If you make a decision to program the hardware in a certain way, you
must make sure that hardware programming operation occurs atomically.

This could be because it takes multiple register writes to perform
the operation and they are dependent upon eachother, or you are
makeing multiple modifications which must occur in a certain
sequence.

If you allow these ->mac->xxx calls to run in parallel with eachother
I guarantee it will cause problems.

Stop brushing it off as a non-issue, unless you want your driver
to mysteriously not work when the race is triggered.

Thanks for your reply. I'm sorry i was too busy to solve some other
problems last few weeks that i can not reply in time.

I can't quite seize David's meaing whether the ->mac->xxx should inside the
lock or outside the lock.
In my opinion, the ->mac->xxx calls did not operate any shared data or
struct. The calls just control the hardware by write data to registers.
So  ->mac->xxx calls  can be removed from lock.

So i think descriptors operation might be the only part that should be
locked.

Hao Liang

It's preventing parallel invocations of the ->mac->xxx calls.

The other instances are in device open/close, where RTNL semaphore is
held, and no other code paths in the driver can be active.

You need the lock.

Hi David,

I double-check my patch and the ->mac->xxx calls are still under the lock.
I think that lock is trying to protect priv struct and related data, so i
just remove some functions have no bearing on priv struct.

I really think the ->mac->xxx calls need to be under the lock, and therefore this
spinlock region shortening is not valid.

I had done something in this patch:
    [PATCH (net.git)] stmmac: fix and review whole driver locking

Indeed I was not able to review it after some advice but I will do it!

So we can review your patch and then I will re-base my work on top of
yours.

I just wonder if the spinlock can be safely removed instead of
surrounding just the code to clear the descriptors that should
not be claimed by others. Maybe the only part shared is the
stmmac_hw_setup that can be invoked by open method.

[Adi-linux-docs] [PATCH] net: ethernet : stmicro: fixed power suspend and resume failure in stmmac driver

[<hli...@gm...>]

From: Hao Liang <hli...@gm...>

This is the fix for a power management issue caused by suspend and resume function in stmmac_main.c.
After enable CONFIG_DEBUG_ATOMIC_SLEEP which enable sleep-inside atomic section checking, power
managemet can not work normally. Board couldn't wakeup successfully after suspend. Command
"echo mem > /sys/power/state" suspend the board.

In suspend and resume function of stmmac driver, there are some sleep-inside function in atomic section
created by spin lock. These functions will causes system warnings and wakeup issue when enable
CONFIG_DEBUG_ATOMIC_SLEEP.

This bug was fixed by:
* replace some sleep function with non-sleep function
  clk_disable_unprepare -> clk_disable ...
* decrease the atomic area created by spin lock function. The original atomic area in resume function is
too large.
