  • shared/irq_asm.S: From code inspection I have found the following issues (most SMP), and some improvements in irq_asm.S. I would need a long test with interrupts to verify the interrupt handler better, however I can not see that these patches hurt. Please see comment per hunk below, One should go through the file to indent delay-slots correctly, I have fixed some in the patch areas. An extra space is added in front of delay slots to indicate a delay slot.

158        * shared/bspstart.c, shared/start.S: Add capability for bootcard.c BSP
159        Initialization Framework to ask the BSP where it has memory for the
160        RTEMS Workspace and C Program Heap. These collectively are referred
161        to as work area. If the BSP supports this, then it does not have to
162        include code to split the available memory between the two areas.
163        This reduces the amount of code in the BSP specific bspstart.c file.
164        Additionally, the shared framework can initialize the C Library, call
165        rtems_debug_enable(), and dirty the work area memory. Until most/all
166        BSPs support this new capability, if the BSP supports this, it should
167        call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
168        When the transition is complete, this autoconf macro can be removed.

174        rtems_initialize_device_drivers, and
175        rtems_initialize_start_multitasking. This opened the sequence up so
176        that bootcard() could provide a more robust and flexible framework
177        which is easier to explain and understand. This also lays the
178        groundwork for sharing the division of available memory between the
179        RTEMS workspace and heap and the C library initialization across all
180        BSPs.

210        extra_mpci_receive_server_stack, stack_allocate_hook, and

307        be with or without DCache snooping. Caches without snooping needs the
308        drivers to flush cache or use the sparc instruction lda to force
309        cache miss...)

314
3152007-09-05      Daniel Hellstrom <daniel@gaisler.com>
316
317        * Makefile.am: LEON3 AMBA PnP bus scanning moved to shared/amba/amba.c
318        and shared/include/ambapp.h. The AMBA scanning was improved to take
319        account for PnP info address translation. This is useful when
320        scanning remote AMBA busses for example when a board connected with
321        PCI has an AMBA bus that needs to be scanned, before the addresses
322        was hard coded. Also, LEON2 now have AMBA PnP bus scanning support.
323        By using the new AMBA scanning routines it is possible to isolate the
324        AMBA scanning code to ambapp.c, however existing drivers should be
325        updated to use them in order to save space.

353        * shared/bspstart.c, shared/start.S: Use common clock driver template
354        and eliminate all fast idle code specific to this BSP. This
355        eliminates a fair amount of code in the BSP clock driver and
356        bsp_startup. The LEON3 has to do a scan of the AMBA bus to find the
357        timer so I added the new hook Clock_driver_support_find_timer to
358        support this. In general, there was some clean up to the file headers
359        of various files.
