[Bug 107183] Enabling Glamor takes half a second
https://bugs.freedesktop.org/show_bug.cgi?id=107183 --- Comment #5 from Paul Menzel --- Michel, Chris, I just noticed, that the delay is only there when starting the X.Org X server for the first time. Could you please make sure, that your systems are rebooted when trying this? (During my tests I do not use a graphical login manager, and just log in on a terminal and execute `exec startx`.) -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

https://bugs.freedesktop.org/show_bug.cgi?id=107183 --- Comment #4 from Paul Menzel --- I tested this with an older Intel based Dell OptiPlex 7010, also with Debian Sid/unstable (Linux 4.17.3-1, and xserver-xorg-core 2:1.20.0-3) and an HDD – the other system has an SSD, the delay is with 1.8 seconds even bigger. ``` [26.041] (II) modeset(0): Creating default Display subsection in Screen section "Default Screen Section" for depth/fbbpp 24/32 [26.041] (==) modeset(0): Depth 24, (==) framebuffer bpp 32 [26.041] (==) modeset(0): RGB weight 888 [26.041] (==) modeset(0): Default visual is TrueColor [26.041] (II) Loading sub module "glamoregl" [26.041] (II) LoadModule: "glamoregl" [26.068] (II) Loading /usr/lib/xorg/modules/libglamoregl.so [26.253] (II) Module glamoregl: vendor="X.Org Foundation" [26.253]compiled for 1.20.0, module version = 1.0.1 [26.253]ABI class: X.Org ANSI C Emulation, version 0.4 [28.009] (II) modeset(0): glamor X acceleration enabled on Mesa DRI Intel(R) Ivybridge Desktop [28.009] (II) modeset(0): glamor initialized ``` Looking at the messages though, *loalding* the module takes 200 ms. “Running it” takes long.

--- Comment #3 from Chris Wilson ---
Fwiw, a few years ago, dlopen("libGL.so") took on the order of a second on a
laptop HDD, which could be eliminated by prelinking. It might worth checking
the exported symbol tables (objdump -T ?) to see if they are unnecessarily
cumbersome.

https://bugs.freedesktop.org/show_bug.cgi?id=107183 --- Comment #2 from Paul Menzel --- (In reply to Michel Dänzer from comment #1) > FWIW, this only takes a few milliseconds on my systems. Thank you for testing that. Could you please list the details for one of these systems (hardware, Linux version, X server versions, …)? > You'd have to profile where the time is spent on your system, but it's more > likely somewhere between glamor and Mesa / LLVM than in the kernel. Interesting. Is there a debug switch for the module glamoregl or do I need to use something like `perf` or `oprofile`? -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
