2011-05-13ARM: Better RealView/Versatile EB platform support.Chander Sudanthi
Add registers and components to better support the VersatileEB board. Made the MIDR and SYS_ID register parameters to ArmSystem and RealviewCtrl respectively.
2011-05-04ARM: Make GIC handle IPIs and multiple processors.Prakash Ramrakhyani
2011-05-04ARM: Add snoop control unit device.Ali Saidi
2011-05-04ARM: Add support for some more registers in the real view controller.Ali Saidi
2011-05-04RealView: Fix the 24 and 100MHz clocks which were providing incorrect values.Chris Emmons
2011-04-20fix some build problems from prior changesetsNathan Binkert
2011-04-15trace: reimplement the DTRACE function so it doesn't use a vectorNathan Binkert
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

2011-03-17Mem: Fix issue with dirty block being lost when entire block transferred to ↵Ali Saidi
non-cache. This change fixes the problem for all the cases we actively use. If you want to try more creative I/O device attachments (E.g. sharing an L2), this won't work. You would need another level of caching between the I/O device and the cache (which you actually need anyway with our current code to make sure writes propagate). This is required so that you can mark the cache in between as top level and it won't try to send ownership of a block to the I/O device. Asserts have been added that should catch any issues.
2011-02-23Includes: Don't include isa_traits.hh and use the TheISA namespace unless ↵Ali Saidi
really needed.
2011-02-23CLCD: Fix some serialization bugs with the clcd controller.Ali Saidi
2011-02-23ARM: Add support for read of 100MHz clock in system controller.Ali Saidi
2011-02-11VNC/ARM: Use VNC server and add support to boot into X11Ali Saidi
2011-02-11ARM: Fix timer calculations.Ali Saidi
The timer calculations were a bit off so time would run faster than it otherwise should
2011-02-06dev: fixed bugs to extend interrupt capability beyond 15 coresBrad Beckmann
2011-02-06x86: Add checkpointing capability to devicesJoel Hestness
Add checkpointing capability to the Intel 8254 timer, CMOS, I8042, PS2 Keyboard and Mouse, I82094AA, I8237, I8254, I8259, and speaker devices
2011-02-06MessagePort: implement the virtual recvTiming function to avoid double pkt ↵Joel Hestness
delete Double packet delete problem is due to an interrupt device deleting a packet that the SimpleTimingPort also deletes. Since MessagePort descends from SimpleTimingPort, simply reimplement the failing code from SimpleTimingPort: recvTiming.
2011-01-07Replace curTick global variable with accessor functions.Steve Reinhardt
This step makes it easy to replace the accessor functions (which still access a global variable) with ones that access per-thread curTick values.
2011-01-03Make commenting on close namespace brackets consistent.Steve Reinhardt
Ran all the source files through 'perl -pi' with this script: s|\s*(};?\s*)?/\*\s*(end\s*)?namespace\s*(\S+)\s*\*/(\s*})?|} // namespace $3|; s|\s*};?\s*//\s*(end\s*)?namespace\s*(\S+)\s*|} // namespace $2\n|; s|\s*};?\s*//\s*(\S+)\s*namespace\s*|} // namespace $1\n|; Also did a little manual editing on some of the arch/*/isa_traits.hh files and src/SConscript.
2010-12-20Style: Replace some tabs with spaces.Gabe Black
2010-11-26IGbE: return 0 on an invalid descriptor size instead of -1.Ali Saidi
Asserts where descSize() get called with assert if we end up returning 0.
2010-11-22IDE,X86: Fix IDE controller BAR configuration for x86.Gabe Black

2010-11-15ARM: Add support for a dumb IDE controllerAli Saidi
2010-11-08ARM: Add checkpointing supportAli Saidi
2010-11-08ARM: Keep the warnings to a minimum.Ali Saidi
These warnings still need to be addresses, but pages of them is counterproductive.
2010-11-08Bus: Have the I/O devices that return address ranges print them out.Ali Saidi
This way we actually get device names associated with the devices.
2010-11-08sim: Use forward declarations for ports.Ali Saidi
Virtual ports need TLB data which means anything touching a file in the arch directory rebuilds any file that includes system.hh which in everything.
2010-10-17MIPS: Get rid of the backdoor device copy/pasted from and only used in Alpha.Gabe Black
2010-10-09UART: Make the 8250's MCR return a deterministic value.Gabe Black
This change makes the 8250 device return the value it has for the MCR when read instead of leaving the packet data unmodified/uninitialized. The value the UART has for the MCR may not be right, but that's a seperate issue that apparently hasn't caused any problems to date.
2010-10-01ARM: Add a fake flash controller so that unmodified linux can bootAli Saidi
With this change an unmodified Linux kernel can boot in M5.
2010-10-01ARM: Fix some subtle bugs in the GICPrakash Ramrakhyani
The GIC code can write to the registers with 8, 16, or 32 byte accesses which could set/clear different numbers of interrupts.
2010-09-16devices: undo cset 017baf09599f that added timer drain functions.Steve Reinhardt
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.
2010-09-10style: fix sorting of includes and whitespace in some filesNathan Binkert
2010-08-23Devices: Allow a device to specify that a request is uncachable.Gene Wu
2010-08-23ARM: Change how the AMBA device ID checking is done to make it more genericAli Saidi
2010-08-23ARM: Add I/O devices for booting linuxAli Saidi
--HG-- rename : src/dev/arm/Versatile.py => src/dev/arm/RealView.py rename : src/dev/arm/versatile.cc => src/dev/arm/realview.cc rename : src/dev/arm/versatile.hh => src/dev/arm/realview.hh
2010-08-20devices: Fixed periodic interrupts to work with drainingBrad Beckmann
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.
2010-08-17bus: clean up default responder code.Steve Reinhardt
Clean up some minor things left over from the default responder change in rev 9af6fb59752f. Mostly renaming the 'responder_set' param to 'use_default_range' to actually reflect what it does... old name wasn't that descriptive in the first place, but now it really doesn't make sense at all. Also got rid of the bogus obsolete assignment to 'bus.responder' which used to be a parameter but now is interpreted as an implicit child assignment, and which was giving me problems in the config restructuring to come. (A good argument for not allowing implicit child assignments, IMO, but that's water under the bridge, I'm afraid.) Also moved the Bus constructor to the .cc file since that's where it should have been all along.
2010-06-15stats: only consider a formula initialized if there is a formulaNathan Binkert
2010-06-03Act like enabling CPUs is no big deal,Steve Reinhardt
rather than a scary thing that might not work.
