Does SCM_RIGHTS limit on fd array apply to a particular cmsghdr or the whole ancillary data?

Hi, in the documentation on SCM_RIGHTS the maximum number of file descriptors that can be passed is described as (release 5.09 of the Linux man-pages project): | SCM_RIGHTS | Send or receive a set of open file descriptors from another | process. The data portion contains an integer array of

mmap vs. read/write performance/overhead revisited

Hi! So how is it _today_ with the current 4.x kernels when it comes to mmap vs read(2)/write(2)? Either it's my Google-foo lacking or the most recent comment on the topic really dates back 15 years, but this is the only substancial background information relevant for Linux I did find:

Typing "Linux XScale 270 or 27x" brings you a lot of pages but not an in depth doc/HOWTO how to compile your own kernel and make a boot image for that arch. The vendor from which I get the XScale sponsored has ready to use Linux images and source on his webpage, but they're kinda old and

Only few are also avaliable for x86_64 (AMD64), even fewer for IA64 and for other architectures it's getting homeopathic. This is IMHO a extreme distortion of the free market. Happy holydays Wolfgang Draxinger pgphFnTk0l3j7.pgp Description: PGP signature

Re: Binary Drivers

Probably any customly written driver will be suboptimal in the first place, but OTOH there are so many skilled people around in the OSS scene, that such a driver would surely soon catch up, if not even surpass the propritary one. Happy holydays Wolfgang Draxinger -- "sooner or later
