Subject: MIPS: Kernel hangs occasionally during boot.
Date: Tue, 08 Nov 2011 13:59:01 -0000
From: Al Cooper <alcooperx@gmail.com>
X-Patchwork-Id: 2911
Message-Id: <1320764341-4275-1-git-send-email-alcooperx@gmail.com>
To: ralf@linux-mips.org, linux-mips@linux-mips.org,
linux-kernel@vger.kernel.org
Cc: "Al Cooper" <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.
