Hi List, What this means? md: syncing RAID array md0 md: minimum _guaranteed_ reconstruction speed: 1000 KB/sec/disc. md: using maximum available idle IO bandwidth (but not more than 200000 KB/sec) for reconstruction. md: using 128k window, over a total of 2096384 blocks. md: md0: sync done.

I can't make it to the current schedule for alternate Tuesday 1400 UTC meetings. I was hoping we could reschedule it to 1500 UTC on the same Tuesdays instead, or any other slot which could work for all. What do other members think? -- Lokesh Freenode: lsm5 GPG: 0xC7C3A0DD -------------- next part -------------- A non-text attachment was scrubbed... Name: signature.asc Type:

Hi everyone, I'm in the formative stage of my PhD studies. My current focus is on integrated approaches to instruction scheduling and register allocation. A colleague pointed me to Evan Cheng's talk at the August 2008 developer meeting [1], where he very briefly mentioned allowing the register allocator to reschedule instructions as a "crazy idea" for the future. I

Since commit 39e6c8208d7b ("net: solve a NAPI race") napi has been able to be rescheduled within napi_complete_done() even in non-busypoll case, but virtnet_poll() always enabled interrupts before complete, and when napi was rescheduled within napi_complete_done() it did not disable interrupts. This caused more interrupts when event idx is disabled. According to commit cbdadbbf0c79

From: Martin Peres <martin.peres at labri.fr> This should fix a deadlock that has been reported to us where fan_update() would hold the fan lock and try to grab the alarm_program_lock to reschedule an update. On an other CPU, the alarm_program_lock would have been taken before calling fan_update(), leading to a deadlock. Reported-by: Marcin Slusarz <marcin.slusarz at gmail.com>

We don't have a rescheduling allocator, but we do have a post allocation rescheduler. Check out PostRASchedulerList.cpp It would still be interesting to be able to change scheduling during allocation, I think. /jakob

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 for

Adding Tejun to this thread per-Daniel's suggestion on IRC. Hi Tejun! So, I don't know what your experience with modesetting related stuff is so I'll quickly explain some important concepts here regarding scanlines, vblanks, etc. If you already understand this, feel free to skip this next paragraph. >From the perspective of a computer, every time a computer monitor displays a new

Hi, we are in the midst of an interesting work that begun with setting 'guessInstructionProperties = 0' in the SystemZ backend. We have found this to be useful, and discovered many instructions where the hasSideEffects flag was incorrectly set while it actually shouldn't. The attached patch and test case triggers an assert in TwoAddress.  (bin/llc ./tc_TwoAddr_crash.ll

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