To allow for more flexibility, this notifies domain shutdown through a function rather than a wake queue, to let the application use a wake queue only if it wishes.

I was also able to get the LDT switching functionality out of the critical path in switch_mm, which reduces the number of function calls, potential TLB misses and code size.

Hi, I am still new to R and this is my first post on this mailing-list. I have two .csv (each one being a column of real numbers) coming from the same database (the first one is just longer than the second) and I read them in R the following way: returns <- read.csv("test.csv", header = FALSE) returns2 <- read.csv("test2.csv", header = FALSE) However, the two

I recently started using Ogg Vorbis and decided I wanted high-quality files on my desktop, and small files on my Zaurus; but I didn't want to keep switching grip's configuration back and forth. So I wrote ogg2enc, a Perl script which takes the same command-line arguments as oggenc, and runs oggenc twice. The first run gets its command line munged to produce a file at 64kpbs; the second

By moving init_new_context and destroy_context inline into mmu_context.h, we can avoid extra functions calls, which are only needed for the unlikely case that the process context has an LDT to deal with. Now the code in ldt.c is called only when actually dealing with LDT creation or destruction. Careful analysis of alloc_ldt function showed that by using two const parameters, huge amounts of

Bump! I realize my previous message may have been a bit abrupt, without much proper explanations, though it is a serious application! Currently, the feedback of LLVM regarding the optimizations performed is an optional list of optimization names, through the detailed pass statistics. Though of high relevance to a user familiar with optimizing compilers, for unfamiliar users it might be

Big cleanup of LDT code. This code has very little type checking and is not frequently used, so I audited the code, added type checking and size optimizations to generate smaller assembly code. I changed the ldt count to be in pages, and converted the char * ldt into a desc_struct. Signed-off-by: Zachary Amsden <zach@vmware.com> Index: linux-2.6.14-zach-work/arch/i386/kernel/ldt.c

Hi Thibault, mclapply has been designed to signal an error in two ways. User code errors are returned as special objects (of class "try-error") in the respective element of the result list. All other errors (including a process killed) are returned as NULL in the respective elements of the result list. To detect these errors reliably, one needs to implement FUN so that it never

Last weekend I upgraded my server (complete reinstall, actually), from Debian sarge to wheezy, which brought me from dovecot 1.x (I think) to 2.1.7. It's all working now, *except* that the MUA I use on Android, Kaiten (a fork of K-9), apparently no longer gets IDLE notifications. Before the upgrade, when mail arrived, Kaiten would pop up an Android notification immediately; now, it

The stub domain device model needs to trap the termination signal so as to actually destroy the stub domain. SIGKILL can''t be trapped, SIGTERM is caught by SDL and so may be unnoticed. SIGHUP can be trapped and is not caught by SDL (and by default causes a process termination without core). Signed-off-by: Samuel Thibault <samuel.thibault@eu.citrix.com> diff -r 2407a61c0d30
