It might not be perfect considering you can\noutput ASCII that might move the cursor position, but it is a\nsubstantially better approximation for viewing dmesg and trace logs.\n\nThis also means that the vt screen needs to set the kdb COLUMNS\nvariable.\n\nCc: \u003cstable@vger.kernel.org\u003e\nSigned-off-by: Jason Wessel \u003cjason.wessel@windriver.com\u003e\n" }, { "commit": "d1871b38fccdc4b6575b0cabdea9e06bc70167eb", "tree": "b750732307696a074df2d71be6b034ba96557d8b", "parents": [ "24b8592ec021c433e73e6d8000e71f5c341fdde0" ], "author": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Sun Aug 26 21:43:12 2012 -0500" }, "committer": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Fri Oct 12 06:37:35 2012 -0500" }, "message": "kdb: Fix dmesg/bta scroll to quit with \u0027q\u0027\n\nIf you press \u0027q\u0027 the pager should exit instead of printing everything\nfrom dmesg which can really bog down a 9600 baud serial link.\n\nThe same is true for the bta command.\n\nSigned-off-by: Jason Wessel \u003cjason.wessel@windriver.com\u003e\n" }, { "commit": "f30fed10c440a25937e509860fa207399b26efe5", "tree": "7697f5e044f1a870d0ddd1e5953d494cb3d9643e", "parents": [ "a0d271cbfed1dd50278c6b06bead3d00ba0a88f9" ], "author": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Fri Oct 12 06:37:33 2012 -0500" }, "committer": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Fri Oct 12 06:37:33 2012 -0500" }, "message": "kgdb: Add module event hooks\n\nAllow gdb to auto load kernel modules when it is attached,\nwhich makes it trivially easy to debug module init functions\nor pre-set breakpoints in a kernel module that has not loaded yet.\n\nSigned-off-by: Jason Wessel \u003cjason.wessel@windriver.com\u003e\n" }, { "commit": "ad394f66fa57ae66014cb74f337e2820bac4c417", "tree": "a10670b8a9b695aec7fba79d2be2191bd405a12a", "parents": [ "5a14fead07bcf4e0acc877a8d9e1d1f40a441153" ], "author": { "name": "Anton Vorontsov", "email": "anton.vorontsov@linaro.org", "time": "Mon Sep 24 14:27:51 2012 -0700" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Wed Sep 26 13:42:25 2012 -0700" }, "message": "kdb: Implement disable_nmi command\n\nThis command disables NMI-entry.

It holds a number of\n low level bits with no/few dependencies that are commonly used (eg.\n memory barriers) and a number of bits with more dependencies that\n aren\u0027t used in many places (eg. switch_to()).\n\n These patches break asm/system.h up into the following core pieces:\n\n (1) asm/barrier.h\n\n Move memory barriers here. This already done for MIPS and Alpha.\n\n (2) asm/switch_to.h\n\n Move switch_to() and related stuff here.\n\n (3) asm/exec.h\n\n Move arch_align_stack() here.

The algorithm for entering the kernel debug core and\nresuming kernel execution was racy and had several known edge case\nproblems with attempting to debug something on a heavily loaded system\nusing breakpoints that are hit repeatedly and quickly.\n\nThe prior \"locking\" design entry worked as follows:\n\n * The atomic counter kgdb_active was used with atomic exchange in\n order to elect a master cpu out of all the cpus that may have\n taken a debug exception.\n * The master cpu increments all elements of passive_cpu_wait[].\n * The master cpu issues the round up cpus message.\n * Each \"slave cpu\" that enters the debug core increments its own\n element in cpu_in_kgdb[].\n * Each \"slave cpu\" spins on passive_cpu_wait[] until it becomes 0.\n * The master cpu debugs the system.\n\nThe new scheme removes the two arrays of atomic counters and replaces\nthem with 2 single counters. One counter is used to count the number\nof cpus waiting to become a master cpu (because one or more hit an\nexception). The second counter is use to indicate how many cpus have\nentered as slave cpus.\n\nThe new entry logic works as follows:\n\n * One or more cpus enters via kgdb_handle_exception() and increments\n the masters_in_kgdb. Each cpu attempts to get the spin lock called\n dbg_master_lock.\n * The master cpu sets kgdb_active to the current cpu.\n * The master cpu takes the spinlock dbg_slave_lock.\n * The master cpu asks to round up all the other cpus.\n * Each slave cpu that is not already in kgdb_handle_exception()\n will enter and increment slaves_in_kgdb. Each slave will now spin\n try_locking on dbg_slave_lock.\n * The master cpu waits for the sum of masters_in_kgdb and slaves_in_kgdb\n to be equal to the sum of the online cpus.\n * The master cpu debugs the system.\n\nIn the new design the kgdb_active can only be changed while holding\ndbg_master_lock. Stress testing has not turned up any further\nentry/exit races that existed in the prior locking design. The prior\nlocking design suffered from atomic variables not being truly atomic\n(in the capacity as used by kgdb) along with memory barrier races.\n\nSigned-off-by: Jason Wessel \u003cjason.wessel@windriver.com\u003e\nAcked-by: Dongdong Deng \u003cdongdong.deng@windriver.com\u003e\n" }, { "commit": "c1bb9a9c1911036549c5cdfb23f32d7d20ffdc5a", "tree": "8d86976df36697e54ae3582d6c30b7355a942647", "parents": [ "91b152aa85bbcf076e269565394c31964f940371" ], "author": { "name": "Dongdong Deng", "email": "dongdong.deng@windriver.com", "time": "Mon Sep 13 06:58:00 2010 -0500" }, "committer": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Fri Oct 22 15:34:12 2010 -0500" }, "message": "debug_core: disable hw_breakpoints on all cores in kgdb_cpu_enter()\n\nThe slave cpus do not have the hw breakpoints disabled upon entry to\nthe debug_core and as a result could cause unrecoverable recursive\nfaults on badly placed breakpoints, or get out of sync with the arch\nspecific hw breakpoint operations.\n\nThis patch addresses the problem by invoking kgdb_disable_hw_debug()\nearlier in kgdb_enter_cpu for each cpu that enters the debug core.\n\nThe hw breakpoint dis/enable flow should be:\n\nmaster_debug_cpu slave_debug_cpu\n \\ /\n kgdb_cpu_enter\n |\n kgdb_disable_hw_debug --\u003e uninstall pre-enabled hw_breakpoint\n |\n do add/rm dis/enable operates to hw_breakpoints on master_debug_cpu..\n |\n correct_hw_break --\u003e correct/install the enabled hw_breakpoint\n |\n leave_kgdb\n\nSigned-off-by: Dongdong Deng \u003cdongdong.deng@windriver.com\u003e\nSigned-off-by: Jason Wessel \u003cjason.wessel@windriver.com\u003e\n" }, { "commit": "91b152aa85bbcf076e269565394c31964f940371", "tree": "32b2a8684877a15b050ef21c8ddcd583b695538d", "parents": [ "75d14edee5689716b55afe467acfc13206a31f95" ], "author": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Mon Aug 23 09:20:14 2010 -0500" }, "committer": { "name": "Jason Wessel", "email": "jason.wessel@windriver.com", "time": "Fri Oct 22 15:34:12 2010 -0500" }, "message": "kdb,kgdb: fix sparse fixups\n\nFix the following sparse warnings:\n\nkdb_main.c:328:5: warning: symbol \u0027kdbgetu64arg\u0027 was not declared.
