similar to: [PATCH] - Hotkey to break hypervisor out of tight loop

NOTE: An applicable subset of this patch was also submitted to upstream qemu. SUMMARY: This patch fixes several bugs in serial.c (1) A typo in serial_save() where qemu_get_8s is called (should be qemu_put_8s) (2) No support provided in serial_load() for version_id == 1 (should unmarshal a 1 byte s->divider and should provide a default value for s->fcr (3) Call serial_ioport_write() to

This is the xen part of the kthread patch This part simply fixes a compiler warning we get when compiling for a uniprocessor guest kernel.

The code, below, in rdmsr_hypervisor_regs (in xen/arch/x86/traps.c) looks wrong. (The same code is in wrmsr_hypervisor_regs.) int rdmsr_hypervisor_regs( uint32_t idx, uint32_t *eax, uint32_t *edx) { idx -= 0x40000000; if ( idx > 0 ) return 0; ... The intent, apparently, is that the function should return zero if the original idx exceeds 0x40000000. However because idx is

Hi, Robert, I found out another confusing code snippet: in void xi_invl_mfn(struct domain *d, unsigned long mfn) if (ext && pfn < ext->large_page_aligned_size) According to the code, it should be if (ext && (pfn>>SPT_ENTRIES_ORDER) < ext->large_page_aligned_size) If I made any mistake, please point it out.

Hello Han, I am pleased you approve of the design and implementation of the XI shadow mechanism. And I appreciate the time and care you''ve taken in reviewing this substantial body of new code. You asked about performance statistics. With the current XI patch, we are seeing the following: - page faults times for XI are about 4 times faster than non-XI: 10.56 (non-XI) vs 2.43

Hello, Stumble upon this issue. If one define digits as hotkeys, the action is also taken for the non-reserved CTRL-P to CTRL-Y (also affect ASCII prior to digits). Here's a quick patch, quickly tested for action on uppercase/lowercase and digit and inaction on "matching" CTRL key. Regards, Dany *Sample config section* LABEL extra2 MENU LABEL ^2.

Do you have any idea of the sort of timescale, and whether it'll be available as a patch that we can apply to our

Hi, What if some fail2ban magic could keep OpenSIPs response from hitting Asterisk after N attempts ?

How do I specify a "tight" y-axis, where the plot completely fills the y-axis range, inside the prepanel function? For example, consider the following code: require(lattice) set.seed(12345) x <- 1:1000 y <- cumsum(rnorm(length(x))) prepanel.test <- function(x, y, groups = NULL, subscripts = NULL, ...) { if (is.null(groups)) { result <- list(ylim = range(y)) }

3.71, using isolinux and simple menu system menu.c32 To avoid having many different menu config files (one for each submenu) I'm trying switching from the once required syntax ==== MENU LABEL > ^Firmware/BIOS KERNEL menu.c32 APPEND menufw.cfg ==== to ==== MENU BEGIN MENU TITLE ^Firmware/BIOS <stuff that was inside menufw.cfg> MENU END ==== However, it's not

Hi Folks Since updated to 1.0.1/2 I got a prob with the hotkey to access voicemailmain. According to the wiki "0" jumps to extension "o" and "*" to "a" "0" isn't working, I get vm-sorry followed by HangUp :( "*" is working and I get access. So I changed the dialplan to get my voicemail managed. Tested on zaphfc and capi Is

Hi, We're using Asterisk 13.17.0 with PJSIP 2.8 bundled. I've found an issue when Asterisk tries to make a SIP call out using auth, but has the wrong credentials and keeps getting returned a SIP 407, in this example to an OpenSIPs server requiring user auth. Basically this happens: 1. Asterisk sends plain INVITE to OpenSIPs 2. OpenSIPs responds with SIP 407 auth required with a

Hey, I want to change the default "shift" key to fall into the syslinux shell to something else but wasn't able to find the code where this is done. Can someone point me to this? thanks. Ram

Hello! I'm trying to install a Windows application called Macro Express, wich automatizes a lot of process with recorded macros. The macros are called by pressing Hotkeys combinations like Control+1 or Control+2 etc. Then, the macro sends keys to applications. I have installed the program on kubuntu and Wine 0.9.30. The problems are that it only regonizes Hotkeys when Macro Express window is

I was playing around in x86 assembly the other day, looking at ways to optimize my cooperative multitasking system. Currently, it uses a 'timeout' counter that is decremented each time through a loop, letting me stop the loop and go to the next cooperative thread if the loop runs a little long. The asm has two overlapping loops: --- _main: mov ecx, 1000000000 timeoutloop:
