Andreas Sandberg 14b8a17f28 dev: Clean up MC146818 register (A & B) handling 
Rewrite reg A & B handling to use the bitunion stuff instead of bit
masking. Add better error messages when the kernel tries to enable
unsupported stuff.

Ali Saidi 3876105bdb ARM: Add RTC device for ARM platforms. 
This change implements a PL031 real time clock.

--HG--
rename : src/dev/arm/timer_sp804.cc => src/dev/arm/rtc_pl031.cc
rename : src/dev/arm/timer_sp804.hh => src/dev/arm/rtc_pl031.hh

Nilay Vaish b61e34fab8 mc146818: Correctly serialize tickEvent 
'tickEvent' was not being serialized as in its place 'event' was being used.
This patch rectifies this error.

Nathan Binkert eddac53ff6 trace: reimplement the DTRACE function so it doesn't use a vector 
At the same time, rename the trace flags to debug flags since they
have broader usage than simply tracing.  This means that
--trace-flags is now --debug-flags and --trace-help is now --debug-help

Steve Reinhardt 6f1187943c Replace curTick global variable with accessor functions. 
This step makes it easy to replace the accessor functions
(which still access a global variable) with ones that access
per-thread curTick values.

Steve Reinhardt 3f9f4bf3d6 devices: undo cset 017baf09599f that added timer drain functions. 
It's not the right fix for the checkpoint deadlock problem
Brad was having, and creates another bug where the system can
deadlock on restore.  Brad can't reproduce the original bug
right now, so we'll wait until it arises again and then try
to fix it the right way then.

Brad Beckmann 283be34a99 devices: Fixed periodic interrupts to work with draining 
Added drain functions to the RTC and 8254 timer so that periodic interrupts
stop when the system is draining.  This patch is needed to checkpoint in
timing mode.  Otherwise under certain situations, the event queue will never
be completely empty.

Brad Beckmann 28204b2a96 fixed MC146818 checkpointing bug and added isa serialization calls to simple_thread 2009-10-15 15:15:24 -07:00
Gabe Black f6bb7ec4eb RTC: Make calls to writeData update the RTCs internal representation of time. 2009-08-20 23:09:03 -07:00

Gabe Black bc67396ada X86: Don't insist on binary encoding for the RTC since we implement BCD. 2009-08-20 00:40:14 -07:00
Gabe Black 4a64493158 Devices: Make the RTC device reflect the use of BCD in its status registers. 2009-02-25 10:22:49 -08:00
Gabe Black 919c3e7fb6 Dev: Make the RTC device ignore writes to a read only bit. 2009-01-25 20:32:26 -08:00
Nathan Binkert e06321091d eventq: convert all usage of events to use the new API. 
For now, there is still a single global event queue, but this is
necessary for making the steps towards a parallelized m5.

Gabe Black e5bdae15f3 Devices: Separate out the MC146818 RTC so both Alpha and X86 can use it.
