I think vortex86sx has a tsc, so, you should try and modify the linux
kernel configuration to select CONFIG_X86_TSC, or simply select a
processor which has a tsc. You will get better latencies.
I've made two more tests:
- compiling for Pentium-Classic (M586-TSC)
=> Kernel doesn't boot at all
(I've seen invalid opcode, and after I-pipe stack call-trace
ftrace_make_nop)
- modifying arch/x86/Kconfig.cpu (there isn't any M486-TSC ! and X86-TSC
can't be acceded directly!?)
in config X86_TSC, adding for depends on M486
=> But also kernel not working.
I'm finally not sure if there is a TSC available in the Vortex86sx,
perhaps only on the Vortex86dx (fpu difference only normally),
or none !?
Someone on this list claimed that vortex86sx may have a tsc:
http://www.xenomai.org/pipermail/xenomai-help/2010-01/msg00153.html
I do not know for sure however.
Here with my previous 486 kernel, what gives /proc/cpuinfo:
processor : 0
vendor_id : CyrixInstead
cpu family : 4
model : 1
model name : Cx486SLC
stepping : unknown
fdiv_bug : yes
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : no
fpu_exception : no
cpuid level : -1
wp : yes
flags :
bogomips : 96.51
clflush size : 32
cache_alignment : 32
address sizes : 32 bits physical, 32 bits virtual
power management:
You would have "tsc" in the flags if that cpu had a tsc. So, I guess you
are right, this cpu does not have a tsc.
I've tested again with another card having this time a Vortex86DX on it.
Reused the same kernel sources, choosing "Pentium-classic" M586TSC and
no more activated "math emulation".
And surprise it works perfectly !
So for me, it's seems not to be really the same processor, and not only
a FPU add-on difference...
Even if when I asked ICOP, they tell me only performance & FPU
difference, strange.
Interesting, this time here what cat /proc/cpuinfo gives me :
processor : 0
vendor_id : Vortex86 SoC
cpu family : 5
model : 2
model name : 05/02
stepping : 2
cpu MHz : 799.974
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu tsc cx8
bogomips : 1599.94
clflush size : 32
cache_alignment : 32
address sizes : 32 bits physical, 32 bits virtual
power management:
For information, Xenomai has been configured like that :
./configure --disable-x86-sep CFLAGS="-march=i586
-fno-omit-frame-pointer" LDFLAGS="-march=i586"
(I was surprised that the -fno-omit-frame-pointer were again necessary!!!)
With latency -p 10000 with load, best = 19 micro-secs & worst = 63
micro-secs.
The price is quite less for the vsx version, and even if also less
efficient for real-time, for my application it should be yet enough (2-3
tasks at 5-10 milli-secs) !?
(With VSX version, worst latency gives 200 micro-secs... finally not so
much ?)
And lastly, dmesg for people that could be interested with:
