SVN rev 195197 on 2009-06-30 17:10:08Z by avg MFC 185295, 185341, 185343: cpu identification improvements Goal of this MFC is to minimize unnecessary code differences between head and the branch, and to improve/fix invariant TSC detection for a wide range of CPUs. 185295 by takawata: Honor AMDPM_TSC_INVARIANT for Intel CPUs (i386 only) 185341 by jkim: Introduce cpu_vendor_id... 185343 by jkim: Use newly introduced cpu_vendor_id... These revision are bundled together because all intermediate revisions have one or more of the following deficiencies: o AMDPM_TSC_INVARIANT bit (CPUID.0x80000007.EDX[8]) is not honored for Intel CPUs; o AMD-specific CPU model/revision checks are performed on Intel CPUs.

- Remove the old smp cpu topology specification with a new, more flexible tree structure that encodes the level of cache sharing and other properties. - Provide several convenience functions for creating one and two level cpu trees as well as a default flat topology. The system now always has some topology. - On i386 and amd64 create a seperate level in the hierarchy for HTT and multi-core cpus. This will allow the scheduler to intelligently load balance non-uniform cores. Presently we don't detect what level of the cache hierarchy is shared at each level in the topology. - Add a mechanism for testing common topologies that have more information than the MD code is able to provide via the kern.smp.topology tunable.

Add an interface for drivers to be notified of changes to CPU frequency. cpufreq_pre_change is called before the change, giving each driver a chance to revoke the change. cpufreq_post_change provides the results of the change (success or failure). cpufreq_levels_changed gives the unit number of the cpufreq device whose number of available levels has changed. Hook in all the drivers I could find that needed it. * TSC: update TSC frequency value. When the available levels change, take the highest possible level and notify the timecounter set_cputicker() of that freq. This gets rid of the "calcru: runtime went backwards" messages. * identcpu: updates the sysctl hw.clockrate value * Profiling: if profiling is active when the clock changes, let the user know the results may be inaccurate.

Clear bit 22 in MSR IA32_MISC_ENABLE, according to Intel document, when the bit 22 is set to 1, CPUID with EAX=0 returns a maximum value in EAX[7..0] of 3, when set to 0(default), CPUID with EAX=0 returns the number corresponding to the maximum standard function supported. On my machine, BIOS sets the bit to 1 to make it to be compatible with old OS, this causes dual-core Pentium-D (two physical cores) to be identified as hyperthreading (two logical cores) by function mp_topology().

Begin promoting the AMD-originated feature flags to first class flags, now that newer Intel cpu hardware implements them too. This includes things like the NX (pte no-execute) flag for execute protection. We'll need to reference this for implementing no-exec in pmap.c at some point. Some feature flags are duplicated in both the Intel-orignated bits and the AMD bits. Suppress the the duplicates correctly - the old code assumed they were a 1:1 mapping which is not correct. We can't just mask off the bits present in cpu_feature. Converge with amd64 where this originated from. Intel cpu's that implement any AMD features will report them in dmesg now. Approved by: re

netchild's mega-patch to isolate compiler dependencies into a central place. This moves the dependency on GCC's and other compiler's features into the central sys/cdefs.h file, while the individual source files can then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42. By now, GCC and ICC (the Intel compiler) have been actively tested on IA32 platforms by netchild. Extension to other compilers is supposed to be possible, of course.

These are changes to allow to use the Intel C/C++ compiler (lang/icc)
to build the kernel. It doesn't affect the operation if gcc.
Most of the changes are just adding __INTEL_COMPILER to #ifdef's, as
icc v8 may define __GNUC__ some parts may look strange but are
necessary.
Additional changes:
- in_cksum.[ch]:
* use a generic C version instead of the assembly version in the !gcc
case (ASM code breaks with the optimizations icc does)
-> no bad checksums with an icc compiled kernel
Help from: andre, grehan, das
Stolen from: alpha version via ppc version
The entire checksum code should IMHO be replaced with the DragonFly
version (because it isn't guaranteed future revisions of gcc will
include similar optimizations) as in:

- assym.h:
* avoid zero-length arrays (remove dependency on a gcc specific

This change changes the contents of the object file, but as it's
only used to generate some values for a header, and the generator
knows how to handle this, there's no impact in the gcc case.

Incarnations of this patch survive gcc compiles since a loooong time,
I use it on my desktop. An icc compiled kernel works since Nov. 2003
(exceptions: snd_* if used as modules), it survives a build of the
entire ports collection with icc.

Define ovbcopy() as a macro which expands to the equivalent bcopy() call, to take care of the KAME IPv6 code which needs ovbcopy() because NetBSD's bcopy() doesn't handle overlap like ours. Remove all implementations of ovbcopy(). Previously, bzero was a function pointer on i386, to save a jmp to bzero_vector. Get rid of this microoptimization as it only confuses things, adds machine-dependent code to an MD header, and doesn't really save all that much. This commit does not add my pagezero() / pagecopy() code.

- Use cpu_exthigh instead of executing cpuid again to retrieve it for the print_AMD_foo() functions. - Add a brand name table for the brand index provided on Intel CPU's in %ebx after cpuid 1. - For Intel CPUs, if we don't get a processor name from the extended cpuid then use the brand index in cpuid_cpuinfo to pick a name from the brand table and copy that name into cpu_brand. - Replace the duplicated code to use the extended cpuid to replace cpu_model with the processor name in the AMD and Transmeta sections of printcpuinfo() with generic code that replaces cpu_model with cpu_brand if cpu_brand is not an empty string. We also trim leading spaces from cpu_brand prior to doing this since at least some processor names (notably those of Intel CPUs) have leading spaces in the name. - Give print_AMD_features() its own private regs[] array since printcpuinfo() doesn't use the one it has anymore.

Stop doing runtime checking on i386 cpus for cpu class. The cpu is
slow enough as it is, without having to constantly check that it really
is an i386 still. It was possible to compile out the conditionals for
faster cpus by leaving out 'I386_CPU', but it was not possible to
unconditionally compile for the i386. You got the runtime checking whether
you wanted it or not. This makes I386_CPU mutually exclusive with the
other cpu types, and tidies things up a little in the process.

There may exist two kinds of IBM BlueLightning CPU. One is that 5/2 test does not change undefined flag like Cyrix CPUs. Another is that 5/2 test changes undefined flag like Intel CPUs. Latter one could not be detected and was recognized 486DX CPU. To solve this, finishidentcpu() calls identblue() when cpu_vendor is null string (that is, CPUID instruction is not supported) and cpu == CPU_486. Tests have been done on IBM BlueLightning CPUs, i486SX and i486DX.

This commit gives support for the Rise mP6 CPU. It has two changes: 1. Rise is recognized in identdcpu.c. 2. The TSC is not written to. A workaround for the CPU bug is being applied to clock.c (the bug being that the mP6 has TSC enabled in its CPUID-capabilities, but it only supports reading it. If we try to write to it (MSR 16), a GPF occurs.) The new behavior is that FreeBSD will _not_ zero the TSC. Instead, we do a bit of 64-bit arithmetic.

[Forgot to commit this in the batch a few days ago.] Fixed profiling of elf kernels. Made high resolution profiling compile for elf kernels (it is broken for all kernels due to lack of egcs support). Renaming of many assembler labels is avoided by declaring by declaring the labels that need to be visible to gprof as having type "function" and depending on the elf version of gprof being zealous about discarding the others. A few type declarations are still missing, mainly for SMP. PR: 9413 Submitted by: Assar Westerlund <assar@sics.se> (initial parts)

From the submitter: CPU_WT_ALLOC does not work correctly for K6-2s of model 8+ and probably K6-3s (when they appear on the market soon). In addition, print_AMD_info() incorrectly printfs write allocation's size. I've fixed them, so they now Do The Right Thing, and added a "NO_MEMORY_HOLE" option to easily allow 15-16mb range handling for us K6 and K6-2 users. Submitted by: Brian Feldman <green@unixhelp.org>

Missing parens caused cpu features not to be printed for cyrix >= M2/MX. Althought the comments say the datasheet doesn't list the device ID registers on the M2/MX, they seem to be there and quite alive. (It's interesting to note that the M2/MX calls itself a 686 class cpu but is missing a heck of a lot of features, including VME, PGE, PSE, etc)

Even though BIOS writer's guide recommends cpuid instruction of Cyrix 6x86MX CPU is enabled (BIOS should not disable it), some BIOS disables it via CCR4. In this case, cpu variable becomes CPU_486 and identblue() is called. Because Cyrix 6x86MX has MSR and doesn't have MSR1002, wrmsr instruction generates general protection fault.

Work around for the Intel Pentium F00F bug; this is Intel's recommended workaround. Note that this currently eats up two pages extra in the system; this could be alleviated by aligning idt correctly, and then only dealing with that (as opposed to the current method of allocated two pages and copying the IDT table to that, and then setting that to be the IDT table).

Use `M2' instead of `6x86 with MMX'. Cyrix seems to use `M2' officially.

Man the liferafts! Here comes the long awaited SMP -> -current merge! There are various options documented in i386/conf/LINT, there is more to come over the next few days. The kernel should run pretty much "as before" without the options to activate SMP mode. There are a handful of known "loose ends" that need to be fixed, but have been put off since the SMP kernel is in a moderately good condition at the moment. This commit is the result of the tinkering and testing over the last 14 months by many people. A special thanks to Steve Passe for implementing the APIC code!

Make the necessary changes so that an ELF kernel can be built. I have successfully built, booted, and run a number of different ELF kernel configurations, including GENERIC. LINT also builds and links cleanly, though I have not tried to boot it. The impact on developers is virtually nil, except for two things. All linker sets that might possibly be present in the kernel must be listed in "sys/i386/i386/setdefs.h". And all C symbols that are also referenced from assembly language code must be listed in "sys/i386/include/asnames.h". It so happens that failure to do these things will have no impact on the a.out kernel. But it will break the build of the ELF kernel. The ELF bootloader works, but it is not ready to commit quite yet.

Improved CPU identification and initialization routines. This
supports All Cyrix CPUs, IBM Blue Lightning CPU and NexGen (now AMD)
Nx586 CPU, and initialize special registers of Cyrix CPU and msr of
IBM Blue Lightning CPU.
If revision of Cyrix 6x86 CPU < 2.7, CPU cache is enabled in
write-through mode. This can be disabled by kernel configuration
options.

Make the long-awaited change from $Id$ to $FreeBSD$ This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

Removed #include of "opt_temporary.h". All the temporary options went away, so this header is no longer generated. This change should be in 2.2. The old version shouldn;t have been in 2.2 (blush).

Replaced I586_OPTIMIZED_BCOPY and I586_OPTIMIZED_BZERO with boot-time negative-logic flags (flags 0x01 and 0x02 for npx0, defaulting to unset = on). This changes the default from off to on. The options have been in current for several months with no problems reported. Added a boot-time negative-logic flag for the old I5886_FAST_BCOPY option which went away too soon (flag 0x04 for npx0, defaulting to unset = on). Added a boot-time way to set the memory size (iosiz in config, iosize in userconfig for npx0). LINT: Removed old options. Documented npx0's flags and iosiz. options.i386: Removed old options. identcpu.c: Don't set the function pointers here. Setting them has to be delayed until after userconfig has had a chance to disable them and until after a good npx0 has been detected. machdep.c: Use npx0's iosize instead of MAXMEM if it is nonzero. support.s: Added vectors and glue code for copyin() and copyout(). Fixed ifdefs for i586_bzero(). Added ifdefs for i586_bcopy(). npx.c: Set the function pointers here. Clear hw_float when an npx exists but is too broken to use. Restored style from a year or three ago in npxattach().

Enable the i586-optimized bcopy if the cpu is a "586" and option I586_OPTIMIZED_BCOPY is configured. Similarly for bzero/I586_OPTIMIZED_BZERO. Fake 586's had better have a hardware FPU with non-broken exception handling (we mask exceptions, but broken exception handling may trap on the instructions that do the masking). I guess this means that the routines won't work on most 386's or FPUless 486's even when they have a h/w FPU.

Trivial cosmetic tweak to make the i[56]86 CPU MHz reprting round to the nearest .01 Mhz rather than simply truncating it downwards. This hack makes this 89.999928 Mhz clock correctly round to the closer 90.00-MHz rather than 89.99-MHz: > i586 clock: 89999928 Hz, i8254 clock: 1193152 Hz > CPU: Pentium (90.00-MHz 586-class CPU)

Fix something that's been bugging me for a long time: move the CPU type identification code out of machdep.c and into a new file of its own. Hopefully other grot can be moved out of machdep.c as well (by other people) into more descriptively-named files.
