ecebc5ce - kdb: Get rid of broken attempt to print CCVERSION in kdb summary

Sat, 23 Mar 2019 01:52:27 +0000

kdb: Get rid of broken attempt to print CCVERSION in kdb summaryIf you drop into kdb and type "summary", it prints out a line thatsays this: ccversion CCVERSION...and I don't mean that it actually prints out the version of the Ccompiler. It literally prints out the string "CCVERSION".The version of the C Compiler is already printed at boot up and itdoesn't seem useful to replicate this in kdb. Let's just delete it.We can also delete the bit of the Makefile that called the C compilerin an attempt to pass this into kdb. This will remove one extra callto the C compiler at Makefile parse time and (very slightly) speed upbuilds.Signed-off-by: Douglas Anderson Reviewed-by: Masahiro Yamada Signed-off-by: Daniel Thompson List of files: /linux-6.15/kernel/debug/kdb/Makefile

ada64e4c - kgdboc,keyboard: Keyboard driver for kdb with kgdb

Fri, 21 May 2010 02:04:24 +0000

kgdboc,keyboard: Keyboard driver for kdb with kgdbThis patch adds in the kdb PS/2 keyboard driver. This was mostly adirect port from the original kdb where I cleaned up the code againstcheckpatch.pl and added the glue to stitch it into kgdb.This patch also enables early kdb debug via kgdbwait and the keyboard.All the access to configure kdb using either a serial console or thekeyboard is done via kgdboc.If you want to use only the keyboard and want to break in early youwould add to your kernel command arguments: kgdboc=kbd kgdbwaitIf you wanted serial and or the keyboard access you could use: kgdboc=kbd,ttyS0You can also configure kgdboc as a kernel module or at run time withthe sysfs where you can activate and deactivate kgdb.Turn it on: echo kbd,ttyS0 > /sys/module/kgdboc/parameters/kgdbocTurn it off: echo "" > /sys/module/kgdboc/parameters/kgdbocSigned-off-by: Jason Wessel Reviewed-by: Dmitry Torokhov List of files: /linux-6.15/kernel/debug/kdb/Makefile

5d5314d6 - kdb: core for kgdb back end (1 of 2)

Fri, 21 May 2010 02:04:20 +0000

kdb: core for kgdb back end (1 of 2)This patch contains only the kdb core. Because the change set waslarge, it was split. The next patch in the series includes theinstrumentation into the core kernel which are mainly helper functionsfor kdb.This work is directly derived from kdb v4.4 found at:ftp://oss.sgi.com/projects/kdb/download/v4.4/The kdb internals have been re-organized to make them mostly platformindependent and to connect everything to the debug core which is used bygdbstub (which has long been known as kgdb).The original version of kdb was 58,000 lines worth of changes tosupport x86. From that implementation only the kdb shell, and basiccommands for memory access, runcontrol, lsmod, and dmesg where carriedforward.This is a generic implementation which aims to cover all the currentarchitectures using the kgdb core: ppc, arm, x86, mips, sparc, sh andblackfin. More archictectures can be added by implementing thearchitecture specific kgdb functions.[mort@sgi.com: Compile fix with hugepages enabled][mort@sgi.com: Clean breakpoint code renaming kdba_ -> kdb_][mort@sgi.com: fix new line after printing registers][mort@sgi.com: Remove the concept of global vs. local breakpoints][mort@sgi.com: Rework kdb_si_swapinfo to use more generic name][mort@sgi.com: fix the information dump macros, remove 'arch' from the names][sfr@canb.auug.org.au: include fixup to include linux/slab.h]CC: linux-arch@vger.kernel.orgSigned-off-by: Jason Wessel Signed-off-by: Martin Hicks List of files: /linux-6.15/kernel/debug/kdb/Makefile
