similar to: [PATCH] virtio/virtio_ring: do some comment fixes

Hi, I'm a new contributor. I'm considering the possibility of adopting a third-party JSON library instead of LLVM's homegrown `lib/Support/JSON.cpp`. The way I see it, this would bring several advantages as well as some downsides: + Slimmer codebase. + Benefit from upstream work and active contributions to another project. + Possibly improved performance and API ergonomics. -

I would like to do something like: exten => s,1,playback(http://my.server.com/file.wav) I tested and it does not work. It seems highly likely that someone would already have done this one way or another. I know I could do a system wget and then play the local file, but wanted something a bit more elegant. Thanks, Mike Clark

Hi there: Can someone help me with installing R on Unix? I tried the followings, but failed: (1) I downloaded http://cran.cnr.berkeley.edu/bin/linux/debian/stable/r-base_2.5.0.orig.tar.g z and unzipped the file. (2) I issued "./config" command, which ended up with a long log file. I attached below the last few lines. If anyone needs the full log, I can send it over. checking if libtool

exit_idle() should be called after irq_enter(), otherwise it throws: [ 2.513020] [ INFO: suspicious RCU usage. ] [ 2.513076] 3.6.5 #1 Not tainted [ 2.513128] ------------------------------- [ 2.513183] include/linux/rcupdate.h:725 rcu_read_lock() used illegally while idle!

Below should be useful for some experiments Jason is doing. I thought I'd send it out for early review/feedback. event idx feature allows us to defer interrupts until a specific # of descriptors were used. Sometimes it might be useful to get an interrupt after a specific descriptor, regardless. This adds a descriptor flag for this, and an API to create an urgent output descriptor. This is

Hello, all. I must be brain cramping badly on our Asterisk 1.6.1.1 installation. Our MeetMe macros are working fine except they do not prompt for a PIN. So I made a very simple conference room: exten => 7777,1,MeetMe(123456,cMaAsx,123456) Shouldn't this prompt the user who dials 7777 to enter a PIN before entering the conference room whether or not a PIN is defined in meetme.conf? I

Yes, Foxmail for mac client, after dovecot upgrade from 2.1.17 to new version, imap can't receive any email, I perform packet capture test, foxmail will not have next step after sending {LIST "" *} command action. Foxmail for mac client, dovecot version 2.1.17 can receive imap mail normally, because we need to add quota_max_mail_size configuration, we must upgrade to a higher

I finally found a reason TO run Asterisk as root. By default, ext[23] file systems "reserve" 5% of the filesystem for root. Thus, you may get some warning when everything non-root starts failing and give you a chance to free up some space before Asterisk is affected. -- Thanks in advance, ------------------------------------------------------------------------- Steve Edwards

This adds a way to check ring empty state after enable_cb outside any locks. Will be used by virtio_net. Note: there's room for more optimization: caller is likely to have a memory barrier already, which means we might be able to get rid of a barrier here. Deferring this optimization until we do some benchmarking. Signed-off-by: Michael S. Tsirkin <mst at redhat.com> ---

The 'disable_cb' callback is designed as an optimization to tell the host we don't need callbacks now. As it is not reliable, the debug check is overzealous: it can happen on two CPUs at the same time. Document this. Even if it were reliable, the virtio_net driver doesn't disable callbacks on transmit so the START_USE/END_USE debugging reentrance protection can be easily tripped

Hello Rusty, seems that we still have a problem with virtio_net and the enable_cb callback. During a long running network stress tests with virtio and got the following oops: ------------[ cut here ]------------ kernel BUG at drivers/virtio/virtio_ring.c:230! illegal operation: 0001 [#1] SMP Modules linked in: CPU: 0 Not tainted 2.6.26-rc2-kvm-00436-gc94c08b-dirty #34 Process netserver (pid:
