Ali Saidi 23755eb434 ARM: Make GIC function that should only be called by GIC protected. 2011-08-19 15:08:08 -05:00
Ali Saidi 243223ae63 IDE: Fix issues with new PIIX kernel driver and our model. 
The driver can read the IDE config register as a 32 bit register since
some adapters use bit 18 as a disable channel bit. If the size isn't
set in a PRD it should be 64K according to the SPEC (and driver) not
128K.

Geoffrey Blake f778c46b5e ARM: Add per-cpu local timers for ARM. 
Cortex-A9 processors can have a local timer and watchdog counter. It
is enabled by default in Linux and up to this point we've had to disable
them since a model wasn't available. This change allows a default
MP ARM Linux configuration to boot.

Steve Reinhardt 19bb896bfe config: revamp x86 config to avoid appending to SimObjectVectors 
A significant contributor to the need for adoptOrphanParams()
is the practice of appending to SimObjectVectors which have
already been assigned as children.  This practice sidesteps the
assignment operation for those appended SimObjects, which is
where parent/child relationships are typically established.

This patch reworks the config scripts that use append() on
SimObjectVectors, which all happen to be in the x86 system
configuration.  At some point in the future, I hope to make
SimObjectVectors immutable (by deriving from tuple rather than
list), at which time this patch will be necessary for correct
operation.  For now, it just avoids some of the warning
messages that get printed in adoptOrphanParams().

Nathan Binkert eddac53ff6 trace: reimplement the DTRACE function so it doesn't use a vector

Ali Saidi a432d8e085 Mem: Fix issue with dirty block being lost when entire block transferred to 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.

Joel Hestness d9f0a8288e MessagePort: implement the virtual recvTiming function to avoid double pkt 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.

Steve Reinhardt 6f1187943c Replace curTick global variable with accessor functions.

per-thread curTick values.

Steve Reinhardt c69d48f007 Make commenting on close namespace brackets consistent. 
Ran all the source files through 'perl -pi' with this script:

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.

Gabe Black 9268f895d5 UART: Make the 8250's MCR return a deterministic value. 
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.

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.

Steve Reinhardt 0685ae7a2d bus: clean up default responder code. 
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.

Gabe Black 06b3e3c303 X86: Implement lowest priority interrupts more correctly. 
Lowest priority interrupts are now delivered based on a rotating offset into
the list of potential recipients. There could be parasitic cases were a
processor gets picked on and ends up at that rotating offset all the time, but
it's much more likely that the group will stay consistent and the pain will be
distributed evenly.

Gabe Black 88ab4bb257 X86: Make the local APICs register themselves with the IO APIC. 
This is a hack so that the IO APIC can figure out information about the local
APICs. The local APICs still have no way to find out about each other.
Ideally, when the local APICs update state that's relevant to somebody else,
they'd send an update to everyone. Without being able to do a broadcast, that
would still require knowing who else there is to notify. Other broadcasts are
implemented using assumptions that may not always be true.

Steve Reinhardt 6629d9b2bc mem: use single BadAddr responder per system. 
Previously there was one per bus, which caused some coherence problems
when more than one decided to respond.  Now there is just one on
the main memory bus.  The default bus responder on all other buses
is now the downstream cache's cpu_side port.  Caches no longer need
to do address range filtering; instead, we just have a simple flag
to prevent snoops from propagating to the I/O bus.

the primary identifier for a hardware context should be contextId().  The
concept of threads within a CPU remains, in the form of threadId() because
sometimes you need to know which context within a cpu to manipulate.

Even though we're not incorrect about operator precedence, let's add
some parens in some particularly confusing places to placate GCC 4.3
so that we don't have to turn the warning off.  Agreed that this is a
bit of a pain for those users who get the order of operations correct,
but it is likely to prevent bugs in certain cases.

Nathan Binkert 50ef39af82 sockets: Add a function to disable all listening sockets. 
When invoking several copies of m5 on the same machine at the same
time, there can be a race for TCP ports for the terminal connections
or remote gdb.  Expose a function to disable those ports, and have the
regression scripts disable them.  There are some SimObjects that have
no other function than to be used with ports (NativeTrace and
EtherTap), so they will panic if the ports are disabled.
