| | | | | | | | | | | | | | | | | | | | | | | | | | When bootgraph.pl parses a file, it gives one row for each initcall's pid. But only few of them will be displayed => the longest.

| | | | | | | | | | | | | | | | | | | | David Sanders reported some issues with bootgraph.pl's display of his sytems bootup; this commit fixes these by scaling the graph not from 0 - end time but from the first initcall to the end time; the minimum display size etc also now need to scale with this, as does the axis display.

| * tracing/fastboot: add a script to visualize the kernel boot process / timeArjan van de Ven2008-10-141-0/+138
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When optimizing the kernel boot time, it's very valuable to visualize what is going on at which time. In addition, with the fastboot asynchronous initcall level, it's very valuable to see which initcall gets run where and when. This patch adds a script to turn a dmesg into a SVG graph (that can be shown with tools such as InkScape, Gimp or Firefox) and a small change to the initcall code to print the PID of the thread calling the initcall (so that the script can work out the parallelism).

| * ftrace: objcopy version test for local symbolsSteven Rostedt2008-10-141-0/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The --globalize-symbols option came out in objcopy version 2.17. If the kernel is being compiled on a system with a lower version of objcopy, then we can not use the globalize / localize trick to link to symbols pointing to local functions. This patch tests the version of objcopy and will only use the trick if the version is greater than or equal to 2.17. Otherwise, if an object has only local functions within a section, it will give a nice warning and recommend the user to upgrade their objcopy. Leaving the symbols unrecorded is not that big of a deal, since the mcount record method changes the actual mcount code to be a simple "ret" without recording registers or anything.

| * ftrace: handle weak symbol functionsSteven Rostedt2008-10-141-20/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During tests and checks, I've discovered that there were failures to convert mcount callers into nops. Looking deeper into these failures, code that was attempted to be changed was not an mcount caller. The current code only updates if the code being changed is what it expects, but I still investigate any time there is a failure. What was happening is that a weak symbol was being used as a reference for other mcount callers. That weak symbol was also referenced elsewhere so the offsets were using the strong symbol and not the function symbol that it was referenced from. This patch changes the setting up of the mcount_loc section to search for a global function that is not weak. It will pick a local over a weak but if only a weak is found in a section, a warning is printed and the mcount location is not recorded (just to be safe).

This will hold a list of pointers to the mcount relocation for each call site of mcount. For example: objdump -dr init/main.o [...] Disassembly of section .text: 0000000000000000 <do_one_initcall>: 0: 55 push %rbp [...] 000000000000017b <init_post>: 17b: 55 push %rbp 17c: 48 89 e5 mov %rsp,%rbp 17f: 53 push %rbx 180: 48 83 ec 08 sub $0x8,%rsp 184: e8 00 00 00 00 callq 189 <init_post+0xe> 185: R_X86_64_PC32 mcount+0xfffffffffffffffc [...] We will add a section to point to each function call. .section __mcount_loc,"a",@progbits [...] .quad .text + 0x185 [...] The offset to of the mcount call site in init_post is an offset from the start of the section, and not the start of the function init_post. The mcount relocation is at the call site 0x185 from the start of the .text section. .text + 0x185 == init_post + 0xa We need a way to add this __mcount_loc section in a way that we do not lose the relocations after final link. The .text section here will be attached to all other .text sections after final link and the offsets will be meaningless. We need to keep track of where these .text sections are. To do this, we use the start of the first function in the section. do_one_initcall. We can make a tmp.s file with this function as a reference to the start of the .text section. .section __mcount_loc,"a",@progbits [...] .quad do_one_initcall + 0x185 [...] Then we can compile the tmp.s into a tmp.o gcc -c tmp.s -o tmp.o And link it into back into main.o. ld -r main.o tmp.o -o tmp_main.o mv tmp_main.o main.o But we have a problem. What happens if the first function in a section is not exported, and is a static function. The linker will not let the tmp.o use it. This case exists in main.o as well. Disassembly of section .init.text: 0000000000000000 <set_reset_devices>: 0: 55 push %rbp 1: 48 89 e5 mov %rsp,%rbp 4: e8 00 00 00 00 callq 9 <set_reset_devices+0x9> 5: R_X86_64_PC32 mcount+0xfffffffffffffffc The first function in .init.text is a static function. 00000000000000a8 t __setup_set_reset_devices 000000000000105f t __setup_str_set_reset_devices 0000000000000000 t set_reset_devices The lowercase 't' means that set_reset_devices is local and is not exported. If we simply try to link the tmp.o with the set_reset_devices we end up with two symbols: one local and one global. .section __mcount_loc,"a",@progbits .quad set_reset_devices + 0x10 00000000000000a8 t __setup_set_reset_devices 000000000000105f t __setup_str_set_reset_devices 0000000000000000 t set_reset_devices U set_reset_devices We still have an undefined reference to set_reset_devices, and if we try to compile the kernel, we will end up with an undefined reference to set_reset_devices, or even worst, it could be exported someplace else, and then we will have a reference to the wrong location. To handle this case, we make an intermediate step using objcopy. We convert set_reset_devices into a global exported symbol before linking it with tmp.o and set it back afterwards. 00000000000000a8 t __setup_set_reset_devices 000000000000105f t __setup_str_set_reset_devices 0000000000000000 T set_reset_devices 00000000000000a8 t __setup_set_reset_devices 000000000000105f t __setup_str_set_reset_devices 0000000000000000 T set_reset_devices 00000000000000a8 t __setup_set_reset_devices 000000000000105f t __setup_str_set_reset_devices 0000000000000000 t set_reset_devices Now we have a section in main.o called __mcount_loc that we can place somewhere in the kernel using vmlinux.ld.S and access it to convert all these locations that call mcount into nops before starting SMP and thus, eliminating the need to do this with kstop_machine. Note, A well documented perl script (scripts/recordmcount.pl) is used to do all this in one location. Signed-off-by: Steven Rostedt <srostedt@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| * | | driver core: basic infrastructure for per-module dynamic debug messagesJason Baron2008-10-163-2/+75

I've introduced CONFIG_DYNAMIC_PRINTK_DEBUG, which when enabled centralizes control of debugging statements on a per-module basis in one /proc file, currently, <debugfs>/dynamic_printk/modules. When, CONFIG_DYNAMIC_PRINTK_DEBUG, is not set, debugging statements can still be enabled as before, often by defining 'DEBUG' for the proper compilation unit. Thus, this patch set has no affect when CONFIG_DYNAMIC_PRINTK_DEBUG is not set. The infrastructure currently ties into all pr_debug() and dev_dbg() calls. That is, if CONFIG_DYNAMIC_PRINTK_DEBUG is set, all pr_debug() and dev_dbg() calls can be dynamically enabled/disabled on a per-module basis. Future plans include extending this functionality to subsystems, that define their own debug levels and flags. Usage: Dynamic debugging is controlled by the debugfs file, <debugfs>/dynamic_printk/modules. This file contains a list of the modules that can be enabled. The format of the file is as follows: <module_name> <enabled=0/1> . . . <module_name> : Name of the module in which the debug call resides <enabled=0/1> : whether the messages are enabled or not For example: snd_hda_intel enabled=0 fixup enabled=1 driver enabled=0 Enable a module: $echo "set enabled=1 <module_name>" > dynamic_printk/modules Disable a module: $echo "set enabled=0 <module_name>" > dynamic_printk/modules Enable all modules: $echo "set enabled=1 all" > dynamic_printk/modules Disable all modules: $echo "set enabled=0 all" > dynamic_printk/modules Finally, passing "dynamic_printk" at the command line enables debugging for all modules. This mode can be turned off via the above disable command.
