| alan_g | alf__: IIRC the mesa support did/does some unusual stuff with loading symbols? | 11:56 |
|---|---|---|
| anpok | i think the interesting part is that the mesa egl library does not link against mirclient | 11:58 |
| anpok | (while it links against wayland c/s and libX*) | 11:59 |
| anpok | alan_g: mesa does lib = dlopen(null) dlsym(.. "mir_egl_mesa_display_is_valid") .. | 12:00 |
| alan_g | anpok: Ah. That's probably what I'm seeing. | 12:01 |
| alf__ | alan_g: anpok: yes, it assumes that libmirclient/server is linked by the executable, and searches for that function at runtime | 12:01 |
| alan_g | I tried removing the ensure_loaded_with_rtld_global() hack and mesa "blew up" | 12:02 |
| anpok | then it knows that the surface is of a specific type and uses function pointers there to advance buffers.. | 12:02 |
| anpok | ah | 12:02 |

| alan_g | alf__: @1455109 - so we change status to confirmed? And push to the kernel team? | 14:44 |
| alf__ | alan_g: that's one way to go, although I still haven't verified that the commit really fixes the problem. | 14:47 |
| alan_g | alf__: OK, then just update the status for now? | 14:47 |
| alf__ | alan_g: yes | 14:48 |
| * alan_g is glad that all the cleanup of linkage to static libraries allows us to remove the ensure_loaded_with_rtld_global() hack from libmirclient and libmirplatform | 14:51 | |
| alf__ | alan_g: I will mark confirmed in Mir for now, although the kernel crash is of course the kernel's fault. | 14:52 |
| alf__ | alan_g: Not sure what's so special about "sudo mir_demo_server --vt 2 --test-timeout 1 --test-client mir_demo_client_basic" | 14:52 |
| alf__ | alan_g: the command also fails on radeon too (but doesn't crash the kernel) | 14:52 |
| alan_g | Indeed, especially as I couldn't get the error with the non-installed build (even with use_debflags) | 14:53 |
| alan_g | davmor2: not nagging, but what timeframe are we expecting for mir-0.13.0? | 15:27 |
| davmor2 | alan_g: I have been blocked for 2 days and the fubar images in the channels so it should be by end of day today hopefully | 15:28 |
| davmor2 | s/and/with | 15:28 |
| alan_g | Thanks. :) | 15:29 |
| davmor2 | now that we finally have vivid images all round | 15:29 |
