[QNX7] x86_64 missing support for "big pages" (2MB)
hi all
a simple call to getpagesizes() shows that qnx7 x86_64 kernel supports only 4 KB pages, while qnx6.5 x86 supports both
4KB and 2MB "big pages" with no need for special configuration/options into the mkifs buildfile.
Is there a reason for not supporting big pages in x86_64 qnx7? Is is possible to enable big pages via startup/procnto
configuration?
We tuned many memory allocations in order to exploit the bigpages performaces increase under qnx6, and we would like to
keep these optimizaions under qnx7 also.
thanks in advance!
Davide
