Bahadir Balban 1e8c0f1d3a Added ipc tags for uart service. Set size field for kernel-managed devices 2009-11-22 23:41:19 +02:00
Bahadir Balban 877b2cedc7 Integrated libl4thread with libl4. Added device number to device caps. 
A 16-bit device number or id further distinguishes a device on the
system in addition to the device type. This is meant to be used for
the very first identification of the device for further probing. Any
further info is available by userspace mapping and probing.

Bahadir Balban 26d469fccd Corrected some license/copyright headers in uart code. 2009-11-22 15:19:23 +02:00
Bahadir Balban 2a36465100 Updated example cmls with new symbols 2009-11-22 15:13:18 +02:00
Bahadir Balban 19b4c6c4c1 Moved capability struct to api/capability.h for userspace coherence 
Userspace often breaks as we change the capability structure. Now
structure is under api/ so userspace can also update with changes.

Bahadir Balban f3f581f2e7 Empty containers working as normal with device changes/cleanups 2009-11-22 14:42:49 +02:00
Bahadir Balban f1efee2475 Compiles with new changes but not still in progress 2009-11-22 00:17:58 +02:00
Bahadir Balban a3cfa2ac9b Added a device attribute to capabilities - In progress 
Followed the kernel physical memory reservation convention
with devices. Devices that are possessable by userspace
are created as boot-time capabilities and placed under the kernel
resources devmem_free capability list. Any userspace container
that is defined with the possession of the device would delete the
device capability making it unavailable to further requests.

Bahadir Balban d826de2eea Initial work to introduce device types and device capabilities 2009-11-21 15:00:42 +02:00
Bahadir Balban caa7ac0764 Put cinfo array into initdata section. Added more precision in bootmem 
cinfo array is now freed along with other init memory.
bootmem allocator memory is reduced to be completely used up.
free boot memory now prints the used free memory as well.
 2009-11-21 13:35:53 +02:00
Bahadir Balban 5bff5b5fbf Reduced maximum number of pagers to 1, and boot-time capabilities to 16 
Each container was taking up more than 3KB of space at boot-time structures
This was due to having 4 pagers and 32 boot-time capabilities for each. This
caused the boot-time kernel size to vary a lot with capabilities. The new
numbers are optimum.

Particularly we always have a single pager per container, even though the
array structures allow more. Single pager makes container-wide privileges
and management simpler.

Bahadir Balban a13120c073 Added proper checking of capability overlap for memcap_unmap 2009-11-21 12:01:41 +02:00

Bora Sahin 496fba81c8 A shared space multi-threaded example application presenting the use of the 
thread library. It also exemplifies how a new sample application can be added.
 2009-11-17 21:48:46 +02:00
Bora Sahin 9a8e1fa437 A few things needed in the destroy code paths of a thread are added. 
The first one is related to resource recycling. The parent which is waiting its
child to exit did not delete its ktcb. Now, it deletes.

The second one is related to self destroy. The added code wakes up all the
waiters before it exits.
 2009-11-17 21:20:09 +02:00
Bora Sahin b2a2340594 Clean dcache CP0 instruction is corrected. Possibly it was caused by a typo. 2009-11-17 20:44:42 +02:00
Bora Sahin 7387d336cc Thread waiting is fixed. 
In the former case, when a child was exiting there was a risk of being preempted while it
was also taken away from the runqueue. In this situatuion, it may not have had
the chance of waking up the parent in case if it waits for the child to exit.

This was also true for suspend & resume so they were patched also.

Bahadir Balban b933db1e36 Fixed target symbol parsing in pre-typed capabilities 
Also renamed CONT to CONTAINER on certain symbols
 2009-11-17 12:34:59 +02:00
Bora Sahin a5eede8fb9 The very same fix we applied to the thread library but for posix this time. 2009-11-17 12:05:56 +02:00
Bora Sahin 682c62f8bb A fix and a helper macro for the thread library. 
The fix solves the problem of giving the last slice from a pool.

The helper macro makes utcb space creation easy for the user because we have to
consider a few things like alignment and total allocated space.
