Previously, it was impossible to hand e.g. the master device port to
more than one bootstrap task. Fix this by creating the send right as
it is inserted into the target task.
* kern/bootstrap.c (bootstrap_create): Do not create the send rights
here...
(boot_script_insert_right): ... but here.

machine-dependent interfaces.

Previously, bootstrap_create would print the multiboot modules with
padding applied to the end of the line. As multiboot modules as used
by the Hurd span more than one line. This makes the list of modules
hard to read and it looks unclean, more like an accident.
Furthermore, it is not clear what the intend of this was, as the
padding is applied at the end of the line, with no further information
printed thereafter.
* kern/bootstrap.c (bootstrap_create): Remove variable maxlen and len,
update printfs.

Previously, the function mig_strncpy would always zero-terminate the
destination string. Make mig_strncpy behave like mig_strncpy and
strncpy in the glibc. Also fix the implementation of mig_strncpy to
return the length of the written string to align the implementation
with the declaration in include/mach/mig_support.h.
* kern/ipc_mig.c (mig_strncpy): Do not zero-terminate the destination
string. Return length of destination string.
|
|
* kern/slab.c (KMEM_MAP_SIZE): Decrease from 128MiB to 96MiB.
|
|
task_set_name sets the name of a task. This is a debugging aid. The
name will be used in error messages printed by the kernel.
* kern/task.c (task_set_name): New function.
* kern/task.h (task_set_name): New declaration.
|

The slab allocator relies on the fact that kmem_cache_error does not
return. Previously, kmem_error was using printf. Use panic instead.
Found using the Clang Static Analyzer.
* kern/slab.c (kmem_error): Use panic instead of printf.
|
|
* kern/slab.c (kmem_cache_error): Use kmem_warn instead of kmem_error
to print the cache name and its address.
|
|
* kern/task.c (task_create): Initialize name with the address of the task.
* kern/task.h (TASK_NAME_SIZE): New definition.
(struct task): Add field name.

GNU MIG recently gained support for emitting x_server_routine
declarations in the generated server header file. Using this
declaration, the x_server_routine functions can be inlined into the
ipc_kobject_server function.
* kern/ipc_kobject.c: Include the mig-generated server headers.
|
|
* kern/slab.h (struct kmem_cache): Align kmem_cache objects using
__cacheline_aligned.
|
|
* kern/slab.h (struct kmem_cache): Reorder the fields so that all hot
fields are within the first cache line.
|
|
* kern/slab.h (KMEM_CACHE_NAME_SIZE): Explain the significance of the
chosen length.
|
|
Previously, the size of struct kmem_cache was 136 bytes, just eight
bytes larger than 128 bytes, which is typically two cache lines on
today's CPUs.
By reducing the size of the name field which holds a human-readable
description by eight bytes to 24 bytes, the struct kmem_cache can be
made fit into two cache lines. This change should not affect the
usefulness of this field. For reference, the length of the largest
hard-coded name is 17.
* kern/slab.h (KMEM_CACHE_NAME_SIZE): Define to 24.
|
|
* kern/task.h (struct task): Reduce the size of struct task by
2 * sizeof boolean_t by using a bit field for the boolean flags.
