* 2008-07-16 Till Straumann <strauman@slac.stanford.edu>Till Straumann2008-07-162-2/+21
| | | | | * new-exceptions/cpu.c: use ppc_interrupt_get_disable_mask() to determine which bits to set/clear from _CPU_Context_Initialize().
* 2008-07-16 Till Straumann <strauman@slac.stanford.edu>Till Straumann2008-07-162-10/+35
| | | | | | | | | * new-exceptions/bspsupport/ppc_exc_asm_macros.h: Added a test to TEST_LOCK_crit so that a context switch is always prevented if MSR_CE is not set in the interrupt mask. (Support mode where the user wants to leave MSR_CE always enabled but abstains from calling OS primitives from the exception handler.)
* 2008-07-16 Till Straumann <strauman@slac.stanford.edu>Till Straumann2008-07-162-1/+13
| | | | | * shared/include/powerpc-utility.h: Added GET_INTERRUPT_MASK macro.

| | | | | | | * mpc6xx/mmu/pte121.c: use general "memory" clobber rather than memory input operand in inline assembly ("m" doesn't do what the manual says; see discussion on gcc mailing list around 2008/3/30)

| | | | | | | | | | * ChangeLog, mpc8xx/clock/clock.c, ppc403/clock/clock.c, ppc403/irq/ictrl.h, rtems/powerpc/powerpc.h: Removed all macro definitions which depended on the compiler defining a PPC CPU-model dependent symbol from files in cpukit. Macros which were not used by cpukit have been moved to libcpu/powerpc/rtems/powerpc/powerpc.h.

| | | | | | | | | | | | | | | | | | | | | | | | | * new-exceptions/bspsupport/ppc_exc_asm_macros.S, new-exceptions/bspsupport/ppc_exc_bspsupp.h, new-exceptions/bspsupport/ppc_exc_hdl.c, new-exceptions/bspsupport/vectors_init.c: fixed and enabled stack-switching algorithm which figures out if we already run on the ISR stack rather than relying on the _ISR_Nest_level. Added 'ppc_exc_crit_always_enabled' variable which defines the semantics of critical interrupts. Added a test to TEST_LOCK_crit so that calling ppc_exc_wrapup() (and possibly the dispatcher) is always skipped if the BSP/user wants to leave critical interrupts always enabled (at the expense of having no OS support). changed TEST_LOCK_mchk so that asynchronous machine-check handlers never call ppc_exc_wrapup() (and the dispatcher). We don't want to disable MSR_ME ever (to avoid checkstops) and hence asynchronous MEs must not use OS services anyways. added and commented new variables 'ppc_exc_intr_stack_size' 'ppc_exc_crit_always_enabled'.

| | | | | | | | | * new-exceptions/bspsupport/irq.c: don't disable irqs at the interrupt controller (PIC) during initialization -- this caused problems where some BSPs's BSP_disable_irq_at_pic() routine did not ignore IRQ lines associated with cascaded PICs. Rely on the BSP (BSP_setup_the_pic()) to provide a good initial setup.

| | | | | | | | | | | | | | | * new-exceptions/bspsupport/ppc_exc_asm_macros.h, new-exceptions/bspsupport/ppc_exc.S, new-exceptions/bspsupport/README, new-exceptions/bspsupport/ppc_exc_hdl.c: Thomas Doerfler clarified (thanks!) that raising an exception and executing the 1st instruction is not an atomical operation. I added a fix to the code that checks if a lower-priority interrupt is under way: we now not only test if the 'lock' variable was set but also check if the interrupted PC points to the 'write lock' instruction. Added more comments and updated README.
