Gabe Black	51a3d65e25	X86: Finally fix a division corner case. When doing an unsigned 64 bit division with a divisor that has its most significant bit set, the division code would spill a bit off of the end of a uint64_t trying to shift the dividend into position. This change adds code that handles that case specially by purposefully letting it spill and then going ahead assuming there was a 65th one bit.	2010-05-02 00:39:29 -07:00
Nathan Binkert	e99828b06a	tick: rename Clock namespace to SimClock	2010-04-15 16:24:12 -07:00
Steve Reinhardt	4d77ea7a57	cpu: fix exec tracing memory corruption bug Accessing traceData (to call setAddress() and/or setData()) after initiating a timing translation was causing crashes, since a failed translation could delete the traceData object before returning. It turns out that there was never a need to access traceData after initiating the translation, as the traced data was always available earlier; this ordering was merely historical. Furthermore, traceData->setAddress() and traceData->setData() were being called both from the CPU model and the ISA definition, often redundantly. This patch standardizes all setAddress and setData calls for memory instructions to be in the CPU models and not in the ISA definition. It also moves those calls above the translation calls to eliminate the crashes.	2010-03-23 08:50:57 -07:00

Timothy M. Jones	29e8bcead5	O3PCU: Split loads and stores that cross cache line boundaries. When each load or store is sent to the LSQ, we check whether it will cross a cache line boundary and, if so, split it in two. This creates two TLB translations and two memory requests. Care has to be taken if the first packet of a split load is sent but the second blocks the cache. Similarly, for a store, if the first packet cannot be sent, we must store the second one somewhere to retry later. This modifies the LSQSenderState class to record both packets in a split load or store. Finally, a new const variable, HasUnalignedMemAcc, is added to each ISA to indicate whether unaligned memory accesses are allowed. This is used throughout the changed code so that compiler can optimise away code dealing with split requests for ISAs that don't need them.	2010-02-12 19:53:20 +00:00

Lisa Hsu	d6da172517	util: do checkpoint aggregation more cleanly, fix last changeset. 1) Move alpha-specific code out of page_table.cc:serialize(). 2) Begin serializing M5_pid and unserializing it, but adding an function to do optional paramIn so that old checkpoints don't need to be fixed up. 3) Fix up alpha startup code so that the unserialized M5_pid value is properly written to DTB_IPR_ASN. 4) Fix the memory unserialize that I forgot somehow in the last changeset. 5) Add in an agg_se.py to handle aggregated checkpoints. --bench foo-bar plus positional arguments foo bar are the only changes in usage from se.py. Note this aggregation stuff has only been tested for Alpha and nothing else, though it should take a very minimal amount of work to get it to work with another ISA.	2010-01-19 22:03:44 -08:00

Gabe Black	d3ed32b989	MIPS: Create an artificial control register to hold the thread pointer. In Linux, the set_thread_area system call stores the address of the thread local storage area into a field of the current thread_info structure. Later, to access that value, the program uses the rdhwr instruction to read a "hardware register" with index 29. The 64 bit MIPS manual, volume II, says that index 29 is reserved for a future ABI extension and should cause a "Reserved Instruction Exception". In Linux (and potentially other ISAs) that exception is trapped and emulated to return the value stored by set_thread_area as if that were actually stored by a physical register. The tp_value address (as named in the Linux kernel) is ironically stored as a control register so that it goes with a particular ThreadContext. Syscall emulation will use that to emulate storing to the OS's thread info structure, and rdhwr will emulate faulting and returning that value from software by returning the value itself, as if it was in hardware. In other words, we fake faking the register in SE mode. In an FS mode implementation it should work as specified in the manual.	2009-12-31 15:30:50 -05:00
Gabe Black	cc07dcf026	MIPS: Extract CPU pointer from the thread context in scheduleCP0 setMiscReg. The MIPS ISA object expects to be constructed with a CPU pointer it uses to look at other thread contexts and allow them to be manipulated with control registers. Unfortunately, that differs from all the other ISA classes and would complicate their implementation. This change makes the event constructor use a CPU pointer pulled out of the thread context passed to setMiscReg instead.	2009-12-31 15:30:50 -05:00

Vince Weaver	8f6744c19c	X86: add ULL to 1's being shifted in 64-bit values Some of the micro-ops weren't casting 1 to ULL before shifting, which can cause problems. On the perl makerand input this caused some values to be negative that shouldn't have been. The casts are done as ULL(1) instead of 1ULL to match others in the m5 code base.	2009-11-11 17:49:09 -05:00

Gabe Black	4779020e13	ARM: Fix the integer register indexes. The PC indexes in the various register sets was defined in the section for unaliased registers which was throwing off the indexing. This moves those where they belong. Also, to make detecting accesses to the PC easier and because it's in the same place in all modes, the intRegForceUser function now passes it through as index 15.	2009-11-10 20:19:55 -08:00
Vince Weaver	53e27c0277	X86: Fix bugs in movd implementation. Unfortunately my implementation of the movd instruction had two bugs. In one case, when moving a 32-bit value into an xmm register, the lower half of the xmm register was not zero extended. The other case is that xmm was used instead of xmmlm as the source for a register move. My test case didn't notice this at first as it moved xmm0 to eax, which both have the same register number.	2009-11-10 11:29:30 -05:00
Vince Weaver	e81cc233a6	X86: Remove double-cast in Cvtf2i micro-op This double cast led to rounding errors which caused some benchmarks to get the wrong values, most notably lucas which failed spectacularly due to CVTTSD2SI returning an off-by-one value. equake was also broken.	2009-11-10 11:18:23 -05:00

Gabe Black	bb903b6514	ARM: Simplify the load/store multiple generation code. Specifically, get rid of the big switch statement so more cases can be handled. Enumerating all the possible settings doesn't scale well. Also do some minor style clean up.	2009-11-08 15:16:59 -08:00
Nathan Binkert	708faa7677	compile: wrap 64bit numbers with ULL() so 32bit compiles work In the isa_parser, we need to check case statements.	2009-11-08 13:31:59 -08:00
Gabe Black	48525f581c	ARM: Split the condition codes out of the CPSR. This allows those bits to be renamed while allowing the other fields to control the behavior of the processor.	2009-11-08 02:08:40 -08:00

Gabe Black	3a3e846151	ARM: Get rid of NumInternalProcRegs. That constant is a carry over from Alpha and doesn't do anything in ARM.	2009-11-08 02:00:55 -08:00
Gabe Black	78bd8fe44f	ARM: Add back in spots for Rhi and Rlo, and use a named constant for LR.	2009-11-08 01:59:20 -08:00

Gabe Black	4a454c4f47	ARM: Set up an intregs.hh for ARM. Add constants for all the modes and registers, maps for aliasing, functions that use the maps and range check, and use a named constant instead of a magic number for the microcode register.	2009-11-08 00:07:35 -08:00

Vince Weaver	5cf2e7ccf0	X86: Fix problem with movhps instruction This problem is like the one fixed with movhpd a few weeks ago. A +8 displacement is used to access memory when there should be none. This fix is needed for the perlbmk spec2k benchmark to run.	2009-11-04 13:22:15 -05:00
Nathan Binkert	2c5fe6f95e	build: fix compile problems pointed out by gcc 4.4	2009-11-04 16:57:01 -08:00
Vince Weaver	a1042db290	X86: Enable x86_64 vsyscall support 64-bit vsyscall is different than 32-bit. There are only two syscalls, time and gettimeofday. On a real system, there is complicated code that implements these without entering the kernel. That would be complicated to implement in m5. Instead we just place code that calls the regular syscalls (this is how tools such as valgrind handle this case). This is needed for the perlbmk spec2k benchmark.	2009-11-04 00:47:12 -05:00
Vince Weaver	9b0a747dd4	X86: Hook up time syscall on X86 This has been tested and verified that it works.	2009-11-04 00:19:15 -05:00
Vince Weaver	a12557439b	X86: Add support for x86 psrldq and pslldq instructions These are complicated instructions and the micro-code might be suboptimal. This has been tested with some small sample programs (attached) The psrldq instruction is needed by various spec2k programs.	2009-10-30 12:49:37 -04:00
Vince Weaver	5873ec2238	X86: Implement movd_Vo_Edp on X86 This patch implements the movd_Vo_Edp series of instructions. It addresses various concerns by Gabe Black about which file the instruction belonged in, as well as supporting REX prefixed instructions properly. This instruction is needed for some of the spec2k benchmarks, most notably bzip2.	2009-10-30 15:52:33 -04:00
Vince Weaver	b2067840a6	X86: Implement the X86 sse2 haddpd instruction This patch implements the haddpd instruction. It fixes the problem in the previous version (pointed out by Gabe Black) where an incorrect result would happen if you issue the instruction with the same argument twice, i.e. "haddpd %xmm0,%xmm0" This instruction is used by many spec2k benchmarks.	2009-10-30 14:19:06 -04:00
Vince Weaver	cf269025f9	X86: Hookup truncate/ftruncate syscalls on X86 This patch hooks up the truncate, ftruncate, truncate64 and ftruncate64 system calls on 32-bit and 64-bit X86. These have been tested on both architectures. ftruncate/ftruncate64 is needed for the f90 spec2k benchmarks.	2009-10-30 12:51:13 -04:00
Gabe Black	3f722b991f	Syscalls: Make system calls access arguments like a stack, not an array. When accessing arguments for a syscall, the position of an argument depends on the policies of the ISA, how much space preceding arguments took up, and the "alignment" of the index for this particular argument into the number of possible storate locations. This change adjusts getSyscallArg to take its index parameter by reference instead of value and to adjust it to point to the possible location of the next argument on the stack, basically just after the current one. This way, the rules for the new argument can be applied locally without knowing about other arguments since those have already been taken into account implicitly. All system calls have also been changed to reflect the new interface. In a number of cases this made the implementation clearer since it encourages arguments to be collected in one place in order and then used as necessary later, as opposed to scattering them throughout the function or using them in place in long expressions. It also discourages using getSyscallArg over and over to retrieve the same value when a temporary would do the job.	2009-10-30 00:44:55 -07:00

Vince Weaver	14691148cd	Implement X86 sse2 movdqu and movdqa instructions The movdqa instruction should enforce 16-byte alignment. This implementation does not do that. These instructions are needed for most of x86_64 spec2k to run.	2009-10-21 13:40:43 -04:00

Vince Weaver	776f9405fa	Fix stat64 structure on 32-bit X86_SE The st_size entry was in the wrong place (see linux-2.6.29/arch/x86/include/asm/stat.h ) Also, the packed attribute is needed when compiling on a 64-bit machine, otherwise gcc adds extra padding that break the layout of the structure.	2009-10-20 15:15:37 -04:00
Timothy M. Jones	835a55e7f3	POWER: Add support for the Power ISA This adds support for the 32-bit, big endian Power ISA. This supports both integer and floating point instructions based on the Power ISA Book I v2.06.	2009-10-27 09:24:39 -07:00

Vince Weaver	56154cff5e	Enable getuid and getgid related syscalls on X86_SE I've tested these on x86 and they work as expected. In theory for 32-bit x86 we should have some sort of special handling for the legacy 16-bit uid/gid syscalls, but in practice modern toolchains don't use the 16-bit versions, and m5 sets the uid and gid values to be less than 16-bits anyway. This fix is needed for the perl spec2k benchmarks to run.	2009-10-19 17:29:34 -04:00
Vince Weaver	22dc2b5595	Ignore rt_sigaction() syscalls on x86 and x86_64 This is currently how alpha handles this syscall. This is needed for the gcc spec2k benchmarks to run.	2009-10-16 13:54:20 -04:00

Gabe Black	6e97feb8a5	X86: Make not taken conditional moves leave the destination alone. Adjust CMOVcc. The manuals from both AMD and Intel say that when writing to a 32 bit destination in 64 bit mode, the upper 32 bits of the register are filled with zeros. They also both say that the CMOV instructions leave their destination alone when their condition fails. Unfortunately, it seems that CMOV will zero extend its destination register whether or not it was supposed to actually do a move on both platforms. This seems to be the only case where this happens, but it would be hard to say for sure.	2009-08-08 17:23:19 -07:00

Gabe Black	3a55fc5cac	X86: Implement shift right/left double microops. This is my best guess as far as what these should do.

Korey Sewell	6211fe5d2e	inorder-float: Fix storage of FP results inorder was incorrectly storing FP values and confusing the integer/fp storage view of floating point operations. A big issue was knowing trying to infer when were doing single or double precision access because this lets you know the size of value to store (32-64 bits). This isnt exactly straightforward since alpha uses all 64-bit regs while mips/sparc uses a dual-reg view. by getting this value from the actual floating point register file, the model can figure out what it needs to store	2009-05-12 15:01:15 -04:00

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.	2009-04-26 02:09:13 -07:00
Gabe Black	c5e2cf841d	X86: Record the initial APIC ID which identifies an APIC in M5. The ID as exposed to software can be changed. Tracking those changes in M5 would be cumbersome, especially since there's no guarantee the IDs will remain unique.	2009-04-26 02:06:21 -07:00

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().

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

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
