!</h1>"; win.setDestroyOnClose();

Hello, Is it possible to produce machine code directly to memory buffer so that it could be called immediately? What I would like to do is something like this: Compiler: Scripting language (Antlr) -> LLVM IR -> (Optimization) -> Raw Machine code -> (Transport media) -> Execution The idea is that I could compile my scripts directly to asm without any extra steps and in

It seems common to use RJS for quickly adding and highlighting a list that is having content added to it like this: http://rafb.net/paste/results/Z3m32g48.html ... where "my_list" would be an UL and the partial would insert a LI. Given that example, is there an easy way to highlight only the newly inserted LI instead of the whole UL? The only way I can see to do it is to give

Hi All, I'm experiencing odd behaviour with various OpenGL apps I'm (trying to) use. I have an IBM Thinkpad X60s with the Intel GMA chipset, the 945GM to be precise. I have glxinfo/glxgears working normally, disabled composite in xorg.conf and everything seems fine. However, there are a few applications that I use that show rather strange behaviour that I think is related to the same

Hey Attila, I CC'd the nouveau mailing list. Although if you want help, you should probably provide more details (what version of mesa, etc.).

nv50_disp_atomic_commit() calls calls pm_runtime_get_sync and in turn increments the reference count. In case of failure, decrement the ref count before returning the error.

Hi, Turning off a connected TV, and then turning it on causes issues with re-negotiating a connection to the display. The error message was pasted into an open document that was actively under edit with the program nano. I assume messages are sent from somewhere destined for stdout; or something has redirected it. Either way, I think this may cause issues with bug reports. It looks like a dmesg

OK, I give up and come grovelling, "Fork" was suggested at 18:23, it's now 22:20 and I have been through 4 different methods, all block with a 2 second delay before returning to dialplan. Here are just some of the examples I have tried, as as per the suggestions, I am closing all possible outputs in the forked process. https://docs.python.org/3.5/library/multiprocessing.html

Thanks for the pointer. But I don't like this patch. If you find a bug, make a bug report or just fix it if you know the fix already. Or write something in IRC. Or write on the Mailing list as a general question or something else But I really don't agree on doing it this way. You would have needed like the same amount of time to actual fix the problem. Anyway, for adding a printk:
