wiz | cpuctl: be more verbose about problems and diagnosing them
|
| 1.33 |
| 06-Mar-2023 |
kre | Unless -v is given, ignore EEXIST errors from the IOC_CPU_UCODE_APPLY ioctl()
used to implement "cpuctl ucode N", which indicates that the microcode
to be loaded already exists in the CPU, and as such, isn't really a
very interesting "error".
|

mrg | branches: 1.32.2;
allow "cpuN" as well as "N" to specific a CPU.
update usage to include a change i made from 2015 to allow multiple
CPUs to be operated on at the same time for most commands.

| 21-Apr-2020 |
msaitoh | Get TSC frequency from CPUID 0x15 and/or x16 for newer Intel processors.
- If the max CPUID leaf is >= 0x15, take TSC value from CPUID. Some processors
can take TSC/core crystal clock ratio but core crystal clock frequency
can't be taken. Intel SDM give us the values for some processors.
- It also required to change lapic_per_second to make LAPIC timer correctly.
- Add new file x86/x86/identcpu_subr.c to share common subroutines between
kernel and userland. Some code in x86/x86/identcpu.c and cpuctl/arch/i386.c
will be moved to this file in future.
- Add comment to clarify.

mrg | branches: 1.29.4;
implement cpuctl identify for sparc and sparc64.
sparc:
- move enum vactype and struct cacheinfo into cpu.h
- move the cache flags from cpuinfo.flags into CACHEINFO.c_flags
(this allows the new cache_printf_backend() to see them.)
remove unused CPUFLG_CACHEIOMMUTABLES and CPUFLG_CACHEDVMA.
- align xmpsg to 64 bytes
- move cache_print() into cache_print.h so it can be shared with
cpuctl. it only depends upon a working printf().
- if found, store the CPU node's "name" into cpu_longname. this
changes the default output to show the local CPU not the
generic CPU family. eg:
cpu0 at mainbus0: mid 8: Ross,RT625 @ 90 MHz, on-chip FPU
vs the generic "RT620/625" previously shown.
- for each CPU export these things:
- name
- fpuname
- mid
- cloc
- freq
- psr impl and version
- mmu impl, version, and number of contexts
- cacheinfo structure (which changed for the first time ever
with this commit.)
sparc64:
- add a minimal "cacheinfo" structure to export the i/d/e-cache
size and linesize.
- store %ver, cpu node "name" and cacheinfo in cpu_info.
- set cpu_info ver, name and cacheinfo in cpu_attach(), and
export them via sysctl, as well as CPU ID and clock freq
cpuctl:
- add identifycpu_bind() that returns false on !x86 as their
identify routines do not need to run on a particular CPU to
obtain its information, and use it to avoid trying to set
affinity when not needed.
- add sparc and sparc64 cpu identify support using the newly
exported values.

mrg | branches: 1.28.8;
allow most commands to specify more than one cpu. now you can online or
offline (or identify, or intr/nointr) a list of cpus all together.
|

msaitoh | Fix a bug that an unknown command is printed as "(null)".
Reported by Fredrik Pettai.
|

msaitoh | Fix manual and usage bug. The ucode command can take [cpuno] argument.
|
| 1.23 |
| 23-Dec-2013 |
msaitoh | branches: 1.23.4;
Add verbose flag.
On x86 cpu, cpuctl -v identify dumps the return values of the cpuid
functions. The max levels are taken from CPUID 0 and CPUID 8000_0000.
It's useful for the future CPU.

(we always have more than 0).

drochner | branches: 1.21.2;
Extend the CPU microcode update framework to support Intel x86 CPUs.
Contrary to the AMD implementation, it doesn't use xcalls to distribute
the update to all CPUs but relies on cpuctl(8) to bind itself to the
right CPU -- to keep it simple and avoid possible problems with
hyperthreading.
Also, it doesn't parse the vendor supplied file to pick the right
part for the present CPU model but relies on userland to prepare
files with specific filenames. I'll commit a pkg for this in a minute
(pkgsrc/sysutils/intel-microcode).
The ioctl interface changed; compatibility is provided (should be
limited to COMPAT_NETBSD6 as soon as this is available).

for x86 and Xen Dom0.

ad | cpuctl:
- Add interrupt shielding (direct hardware interrupts away from the
specified CPUs). Not documented just yet but will be soon.
- Redo /dev/cpu time_t compat so no kernel changes are needed.
x86:
- Make intr_establish, intr_disestablish safe to use when !cold.
- Distribute hardware interrupts among the CPUs, instead of directing
everything to the boot CPU.
- Add MD code for interrupt sheilding. This works in most cases but there is
a bug where delivery is not accepted by an LAPIC after redistribution. It
also needs re-balancing to make things fair after interrupts are turned
back on for a CPU.

PR port-amd64/37461 x86 cpu dmesg output is noisy
Port identifycpu() to userspace. The kernel lies and reports on cpuN while
actually using the values from cpu0, but this attempts to bind itself to the
requested CPU if running as root. That doesn't work properly yet due to
kern/38588, but will do once that's fixed.

usr.sbin/cpuctl/arch/x86_64-asm.S: revisions 1.3-1.4
Update cpuctl(8). Microcode and ARM related changes are not included:
- Change the i386 asm x86_identify() so it returns a value instead of
writing into global data. Fix a stack alignment fubar that would
cause a crash on a cirix 486. Refactor identify code to common setup
for normal identify and ucode identify - which was missing a
memset().
- The Intel and AMD docs (more or less) agree on how the cpuid
'extended family' and 'extended model' bits are used to create
larger values than the original 16bit value allowed for.
Calculate and save these values 'up-front' and use them throughout.
Untangle the (backwards) nested switch statement for amd 'model 15'
cpus.
- Use full model number to index name strings - a lot of 256 element
arrays don't matter in usespace.
- Add support for the xsave related data from cpuid 8.n.
Reorder the output so that the 'brand' string - which actually
identifies the cpu is output first.
- Only complain about binding if we have more than 1 cpu.
- Check cpuid leaf 4 for newer Intel CPU to know the cache information.
- Support prefetch size.
- Print the highest extended info level as the basic info level.
- Update URL of AMD's web page.
- Add code to detect hypervisor. The code was based from FreeBSD and
ported by Kengo Nakahara.
- Add verbose flag.
- Add newline if ci_tsc_freq is 0 to not to break the output.
- Update Intel's processor family names and models.
- Print some more bits.
- Add shared TLB
- Add prototypes.
- Add comments.
- Make some functions static.
- Sort functions.
- KNF.

Fix bug, the computation of cpuset_nentries was incorrect, we must do +1
to be able to address the last 32 bits.
On a machine with 80 CPUs, this caused "cpuctl identify >64" to return
garbage.
