Subject: [REGRESSION] drm/amd/display: Add an hdmi_hpd_debounce_delay_ms
module
Hi,
I hit a regression introduced as part of v6.19-rc6 (and still present
in v6.19-rc7), where, upon unloading the amdgpu module, __flush_work()
is passed a work struct with the work function set to NULL. The issue
is seen with an AMD Radeon Pro W7900, but not an AMD Instinct MI210.
#regzbot introduced: d04f73668bebbc5a44a2771ea92b6ec253148050
4231 static bool __flush_work(struct work_struct *work, bool from_cancel)
4232 {
4233 struct wq_barrier barr;
4234
4235 if (WARN_ON(!wq_online))
4236 return false;
4237
--> 4238 if (WARN_ON(!work->func))
4239 return false;
Tests were carried out on an AMD Radeon Pro W7900 with a mainline
kernel compiled and booted with an up-to-date CentOS Stream 10 x86_64
and amdgpu firmware commit 993573ac3dc6ab038505c2639701db22f6142487.
% cp /lib/modules/6.12.0-191.el10.x86_64/config .config
% scripts/config --enable LOCALVERSION_AUTO
% scripts/config --disable EFI_SBAT_FILE
% scripts/config --disable SECURITY_LOCKDOWN_LSM
% scripts/config --disable MODULE_SIG
% make olddefconfig
% make -j $(nproc) binrpm-pkg
The first test exercises commit d04f73668beb which introduced the
regression, the second test b2426a211dba prior to the regression.
