Title:
When stressed by a load of clients starting at once: Failed to get
PRIME fd from gbm bo
Status in Mir:
Fix Committed
Status in mir package in Ubuntu:
New
Bug description:
I initially found this with miral-shell, but found similar behaviour
with mir_demo_shell_minimal.
Start a shell, then start all the mir_demo_client_XXX apps. (For
convenience see attached script.)
Then start closing apps one by one: At some point the server dies with
a segfault.
With a bit of debugging I managed to catch the following error just
before the segfault:
ERROR:
/home/alan/display_server/mir/src/platforms/mesa/server/buffer_allocator.cpp(150):
Throw in function virtual void
{anonymous}::DMABufTextureBinder::ensure_egl_image()
Dynamic exception type:
boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::system_error>
>
std::exception::what: Failed to get PRIME fd from gbm bo: No such file or
directory
