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 !?
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

If could be interesting, here the kernel messages with my 486 + X86_TSC
kernel:
