Check the availablity of a recycle destination segment only when it is
necessary to avoid missing resycle source segment erasures.
|
|
Do not use the unavailable block count as the erased blocks starvation
threshold. Use instead the block count of the largest segment. This
improves the starvation resolution gain of available blocks.
|
|
Add the lipqos and sptest.
|
|
Since the CBS scheduler is inspired by AQuoSA project for Linux, additional API
(qreslib) compliant with Linux has been created.
Sptest for qreslib included.

Add new file for CBS documentation.
|
|
Adds documentation on the scheduler options and scheduler selection
to the User's Manual to reflect changes made in the development of
pluggable scheduling with EDF and CBS schedulers.

The new function rtems_bdbuf_set_block_size() must be used to set the
block size of a disk device. It will check if the block size is valid
and set the new fields block_to_media_block_shift and bds_per_group of
the rtems_disk_device structure. This helps to avoid complex arithmetic
operations in the block device buffer get and read path.
|
|
Calling the bdbuf API functions in the not configured state is now a
fatal error.
|
|
The transfer chain is accessed by at most one thread at a time.
|
|
The chains are protected by the bdbuf cache lock.

New macros
o _Objects_Maximum_per_allocation(),
o rtems_resource_is_unlimited(), and
o rtems_resource_maximum_per_allocation().
New function
o _Objects_Is_unlimited().

Add
o _Nios2_MPU_Get_region_descriptor(), and
o _Nios2_MPU_Set_region_registers().

In the Red-Black Tree Heap the administration data structures are not
contained in the managed memory area. This can be used for example in a
task stack allocator which protects the task stacks from access by other
tasks.

Fixed a bug where the vector number is used to clean and unmask
the IRQ at the IRQ controller, the irq number must be used.

Add and use function _ARMV7M_Set_exception_priority_and_handler(). Use
ARMV7M_EXCEPTION_PRIORITY_LOWEST define.

The ISR code is updated to use argument instead of global greth
structure, now that the greth private is available in the ISR.
The shared-irq routines will unmask the IRQ, so the forced LEON3
BSP unmask/clear IRQ is removed.

The implementation use IRQ number instead of vector number since
some IRQs does not have a unique vector, for example the extended
interrupts all enter the same trap vector entry.
Added support for the LEON3 extended interrupt controller when using
the shared IRQ layer.
ERC32 patches untested.

The UART indexing was rather a mess when MP was enabled. The changes
introduces two weak variables syscon_uart_index and debug_uart_index
so that the user can override the default system debug console (printk)
and system console UART (/dev/console).
The two weak variables is updated on boot to reflect the "real" UART
index.
MINOR DEVICE-FS-NAME UART
0 /dev/console Default /dev/console_a, user selectable
1 /dev/console_a APBUART[0] (missing by default)
2 /dev/console_b APBUART[1]
...
/dev/console_a is by default renamed /dev/console and assigned minor=0,
but user can select /dev/console_['a'+N] to be renamed to /dev/console
by setting syscon_uart_index=N.
On a MP system the console renamed to /dev/console is selected by CPU
index (LEON3_Cpu_Index). /dev/console_['a' + LEON3_Cpu_Index] is
renamed unless overrided. Resource sharing is performed by the user,
one should not open/access a console that another OS instance uses.
This patch also moves the initialization of the UART to the open()
call, note that before APBUART[0] was always enabled as debug uart
even on MP systems. The debug UART is initialized at boot time.

Add defines MPC55XX_HAS_SIU and MPC55XX_HAS_SIU_LITE.

o Move rtems_bsdnet_fdToSocket() and rtems_bsdnet_makeFdForSocket() to
"cpukit/libnetworking/rtems/rtems_syscall.c".
o The rtems_bsdnet_makeFdForSocket() function is now static.
o Check in rtems_bsdnet_fdToSocket() function that the file descriptor
uses the socket handlers, otherwise an error status will be returned
and errno set to ENOTSOCK.
o New test libtests/syscall01.

Change the ioctl_return type of rtems_libio_ioctl_args_t to match the
ioctl() return value type.

Do not use the e300 core decrementer auto-reload feature. We have to
use the normal decrementer handler since otherwise it is impossible to
pass test sptests/spnsext01.
