2008-05-15[S390] s390dbf: Use const char * for dbf name.Cornelia Huck
We should use const char * for passing the name of the debug feature around since it will not be changed. Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2008-04-17[S390] Add debug_register_mode() function to debug feature APIMichael Holzheu
The new function supports setting of permissions for the debugfs files created by the debug feature. In addition to that, the function provides uid and gid as parameters for future use. Currently only root is allowed for uid and gid.

2005-09-05[PATCH] s390: debug feature changesMichael Holzheu
debug feature changes/bug fixes: - Use get_clock() function instead of private inline assembly. - Use 'struct timeval' instead of 'struct timespec' for call to tod_to_timeval(). Now the microsecond part of the timestamp is correct again. - Fix a locking problem: when creating a snapshot of the current content of the debug areas, lock the entire debug_info object.

2005-06-25[PATCH] s390: debug feature changesMichael Holzheu
This patch changes the memory allocation method for the s390 debug feature. Trace buffers had been allocated using the get_free_pages() function before. Therefore it was not possible to get big memory areas in a running system due to memory fragmentation. Now the trace buffers are subdivided into several subbuffers with pagesize. Therefore it is now possible to allocate more memory for the trace buffers and more trace records can be written. In addition to that, dynamic specification of the size of the trace buffers is implemented. It is now possible to change the size of a trace buffer using a new debugfs file instance. When writing a number into this file, the trace buffer size is changed to 'number * pagesize'. In the past all the traces could be obtained from userspace by accessing files in the "proc" filesystem. Now with debugfs we have a new filesystem which should be used for debugging purposes. This patch moves the debug feature from procfs to debugfs. Since the interface of debug_register() changed, all device drivers, which use the debug feature had to be adjusted.

2005-05-01[PATCH] s390: allow longer debug feature namesMichael Holzheu
The current limitation of 16 characters of the debug feature names turned out to be insufficient. Increase it to 64 characters. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

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!
