* * shared/vectors/vectors.S: mask high bits when calculatingTill Straumann2006-01-051-2/+3
| | | | | the exception vector number to yield correct result even if the vectors reside in the upper area (0xfff00000; psim).

| | | | | | | | | * shared/irq/irq_init.c, shared/openpic/openpic.h shared/openpic/openpic.c: The 8240's EPIC has a 'serial' mode of operation for multiplexing 16 interrupt lines. This introduces a pipeline delay which can cause spurious interrupts unless ending the interrupt cycle (EOI) is delayed accordingly.
* 2005-12-01 Till Straumann <strauman@slac.stanford.edu>Till Straumann2005-12-023-26/+64
| | | | | | | | | * shared/vectors/vectors.h, shared/vectors/vectors.S, shared/vectors/vectors_init.c: Reduced size of default prologue (some exceptions, e.g., altivec unavail.) are only 0x20 bytes apart. Also introduced a modified prologue that switches r0..r3 shadowing off (r0..r3 undefined on certain 603e variants when incurring a TLB miss).
* 2005-11-29 Till Straumann <strauman@slac.stanford.edu>Till Straumann2005-11-302-0/+4
| | | | | | * shared/irq/irq_asm.S, shared/vectors/vectors.S: Clear CR[6] before invoking high-level handler to make sure no varargs fn callee assumes there are FP arguments.

| | | | | | | | | | | * shared/vme/README, shared/vme/vme_universe.c: New files. * Makefile.am, motorola_powerpc/Makefile.am, mvme5500/vme/vmeconfig.c, shared/vme/VME.h, shared/vme/VMEConfig.h, shared/vme/vmeconfig.c: Several VME related upgrades and fixes, hopefully addressing PR#835: Separated API, API-implementation by a specific VME bridge driver and BSP-specific configuration of the driver into different files, describing their purpose in a README. All of these changes use the upgraded vmeUniverse.c driver.

| | | | | | | | | | | | | | * shared/motorola/motorola.c, shared/pci/detect_raven_bridge.c, shared/pci/pci.c, shared/pci/pci.h, shared/pci/pcifinddevice.c: Several PCI enhancements and fixes: all BSP flavors now use the generic clear_hostbridge_errors() routine (this means that only polling memory probing is possible [see detect_raven_bridge.c for details]). Interrupt fixup routine now supports multi-function devices. Interrupt fixup routine now honours a flag/option so that wrong firmware values can be overridden. Fixed irq routing table for mvme2100 [PMC]. Added irq routing table for mvme2300. Added a BSP_pciScan() routine that executes a user callback on each non-empty slot/fun. Added BSP_pciConfigDump() to display basic config headers.
* 2005-11-03 <strauman@slac.stanford.edu>Till Straumann2005-11-042-14/+3
| | | | | | | | * shared/console/reboot.c, shared/start/start.S: Fixed PR#845; !!enable MMU!! on mvme2100 - this is very important. Otherwise, all accesses are write-back cached [incl. memory-mapped devices]. (Prerequisite were the changes to shared/startup/bspstart.c just below.) Implemented rtemsReboot() for mvme2100.
* 2005-11-03 <strauman@slac.stanford.edu>Till Straumann2005-11-045-338/+381
| | | | | | | | | | * shared/irq/openpic_i8259_irq.c: New file. * ChangeLog, Makefile.am, motorola_powerpc/ChangeLog, motorola_powerpc/Makefile.am, shared/irq/irq.c, shared/irq/irq.h, shared/irq/irq_asm.S, shared/irq/irq_init.c: Separated openpic/i8259 specifica from generic irq handling into openpic_i8259_irq.c; added some compilation conditionals to help BSPs without ISA to omit ISA interrupts and calling i8259 code.
* 2005-11-03 <strauman@slac.stanford.edu>Till Straumann2005-11-043-99/+151
| | | | | | | | | | | * shared/startup/pretaskinghook.c, shared/startup/zerobss.c: New files. * Makefile.am, shared/startup/bspstart.c: Split pretaskinghook and zerobss into separate, reusable files; Fixed #PR837 (set exception in ram flag before initializing exceptions); Setup DBATs early, they are needed to access peripherals (Allows mvme2100 to use MMU); moved VME initialization into pretasking hook so that shared interrupts can be used for VME [shared IRQ facility needs functional workspace].
* 2005-11-03 <strauman@slac.stanford.edu>Till Straumann2005-11-042-11/+25
| | | | | | | | | * mvme5500/irq/irq.h, psim/irq/irq.h, shared/console/uart.c, shared/irq/irq.h: Renamed BSP_ISA_UART_COMx_IRQ -> BSP_UART_COMx_IRQ (uart driver is ISA independent). Removed ugly #ifdef mvme2100. Added test for BSP_UART_USE_SHARED_IRQS symbol which a BSP can define to request that the serial interrupt be shared.
* 2005-11-03 straumanatslacdotstanforddoteduTill Straumann2005-11-031-1/+5
| | | | | | | * shared/vectors/vectors.S: when returning from an exception, reload stack pointer with value from exception frame instead of adding a fixed value. -- maybe the exception handler modified the frame with good reason (e.g., gdb pushed a dummy frame).

| | | | | | | | | PR 833/bsps * irq/irq_asm.S: Currently, all (new exception) BSPs explicitely enable the FPU across the user ISR but DONT save/restore the FPU context. Any use of the FPU fron the user handler (e.g., due to GCC optimizations) result in corruption. The fix results in an exception in such cases (user ISR must explicitely save/enable/restore FPU).
