* rootdir.c (rootdir_gc_slabinfo): Do not zero-terminate the generated
content.
|
|
Add a node 'slabinfo' to the root directory that contains information
about the slab allocator used in GNU Mach.
The formatting code has been taken from Richard Braun's standalone
client available here:
git://darnassus.sceen.net/rbraun/slabinfo.git
* rootdir.c (rootdir_gc_slabinfo): New function.
(rootdir_entries): Add node 'slabinfo'.
* Makefile (OBJS): Add mach_debugUser.o.
(rootdir.o): Add an explicit dependency on mach_debug_U.h.
Furthermore, add rules to create both functions.
|
|
The node structure for the `mounts' entry is created and destroyed on
each access, despite the fact a translator is activated on it. Fix the
issue by caching it.
* rootdir.c (rootdir_mounts_node): New variable.
(rootdir_mounts_node_lock): Likewise.
(rootdir_mounts_make_node): New function.
(rootdir_translator_make_node): Remove function.
(rootdir_entries): Replace `rootdir_translator_make_node' with
`rootdir_mounts_make_node'.
|
|
Make mounts a node with a passive translator record so that the mtab
translator is started on access if it is available.
* rootdir.c (MTAB_TRANSLATOR): New macro.
(rootdir_mounts_get_translator): New function.
(rootdir_mounts_exists): New function.
(rootdir_translator_make_node): Likewise.
(rootdir_entries): Add "mounts" node.
|
|
* rootdir.c (rootdir_fakeself_exists): Use the correct arguments for
this kind of function.
|
|
* rootdir.c (rootdir_gc_meminfo): Use unsigned long constant.
|
|
* rootdir.c: Include <mach/gnumach.h> and <mach/vm_cache_statistics.h>.
(rootdir_gc_meminfo): Call vm_cache_statistics and return the VM cache size.

This reverts commit d9fc76bd4e8c9a459fad7152135b738496318415, as it breaks
/proc/pid/stat

PSTAT_NO_MSGPORT flag.
|
|

opt_kernel_pid command-line option.

* rootdir.c (rootdir_gc_meminfo): Add swap information.
* TODO: Update.
|
|
* Makefile: Change FOOFLAGS defaults to appropriate values when
$(PROFILE) is defined.
* rootdir.c: Add an "exit" file, which causes exit to be called
when looked up, so that profiling data can be written to disk.
|
|
* process.c, rootdir.c: When converting timeval structures
into seconds or jiffies, make sure that floating point rounding errors
don't make the clock the result jump backwards on second boundaries.
|
|
* rootdir.c: Replace INIT_PID by KERNEL_PID, for boot time and
idle time purposes. (get_idletime): New function, queries the
kernel's idle thread. (rootdir_gc_uptime, rootdir_gc_stat): Use the
new function and provide the real idle time.
|
|
* procfs_dir.c, procfs_dir.h: Revamp the interface to make
the more complicated use cases somewhat less hackish.
* process.c: Update, specify a default make_node function.
* rootdir.c: Likewise; make this optional "self" link use case
somewhat less hackish.
|
|
* procfs.h: Make CONTENTS_LEN an ssize_t rather than a size_t,
and document the change.
* procfs.c (procfs_get_contents): Initialize CONTENTS_LEN to a
negative value, and fail with ENOMEM if it's still negative after the
callback returns. (everywhere): Update to ssize_t.
* dircat.c, netfs.c, process.c,
procfs_dir.c, proclist.c, rootdir.c: Update to
ssize_t and the new GET_CONTENTS semantics.
|
|

procfs_dir.c, proclist.c, rootdir.c: Update.
|
|
* proclist.c, proclist.h (proclist_create_node): Use a
ps_context passed by the caller; errors are no longer possible, rename
to proclist_make_node and change the signature accordingly.
* rootdir.c, rootdir.h (rootdir_create_node): Likewise.
* main.c (main): Create the ps_context here and pass it to
root_make_node. (root_make_node): Pass it to proclist_make_node and
rootdir_make_node.
|
|
* main.c (argp_parser, main): Add the --kernel-pid option.
* main.h: Publish it.
* rootdir.c (rootdir_gc_cmdline): New function.
|
|

* process.c (sc_tc): Use the user-provided clock frequency.
* rootdir.c (rootdir_gc_stat): Likewise.
|
|
* rootdir.c (rootdir_gc_uptime, rootdir_gc_stat): assume a
completely idle rather than completely busy system, so that the idle
seconds can be meaningfully divided by the idle jiffies by procps.
|
|
* rootdir.c: Add "meminfo", empty for now.
|
|
* rootdir.c: Add a fake "self" symlink which always points to
init.
