2008-04-17kgdb: fix several kgdb regressionsJason Wessel2-1/+10
kgdb core fixes: - Check to see that mm->mmap_cache is not null before calling flush_cache_range(), else on arch=ARM it will cause a fatal fault. - Breakpoints should only be restored if they are in the BP_ACTIVE state. - Fix a typo in comments to "kgdb_register_io_module" x86 kgdb fixes: - Fix the x86 arch handler such that on a kill or detach that the appropriate cleanup on the single stepping flags gets run. - Add in the DIE_NMIWATCHDOG call for x86_64 - Touch the nmi watchdog before returning the system to normal operation after performing any kind of kgdb operation, else the possibility exists to trigger the watchdog.

2008-04-17kgdb: add x86 HW breakpointsJason Wessel2-0/+154
Add HW breakpoints into the arch specific portion of x86 kgdb. In the current x86 kernel.org kernels HW breakpoints are changed out in lazy fashion because there is no infrastructure around changing them when changing to a kernel task or entering the kernel mode via a system call. This lazy approach means that if a user process uses HW breakpoints the kgdb will loose out. This is an acceptable trade off because the developer debugging the kernel is assumed to know what is going on system wide and would be aware of this trade off. There is a minor bug fix to the kgdb core so as to correctly call the hw breakpoint functions with a valid value from the enum. There is also a minor change to the x86_64 startup code when using early HW breakpoints. When the debugger is connected, the cpu startup code must not zero out the HW breakpoint registers or you cannot hit the breakpoints you are interested in, in the first place.

2008-04-17kgdb: fix NMI hangsJason Wessel3-3/+19
This patch fixes the hang regression with kgdb when the NMI interrupt comes in while the master core is returning from an exception. Adjust the NMI logic such that KGDB will not stop NMI exceptions from occurring by in general returning NOTIFY_DONE. It is not possible to distinguish the debug NMI sync vs the normal NMI apic interrupt so kgdb needs to catch the unknown NMI if it the debugger was previously active on one of the cpus.

This fixes a problem where the > > "shutdown status flag" may remain set when a CPU is brought up after > > booting. > > btw., what problem does this result in, exactly? The shutdown status flag set to "0xA", corresponds to "JMP double word request without INT init". This JMP at reboot time is at an unintended location. And results in Triple faults in our case. Though this error at reboot can be safely ignored in a VM environment, am not sure what the effect would be on a physical system. May be it will result in a triple fault and an eventual hardware reset thus masking this BUG in the kernel. This fix just makes sure that we reset that status flag after initialization is done. Fix paranoia about using BIOS quickboot mechanism. Make sure that we clear the "shutdown status flag" in the CMOS register after each CPU is brought up. This fixes a problem where the "shutdown status flag" may remain set when a CPU is brought up after booting.

2008-04-17x86: remove superfluous initialisation in boot code.Alexander van Heukelum1-1/+1
In arch/x86/boot/compressed/misc.c, the variable vidmem is the only variable that ends up in de data segment. It's also superfluous, because the first thing the code does is: if (RM_SCREEN_INFO.orig_video_mode == 7) { vidmem = (char *) 0xb0000; vidport = 0x3b4; } else { vidmem = (char *) 0xb8000; vidport = 0x3d4; } This patch removes the initialisation.
