Subject: MIPS: Kernel hangs occasionally during boot.
|
||||
Date: Tue, 08 Nov 2011 13:59:01 -0000
|
||||

||||

||||
Message-Id: <1320764341-4275-1-git-send-email-alcooperx@gmail.com>

|
||||
|
||||
The Kernel hangs occasionally during boot after
|
||||
"Calibrating delay loop..". This is caused by the
|
||||
c0_compare_int_usable() routine in cevt-r4k.c returning false which
|
||||
causes the system to disable the timer and hang later. The false
|
||||
return happens because the routine is using a series of four calls to
|
||||
irq_disable_hazard() as a delay while it waits for the timer changes
|
||||
to propagate to the cp0 cause register. On newer MIPS cores, like the 74K,
|
||||
the series of irq_disable_hazard() calls turn into ehb instructions and
|
||||
can take as little as a few clock ticks for all 4 instructions. This
|
||||
is not enough of a delay, so the routine thinks the timer is not working.
|
||||
This fix uses up to a max number of cycle counter ticks for the delay
|
||||
and uses back_to_back_c0_hazard() instead of irq_disable_hazard() to
|
||||
handle the hazard condition between cp0 writes and cp0 reads.
