Future AMD SVM supports a new feature called flush by ASID. The idea is to allow CPU to flush TLBs associated with the ASID assigned to guest VM. So hypervisor doesn''t have to reassign a new ASID in order to flush guest''s VCPU. Please review it.

Hi, I get this error when trying to insmod the ipp2p kernel module: "insmod: error inserting ''ipt_ipp2p.ko'': -1 Invalid module format" in the kernel log: "ipt_ipp2p: disagrees about version of symbol struct_module" Kernel version 2.6.20.4 iptables version: 1.3.5 ipp2p version: 0.8.2 (latest) Anyone tried ipp2p with kernel 2.6.20? Best Regards Niclas

...om llvm.org, have assertions enabled. (I'm told Apple ships LLVM with assertions disabled, which is why I mention llvm.org here). What do people think of disabling assertions? The advantage of disabling assertions is that LLVM runs faster. I don't know how much faster. It also makes for fairer comparisons with gcc releases, which have all but the cheapest checks disabled. The disadvantage of disabling assertions is that we get less information in bug reports. An additional consideration here is clang: while LLVM itself is reasonably mature, that's not the case for clang. I don'...

Dear all, I have a wav file that when I try to encode with the FLAC Frontend, I get "ERROR: unsupported format type 3". When I open it with an audio editor I find it is 44100 / 32 bit. I requantized it to 16 bit using the default dither and then compressed it with FLAC to get a 61 Mbyte file (the original was about 347 Mbyte). Obviously, this altered somewhat the quality, although

hello, I like your point here .. it's difficult to make such a comparision, since yacast.fr choosed to stream like that. Why did they choose to stream like that? That's beyond me, since Radio France has a budjet of millions. The point of this comparision was to show why is Radio France doing and paying for something like this? Me, with cheap computers which were had no more value (well,

...float file had been normalized so that all sample values are between -1.0 and +1.0 then the exponent part of each floating point value (8 bits out of 32 bits) would have been identical resulting in a very significant opportunity for a data compressor like WinRAR to do it's work. A much better (fairer?) comparison would be to compare how WinRAR compresses a 24 bit PCM WAV file in comparison to FLAC.

Anyone know if Puppet works with or might work with Ruby 1.9?

...ld was set to 4503599628419072 (00001000 00001000h). This is present in any SMB messages featuring a "Allocation size" field. Using another linux+samba working setup and sniffing SMB messages again, the "Allocation size" field was set to 1048576 (00001000 00000000h). Which is a fairer value :-) After a few investigations on the warnings (warning: right, left shift count >= width of type) when compiling ntrans.c, trans2.c and a few other files in libsmb, it seems that they come from the macros like SOFF_T and alike defined in include.h when LARGE_SMB_OFF_T is defined - which...

Hi, while testing some APERF/MPERF semantics I discovered that this feature is enabled in Xen Dom0, but is not reliable. The Linux kernel''s scheduler uses this feature if it sees the CPUID bit, leading to costly RDMSR traps (a few 100,000s during a kernel compile) and bogus values due to VCPU migration during the measurement. The attached patch explicitly disables this CPU capability

I need to know how to do the following in puppet. Say I have three classes, (c1,c2,c3) that are not related. These classes could be considered "attributes" that may or may not apply to an individual host on my network. I need to know how to write a manifest, or series of manifests to allow me trigger a command (call it ''foo'') if all three classes are defined. I also

Hi All, I have been bashing my head against the wall with this template problem. I have tried numerous variations on this, but the gist of it is this: When I create a template of over 105 (or so) lines, I get various strange error messages. Those messages vary depending on very tiny changes with the template (such as adding a single text line or variable). Sometimes the errors look like this:

Hi all, The past few weeks I've been busy comparing lossless audio codecs to update the comparison.html page on the FLAC website (and because I wrote a comparison for Hydrogenaudio in the past) and its ready now. Because the patch is pretty large, I've placed it here: http://www.icer.nl/misc_stuff/update-comparison-and-fix-IE-news.patch.zip The reason to do this is because the

I have a 100Mb comma-separated file, and R takes several minutes to read it (via read.table()). This is R 1.9.0 on a linux box with a couple gigabytes of RAM. I am conjecturing that R is gc-ing, so maybe there is some command-line arg I can give it to convince it that I have a lot of space, or?! Thanks! Igor

I''m trying to have puppet install a bunch of ruby gems for me, but I''m running into problems with a few of them. This is on CentOS 4.4, ruby 1.8.5 (2006-08-25) [x86_64-linux] and the latest puppet from svn as of yesterday afternoon. I have: package { fastthread: ensure => "0.6.4.1", provider => gem, require =>

Hi all, Can anyone show me pointers on how to get this implemented on a Linux box with tc rules? I also want to know, just how efficient is this Algorithm. AFAIK, inbound traffic control can''t really be achieved without losing bandwidth. In some of the howtos'' I''ve read, one guy had to limit his downspeed to 1/2 his bandwidth to actually control it. And he was saying
