Hi Luis,
These 4 patches alter pr_debug() messages for more info, and less
log-spam.
* add "for $modname:" to banners
helpful for finding one of many
[ 40.885922] main:layout_sections: Core section allocation order for test_dynamic_debug:
~20 lines of output
[ 40.885967] main:move_module: Final section addresses for test_dynamic_debug:
~2 lines - .init.text/data
* add symbol name to "Absolute symbol: <value>"
val ~== 0 - less interesting than name
[ 40.886006] main:simplify_symbols: Absolute symbol: 0x00000000 test_dynamic_debug.c
[ 40.886008] main:simplify_symbols: Absolute symbol: 0x00000000 test_dynamic_debug.mod.c
* add size to section report. gives more info.
[ 40.885968] main:move_module: 0xffffffffc0249000 0x0000035d .text
[ 40.885971] main:move_module: 0xffffffffc0252000 0x0000003c .init.text
* drop already_uses: pr_debug("$ uses $b!") messages
echo module main +pmf >/proc/dynamic_debug/control
modprobe i915
before:
dmesg | grep already_uses | cut -c15- | wc
673 2722 28641
dmesg | grep already_uses | cut -c15- | sort -u | wc
26 134 1237
after:
dmesg | grep already_uses | cut -c15- | wc
15 90 756
dmesg | grep already_uses | cut -c15- | sort -u | wc
15 90 756
Jim Cromie (4):
module: in layout_sections, move_module: add the modname
module: add symbol-name to pr_debug Absolute symbol
module: add section-size to move_module pr_debug
module: already_uses() - reduce pr_debug output volume
