when multiport is off, virtio console invokes config access from irq context, config access is blocking on s390. Fix this up by scheduling work from config irq - similar to what we do for multiport configs. Signed-off-by: Michael S. Tsirkin <mst at redhat.com> --- Applies on top of "virtio_console: init work unconditionally" that I sent previously. drivers/char/virtio_console.c

Unfortunately there proved to be at least one bug which requires an ABI change, so we're best off not introducing multiport support until 2.6.35. While I generally left the multiport code paths intact, I really wanted to remove the ABI defines from the header, which meant some quite deep cuts.

when multiport is off, we don't initialize config work, but we then cancel uninitialized control_work on freeze. Signed-off-by: Michael S.

Dear compiler enthousiasts, the Epona[0] compiler team from Quarkslab is looking for a compiler enthusiast to work on LLVM bitcode obfuscation. The full job description is available here: https://quarkslab.com/#epona-engineer It's a job that requires creativity to design new code obfuscation, compiler skills to integrate them in our LLVM based compiler, tenacity to have everything run

Hi all, we have a problem with a reinvite sent by our SIP provider to change audio codec due to the recognition of a fax tone. After that the SIP call session has been established (INVITE and 200 OK) we have the following codec situation: UAC ASTERISK UAS | ASTERISK UAC PROVIDER g711 <----------------------> g711

Dear all I wrote a routine. At the end of each cycle of the loop I would like to save the result (plot) in a postcriptfile. Of course if I just use dev.print in the following way: dev.print(device=postcript, 'c:/Rfigures/plot_1.ps") I overwrite my results with the second cycle of the loop. I suppose there is a way to define the file name so that several plots are

Hi list, is there a way to achieve in asterisk (version 1.4.x) the behavior described below? * a caller place a call to an extension, and I want the caller hears the extension ringing for some seconds, and then hears the music on hold (or a courtesy message) _in the same call;_ * the called extension must continue to ring until answered. With the m(...) option in the Dial

Hi, Let's suppose we have an ELF executable that doesn't issue any syscall (I mean, syscalls are issued from an external dynamic library, not from the executable, and we can ignore such dynamic library because we have the proper equivalent library with the proper syscalls in MacOS and Windows). So, the question: Is it "currently possible" (by "currently possible" I
