Nathan Binkert	e141cb7441	flags: Change naming of functions to be clearer	2008-12-06 14:18:18 -08:00
Lisa Hsu	f1430941cf	This brings M5 closer to modernity - the kernel being advertised is newer so it won't die on binaries compiled with newer glibc's, and enables use of TLS-toolchain built binaries for ALPHA_SE by putting auxiliary vectors on the stack. There are some comments in the code to help. Finally, stats changes for ALPHA are from slight perturbations to the initial stack frame, all minimal diffs.	2008-12-05 12:09:29 -05:00
Lisa Hsu	e2c7618e50	This patch pulls out the auxiliary vector struct from individual ISA ... LiveProcesses to the base LiveProcess definition so anyone can use them.	2008-12-04 18:03:35 -05:00
Steve Reinhardt	4514f565e3	syscalls: fix latent brk/obreak bug. ... Bogus calls to ChunkGenerator with negative size were triggering a new assertion that was added there. Also did a little renaming and cleanup in the process.	2008-11-15 09:30:10 -08:00
Nathan Binkert	5711282f87	Fix a bunch of bugs I introduced when I changed the flags stuff for packets. ... I did some of the flags and assertions wrong. Thanks to Brad Beckmann for pointing this out. I should have run the opt regressions instead of the fast. I also screwed up some of the logical functions in the Flags class.	2008-11-14 04:55:30 -08:00
Nathan Binkert	eb5d9ba72b	pseudo inst: Add rpns (read processor nanoseconds) instruction. ... This instruction basically returns the number of nanoseconds that the CPU has been running.	2008-11-10 11:51:18 -08:00
Nathan Binkert	9c49bc7b00	mem: update stuff for changes to Packet and Request	2008-11-10 11:51:17 -08:00

Nathan Binkert	44839d6b71	Fix a few more places where the context stuff wasn't changed	2008-11-05 07:20:03 -08:00
Lisa Hsu	dd99ff23c6	get rid of all instances of readTid() and getThreadNum(). Unify and eliminate ... redundancies with threadId() as their replacement.	2008-11-04 11:35:42 -05:00
Lisa Hsu	d857faf073	Add in Context IDs to the simulator. From now on, cpuId is almost never used, ... 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.	2008-11-02 21:57:07 -05:00
Lisa Hsu	67fda02dda	Make it so that all thread contexts are registered with the System, even in ... SE. Process still keeps track of the tc's it owns, but registration occurs with the System, this eases the way for system-wide context Ids based on registration.	2008-11-02 21:57:06 -05:00
Lisa Hsu	c55a467a06	make BaseCPU the provider of _cpuId, and cpuId() instead of being scattered ... across the subclasses. generally make it so that member data is _cpuId and accessor functions are cpuId(). The ID val comes from the python (default -1 if none provided), and if it is -1, the index of cpuList will be given. this has passed util/regress quick and se.py -n4 and fs.py -n4 as well as standard switch.	2008-11-02 21:56:57 -05:00
Nathan Binkert	9836d81c2b	style: Use the correct m5 style for things relating to interrupts.	2008-10-21 07:12:53 -07:00
Ali Saidi	b760b99f4d	O3CPU: Undo Gabe's changes to remove hwrei and simpalcheck from O3 CPU. Removing hwrei causes ... the instruction after the hwrei to be fetched before the ITB/DTB_CM register is updated in a call pal call sys and thus the translation fails because the user is attempting to access a super page address. Minimally, it seems as though some sort of fetch stall or refetch after a hwrei is required. I think this works currently because the hwrei uses the exec context interface, and the o3 stalls when that occurs. Additionally, these changes don't update the LOCK register and probably break ll/sc. Both o3 changes were removed since a great deal of manual patching would be required to only remove the hwrei change.	2008-10-20 16:22:59 -04:00

Nathan Binkert	80d9be86e6	gcc: Add extra parens to quell warnings. ... 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.	2008-09-27 21:03:49 -07:00

Nathan Binkert	8ea5176b7f	arch: TheISA shouldn't really ever be used in the arch directory. ... We should always refer to the specific ISA in that arch directory.

Nathan Binkert	0b30c345f1	alpha: Get rid fo the namespace called EV5. ... We're never going to do an alpha platform other than the one we've got.	2008-09-27 21:03:45 -07:00

Ali Saidi	91d968783e	Return an UnimpFault for an ITB translation of an uncachable address. We don't support fetching from uncached addresses in Alpha and it means that a speculative fetch can clobber device registers.	2008-08-13 16:29:59 -04:00
Nathan Binkert	1b1a7e33e7	style	2008-08-11 14:47:49 -07:00
Nathan Binkert	ee62a0fec8	params: Convert the CPU objects to use the auto generated param structs. ... A whole bunch of stuff has been converted to use the new params stuff, but the CPU wasn't one of them. While we're at it, make some things a bit more stylish. Most of the work was done by Gabe, I just cleaned stuff up a bit more at the end.	2008-08-11 12:22:16 -07:00

Nathan Binkert	f9a597ddf3	m5ops: clean up the m5ops stuff. ... - insert warnings for deprecated m5ops - reserve opcodes for Ali's stuff - remove code for stuff that has been deprecated forever - simplify m5op_alpha	2008-07-11 08:52:50 -07:00
Ali Saidi	a4a7a09e96	Remove delVirtPort() and make getVirtPort() only return cached version.	2008-07-01 10:25:07 -04:00
Ali Saidi	c5fbbf376a	Change everything to use the cached virtPort rather than created their own each time. ... This appears to work, but I don't want to commit it until it gets tested a lot more. I haven't deleted the functionality in this patch that will come later, but one question is how to enforce encourage objects that call getVirtPort() to not cache the virtual port since if the CPU changes out from under them it will be worse than useless. Perhaps a null function like delVirtPort() is still useful in that case.	2008-07-01 10:24:19 -04:00

Gabe Black	ff7b89beee	The process of going from an instruction definition to an instruction to be returned by the decoder has been fleshed out more. The following steps describe how an instruction implementation becomes a StaticInst. ... 1. Microops are created. These are StaticInsts use templates to provide a basic form of polymorphism without having to make the microassembler smarter. 2. An instruction class is created which has a "templated" microcode program as it's docstring. The template parameters are refernced with ^ following by a number. 3. An instruction in the decoder references an instruction template using it's mnemonic. The parameters to it's format end up replacing the placeholders. These parameters describe a source for an operand which could be memory, a register, or an immediate. It it's a register, the register index is used. If it's memory, eventually a load/store will be pre/postpended to the instruction template and it's destination register will be used in place of the ^. If it's an immediate, the immediate is used. Some operand types, specifically those that come from the ModRM byte, need to be decoded further into memory vs. register versions. This is accomplished by making the decode_block text for these instructions another case statement based off ModRM. 4. Once all of the template parameters have been handled, the instruction goes throw the microcode assembler which resolves labels and creates a list of python op objects. If an operand is a register, it uses a % prefix, an immediate uses $, and a label uses @. If the operand is just letters, numbers, and underscores, it can appear immediately after the prefix. If it's not, it can be encolsed in non nested {}s. 5. If there is a single "op" object (which corresponds to a single microop) the decoder is set up to return it directly. If not, a macroop wrapper is created around it. In the future, I'm considering seperating the operand type specialization from the template substitution step. A problem this introduces is that either the template arguments need to be kept around for the specialization step, or they need to be re-extracted. Re-extraction might be the way to go so that the operand formats can be coded directly into the micro assembler template without having to pass them in as parameters. I don't know if that's actually useful, though. src/arch/x86/isa/decoder/one_byte_opcodes.isa: src/arch/x86/isa/microasm.isa: src/arch/x86/isa/microops/microops.isa: src/arch/x86/isa/operands.isa: src/arch/x86/isa/microops/base.isa: Implemented polymorphic microops and changed around the microcode assembler syntax. --HG-- extra : convert_revision : e341f7b8ea9350a31e586a3d33250137e5954f43	2007-04-04 23:35:20 +00:00

Nathan Binkert	1aef5c06a3	Rework the way SCons recurses into subdirectories, making it ... automatic. The point is that now a subdirectory can be added to the build process just by creating a SConscript file in it. The process has two passes. On the first pass, all subdirs of the root of the tree are searched for SConsopts files. These files contain any command line options that ought to be added for a particular subdirectory. On the second pass, all subdirs of the src directory are searched for SConscript files. These files describe how to build any given subdirectory. I have added a Source() function. Any file (relative to the directory in which the SConscript resides) passed to that function is added to the build. Clean up everything to take advantage of Source(). function is added to the list of files to be built. --HG-- extra : convert_revision : 103f6b490d2eb224436688c89cdc015211c4fd30	2007-03-10 23:00:54 -08:00
