[Xenomai-core] [PATCH 1/2] Add support for sharing kernel/userland data between Xenomai and Linux

2009-12-23 Thread Wolfgang Mauerer
A new structure (struct xnshared) is introduced. It allows us to share generic data between user and kernel of Linux and Xenomai; a bitmap of feature flags located at the beginning of the structure identifies which data are shared. The structure is allocated in the global semaphore heap, and

[Xenomai-core] [PATCH 0/2] xnvdso mechanism and unit test

2009-12-23 Thread Wolfgang Mauerer
Hi, the following two mails integrate Gilles' comments into the xnvdso patch and add a unit test. Notice that this submission does not consider efficient access of shared data from kernel space. Since this problem is independent from the xnvdso mechanism, it will be addressed when I submit the

[Xenomai-core] [PATCH 2/2] Testcase for the xnvdso mechanism

2009-12-23 Thread Wolfgang Mauerer
This testcase checks if the value in xnvdso-features matches the value of XNVDSO_FEATURES, that is, if the information is correctly transferred from kernel to userland. Notice that the approach will fail once configurations are supported that know of multiple features and implement only some of
