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 threa...

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 in Account#info no such file to load -- GD |RAILS_ROOT: ./script/../config/..| Application Tr...

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...

...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 constrai...

We used to implement the work flushing through tracking queued seq, done seq, and the number of flushing. This patch simplify this by just implement work flushing through another kind of vhost work with completion. This will be used by lockless enqueuing patch.

Hi Tejun! Sorry to bother you, but have you had a chance to look at any of this yet?

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 ?

I saw WARN_ON(!list_empty(&dev->work_list)) trigger so our custom flush is not as airtight as need be. This patch switches to a simple atomic counter + srcu instead of the custom locked queue + flush implementation. This will slow down the setup ioctls, which should not matter - it's slow path anyway. We use the expedited flush...

Currently, it's only possible to flush on a kthread_work in contexts where it's possible to block. This can be kind of painful though when trying to implement new types of delayed work which use kthread_work, since it means we'd need to drop any spinlocks for new delayed work implementations before we can actually call kthread_flush_work(). In t...

...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 at once), a fair proportion do not map their home drive. Doing a "net use U: /home" at a later time generally, but not always, maps it. It happens occasionally with 2.2.8, but we are getting feedback that 3....
