The VDPU at RK3328 is a standalone decoder IP without
encoder. Also there is the other AVS+ decoder IP,
working as the combo IP.
I introduce the following commit from develop-3.10,
commit ee2f9f6912fb ("rk322xh/vcodec: bugfix, avoid combo device overwrite irq status")
commit 568dabeb12ef ("rockchip/vcodec: bugfix, inconsistence power on/off operation")
The following patches have not been introduced,
it would effect RKV device:
commit b8a2ce7e5b60 ("rockchip/vcodec: disable power-save optimization for hw defeat")
commit 046faf9ba20a ("rk322xh/vcodec: bugfix, probe failed when ion cma heap undefined")
commit beaeb230cbf2 ("rk322xh/vcodec: revise for rk322xh feature")

As dmc may also assess register PMU_BUS_IDLE_REQ, we should prevent
pd driver and dmc driver assessing this register at the same time.

This function registers a notifier to dmc devfreq, it will lock the mutex
of pmu when scaling frequency, so that pd driver and dmc driver will not
assess register PMU_BUS_IDLE_REQ at the same time.

Compiling the DT file with W=1, DTC warns like follows:
Warning (unit_address_vs_reg): Node /opp_table0/opp@1000000000 has a
unit name, but no reg property
Fix this by replacing '@' with '-' as the OPP nodes will never have a
"reg" property.

commit 34a477e529 upstream.
On x86-32, with CONFIG_FIRMWARE and multiple CPUs, if you enable function
graph tracing and then suspend to RAM, it will triple fault and reboot when
it resumes.
The first fault happens when booting a secondary CPU:
startup_32_smp()
load_ucode_ap()
prepare_ftrace_return()
ftrace_graph_is_dead()
(accesses 'kill_ftrace_graph')
The early head_32.S code calls into load_ucode_ap(), which has an an
ftrace hook, so it calls prepare_ftrace_return(), which calls
ftrace_graph_is_dead(), which tries to access the global
'kill_ftrace_graph' variable with a virtual address, causing a fault
because the CPU is still in real mode.
The fix is to add a check in prepare_ftrace_return() to make sure it's
running in protected mode before continuing. The check makes sure the
stack pointer is a virtual kernel address. It's a bit of a hack, but
it's not very intrusive and it works well enough.
For reference, here are a few other (more difficult) ways this could
have potentially been fixed:
- Move startup_32_smp()'s call to load_ucode_ap() down to *after* paging
is enabled. (No idea what that would break.)
- Track down load_ucode_ap()'s entire callee tree and mark all the
functions 'notrace'. (Probably not realistic.)
- Pause graph tracing in ftrace_suspend_notifier_call() or bringup_cpu()
or __cpu_up(), and ensure that the pause facility can be queried from
real mode.
