2013-08-27debugfs: provide debugfs_create_x64() when disabledJohannes Berg1-0/+7
commit 15b0beaa332b3923cc ("Add x64 support to debugfs") added debugfs_create_x64(), but forgot to provide it when debugfs is disabled, causing problems when code tries to use it even then. Provide the appropriate static inline. Cc: Huang Ying <[email protected]> Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2013-06-03debugfs: add get/set for atomic typesSeth Jennings1-0/+2
debugfs currently lack the ability to create attributes that set/get atomic_t values. This patch adds support for this through a new debugfs_create_atomic_t() function.

2011-11-18debugfs: add tools to printk 32-bit registersAlessandro Rubini1-0/+26
Some debugfs file I deal with are mostly blocks of registers, i.e. lines of the form "<name> = 0x<value>". Some files are only registers, some include registers blocks among other material. This patch introduces data structures and functions to deal with both cases. I expect more users of this over time.

2009-03-23debugfs: function to know if debugfs is initializedFrederic Weisbecker1-0/+8
Impact: add new debugfs API With ftrace, some tracers are registered in early initcalls and attempt to create files on the debugfs filesystem. Depending on when they are activated, they can try to create their file at any time. Some checks can be done on the tracing area but providing a helper to know if debugfs is registered make it really more easy.

Introduced by 8adb711f3668b034e7b956fac951ed08b53e0d55 ("debugfs: introduce stub for debugfs_create_size_t() when DEBUG_FS=n") and due to a simple missing "static inline".

2009-01-20debugfs: introduce stub for debugfs_create_size_t() when DEBUG_FS=nInaky Perez-Gonzalez1-0/+7
Toralf Förster <[email protected]> reported a build failure in the WiMAX stack when CONFIG_DEBUG_FS=n http://linuxwimax.org/pipermail/wimax/2009-January/000449.html This is due to debugfs_create_size_t() missing an stub that returns -ENODEV when the DEBUGFS subsystem is not configured in (like the rest of the debugfs API). This patch adds said stub. Reported-by: Toralf Förster <[email protected]> Signed-off-by: Inaky Perez-Gonzalez <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2009-01-07debugfs: add helpers for exporting a size_t simple valueInaky Perez-Gonzalez1-0/+2
In the same spirit as debugfs_create_*(), introduce helpers for exporting size_t values over debugfs. The only trick done is that the format verifier is kept at %llu instead of %zu; otherwise type warnings would pop up: format ‘%zu’ expects type ‘size_t’, but argument 2 has type ‘long long unsigned int’ There is no real way to fix this one--however, we can consider %llu and %zu to be compatible if we consider that we are using the same for validating in debugfs_create_{x,u}{8,16,32}().

2008-07-21debugfs: Implement debugfs_remove_recursive()Haavard Skinnemoen1-0/+4
debugfs_remove_recursive() will remove a dentry and all its children. Drivers can use this to zap their whole debugfs tree so that they don't need to keep track of every single debugfs dentry they created. It may fail to remove the whole tree in certain cases: sh-3.2# rmmod atmel-mci < /sys/kernel/debug/mmc0/ios/clock mmc0: card b368 removed atmel_mci atmel_mci.0: Lost dma0chan1, falling back to PIO sh-3.2# ls /sys/kernel/debug/mmc0/ ios But I'm not sure if that case can be handled in any sane manner.

2005-04-18[PATCH] debugfs: Reduce <linux/debugfs.h> dependenciesRoland Dreier1-0/+7
The current <linux/debugfs.h> include file is a little fragile in that it is not self-contained and hence may cause compile warnings or errors depending on the files included before it, the kernel config and the architecture. This patch makes things a little more robust by: - including <linux/types.h> to get definitions of u32, mode_t, and so on. - forward declaring struct file_operations. - including <linux/err.h> when CONFIG_DEBUG_FS is not set The last change is particularly useful, as a kernel developer is likely to build with debugfs always enabled and never see the build breakage cased if debugfs is disabled.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+92
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
