Dmesg

Hi,

I've been seeying SIGSEGV MAPERR with radeonsi (HD7750 and HD7950)
It can be triggered in various situations/primitives,
like EGLSwapBuffersWithDamage, EGLterminate and others,
but the crash has always the same outcome and backtrace.

I think it is important to highlight that the issue started happening with
nougat, which uses multiple threads/render threads, as opposed to marshmallow
which was using single threading and it is not affected.

Now this may have exposed a non thread safe path in radeonsi code,
because other drivers (intel, nouveau with Ilia's draft locking patches)
are not affected by this issue.

Dmesg, Logcat and addr2line log in the attachments
Available to provide further info and to test patches, if needed.
Mauro

Hi,

the problem has disappeared in the last week,
I've seen a series of commits for radeonsi,
but could some developer point out what changes have been done,

which may have corrected a NULL pointer dereference MAPERR at address 0x0 
happening at list_add after a destroy_buffer_locked?

Besides closing this bug, the information is important in order to backport bug
corrections in mesa 17.0.x and mesa 13.0.x

--- Comment #5 from Mauro Rossi <issor.oruam@gmail.com> ---
In the previous post is what happened with x86_64 nougat-x86 build, for all
mesa 17.0.x cycle.

Here follows what still happens with mesa 17.0.3 with x86 build of nougat-x86.
I hope by coupling these information of x86_64 and x86 build may help to figure
out the issue.

Hi,

commit ce27b27 "radeon: initialize hole variable before calling container_of"
solves the issue and should be backported to mesa 13.0 and mesa 17.0 branches
to have this bug resolved in next maintenance releases.

Tested with nougat-x86 on HD7750 and HD7950

Mauro
