From: =?ISO-8859-1?Q?Nicolas_Castagn=E9?= To: linux-kernel@vger.kernel.org Content-Transfer-Encoding: 8BIT Message-Id: X-Mailer: Apple Mail (2.551) X-IMAG-MailScanner: Found to be clean X-IMAG-MailScanner-Information: Please contact the ISP for more information Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi all, I was very pleased that some patches for controlling CPU affinities were merged in the 2.5 (and 2.6) releases of the kernel. Where may I find precisions on the patches that are now included ? Especially, with the 2.6 release : - is it possible to control the cpu affinity of threads (as for processes) ? - is there also a patch to shield cpu against the scheduler ? - is there also a patch to shield cpu against all interruptions (especially hard clock interrups) ? We here are (very) used to SGI IRIX real time facilities, but also very new to linux. We plan on porting our hard-real-time applications for multisensorial simulation on linux. These questions are very important to us. Thx a lot in advance, and please believe I am VERY sorry if this is not the correct list for my questions, and if I disturbed serious work ;-). If so, please let me know !
