From: Ville Syrj?l? <ville.syrjala at linux.intel.com> Add some kind of vblank workers. The interface is similar to regular delayed works, and also allows for re-scheduling. Whatever hardware programming we do in the work must be fast (must at least complete during the vblank, sometimes during the first few scanlines of vblank), so we'll fire up a per-crtc high priority thread...

Hi! I''m new in ruby/rails programming and i have a small problem. I have installed InstantRails 1.0 (for Ruby/Rails/Mysql/Apache envs) and I''m trying to make a small app working. I''m using auth_generator for making a login page/users admin pages... and I have a problem when trying to CHANGE the avatar for the user. I have the following error: MissingSourceFile

Add some kind of vblank workers. The interface is similar to regular delayed works, and is mostly based off kthread_work. It allows for scheduling delayed works that execute once a particular vblank sequence has passed. It also allows for accurate flushing of scheduled vblank works - in that flushing waits for both the vblank s...

...gured it'd be a good idea to add a set of helpers for performing realtime hardware programming that's synchronized to vblank intervals. In particular, this is aimed at hardware programming that would be a bit too awkward to try to pull off entirely in interrupt context. We call these vblank workers. We first tried doing this using plain old kthreads, as you can see in the patch below, since we could schedule them as realtime. Additionally, the plan was to use this in i915 combined with pm_qos to get rid of cstate latency when handling the original vblank interrupt. Note, our time constrain...

I had llvm 2.9 installed on ununtu. I tried to build clang but got following error. I have llvm 2.9 and clang is latest version ( I don't know, I got from svn). I am wondering is it because of version problem ? Does clang work with 2.9 llvm ? llvm[3]: Compiling ClangASTNodesEmitter.cpp for Debug build In file included from

...ntexts so that we can block until a vblank work's target vblank has passed, _and_ said work has executed once since. And finally, we also want to be able to finish flushing on a work early if it's been cancelled at any point (e.g. before or after it's actually been queued on the kthread_worker). So, let's make all of these things possible by exposing struct kthread_flush_work, and then splitting kthread_flush_work() into two functions: kthread_queue_flush_work(); which handles possibly queuing up the kthread_flush_work on the work's respective kthread_worker, and kthread_flush_...

At a number of sites we are using Windows 2000 Server SP4 (APPSERVER) as a Terminal Server and a PDC. All user areas are stored on a NetBSD 1.6.2 server with Samba 3.0.7 using security = domain and a named password server. We've joined the domain from the Samba box (domain DOMAINNAME). In general everything works fine, but when a number of clients log on at around the same time (say 25 users

I am running the following llvm-ld command to produce native code: llvm-ld -native -o code.exe code.bc -lm However, I am getting the following assertion failure in llc. The bytecode has been processed with opt, it passes opt bytecode verification. I'm not too familiar with backend code generation. Does anyone have any insight in to what the problem might be or how to go about
