* new-exceptions/bspsupport/nested_irq_test.c: adjusted
wrong irq name/number calculation.
2007-12-10 Till Straumann <strauman@slac.stanford.edu>
* new-exceptions/bspsupport/ppc_exc_hdl.c: make sure
RI is set in the exception frame and panic if it isn't
(state info might have been lost). This only affects
classic PPC.
2007-12-10 Till Straumann <strauman@slac.stanford.edu>
* new-exceptions/bspsupport/README,
new-exceptions/bspsupport/ppc_exc_bspsupp.h
new-exceptions/bspsupport/vectors_init.c:
added crude test to make sure MMU maps memory as
write-back enabled.
2007-12-09 Till Straumann <strauman@slac.stanford.edu>
* new-exceptions/bspsupport/ppc_exc_test.c,
new-exceptions/bspsupport/vectors_init.c,
new-exceptions/bspsupport/ppc_exc_bspsupp.h,
new-exceptions/bspsupport/README,
new-exceptions/bspsupport/irq_supp.h:
Added README and some comments; now use TRAP exception
in ppc_exc_test.c so that it works on PSIM.
2007-12-08 Till Straumann <strauman@slac.stanford.edu>
* irq_supp.h: was moved from libbsp/powerpc/shared/irq to
libcpu/powerpc/new-exceptions/bspsupport.
2007-12-08 Till Straumann <strauman@slac.stanford.edu>
* new-exceptions/bspsupport/irq.c,
new-exceptions/bspsupport/ppc_exc_bspsupp.h,
new-exceptions/bspsupport/ppc_exc_hdl.c:
fixed some mismatching signed/unsigned types.
2007-12-08 Till Straumann <strauman@slac.stanford.edu>
* new-exceptions/bspsupport/, new-exceptions/bspsupport/ppc_exc.S,
new-exceptions/bspsupport/ppc_exc_test.c,

new-exceptions/bspsupport/vectors_init.c,

new-exceptions/bspsupport/ppc_exc_bspsupp.h,
new-exceptions/bspsupport/ppc_exc_hdl.c,
new-exceptions/bspsupport/ppc_exc_asm_macros.h,
new-exceptions/bspsupport/nested_irq_test.c:
New files. Added 'middleware' code for helping BSPs implement
exception and interrupt handling and implementing the 'new'
RTEMS IRQ API (which I personally dislike).
2007-12-08 Till Straumann <strauman@slac.stanford.edu>
* new-exceptions/e500_raw_exc_init.c, new-exceptions/raw_exception.c,
shared/include/cpuIdent.c, shared/include/cpuIdent.h:
Added different kinds of 'bookE' to the ppc_cpu_is_bookE feature
check; unfortunately...
2007-12-07 Till Straumann <strauman@slac.stanford.edu>
* Makefile.am: must not add e500_raw_exc_init.c to
xyz_SOURCES for mpc5xx
2007-12-06 Till Straumann <strauman@slac.stanford.edu>
* shared/include/cpuIdent.h, shared/include/cpuIdent.c:
added feature check for 603 'TLBMISS exception GPRS shadowing'.
2007-12-06 Till Straumann <strauman@slac.stanford.edu>
* new-exceptions/raw_exception.c, new-exceptions/raw_exception.h:
Removed all #ifdef <cpu_flavor>. All exception vectors are now
always defined.
Changed implementation of <cpu>_vector_is_valid() from 'case'
statements to table lookup.
Replaced 'ASM_VECTORS_CRITICAL' by a variable
'bsp_raw_vector_is_405_critical' which is set at run-time.
Removed PPC_MSR_EXC_BITS. The exception handling code
(libbsp/shared/vectors/vectors.S and ../irq/irq_asm.S) now
has a run-time check for these bits.
Both files are now free of #if <cpu_flavor> constructs.
2007-12-05 Till Straumann <strauman@slac.stanford.edu>
* Makefile.am, configure.ac, preinstall.am,
new-exceptions/e500_raw_exc_init.c: Started adding
support for e500 CPU. Most stuff is borrowed from mpc6xx.
2007-12-05 Till Straumann <strauman@slac.stanford.edu>
* rtems/powerpc/powerpc.h: added a #ifdef __ppc_generic
branch. The goal is eventually to make this the starting
point for cleanup (remove as many branches as possible;
replace by run-time tests if necessary).
2007-12-05 Joel Sherrill <joel.sherrill@OARcorp.com>
* new-exceptions/raw_exception.c: Conditionalize call to
e500_setup_raw_exceptions() since that is not even in the tree yet.
2007-12-05 Joel Sherrill <joel.sherrill@OARcorp.com>
* new-exceptions/raw_exception.c: Conditionalize some BOOKE vectors.
2007-12-05 Till Straumann <strauman@slac.stanford.edu>
* new-exceptions/raw_exception.c, new-exceptions/raw_exception.h:
Added typedef for exception classes (classic, critical, ...
synchronous / asynchronous). ppc_vector_is_valid() now returns
the appropriate class.
2007-12-05 Till Straumann <strauman@slac.stanford.edu>
* new-exceptions/raw_exception.c: made all <cpu>_vector_is_valid()
subroutines that are called from ppc_vector_is_valid() 'static'.
2007-12-05 Till Straumann <strauman@slac.stanford.edu>
* new-exceptions/raw_exception.c, new-exceptions/raw_exception.h:
Qualified all exception vector symbols that are only defined
#ifdef <cpu_flavor> with <cpu_flavor> in the symbol name.
If the special flavor __ppc_generic is effective the ALL
vector symbols are available and ppc_vector_is_valid() works
for all supported CPUs (run-time check).
This is work towards a #ifdef <cpu_flavor> free libcpu and
exception framework.
2007-12-04 Joel Sherrill <joel.sherrill@OARcorp.com>
* mpc5xx/console-generic/console-generic.c, mpc8260/timer/timer.c,
new-exceptions/cpu.c, old-exceptions/cpu.c: Move interrupt_stack_size
field from CPU Table to Configuration Table. Eliminate CPU Table from
all ports. Delete references to CPU Table in all forms.
2007-12-04 Thomas Doerfler <Thomas.Doerfler@embedded-brains.de>
* mpc83xx/spi/mpc83xx_spidrv.c, mpc83xx/spi/mpc83xx_spidrv.h:
added missing files
2007-12-03 Joel Sherrill <joel.sherrill@OARcorp.com>
* mpc5xx/console-generic/console-generic.c: Moved most of the remaining
CPU Table fields to the Configuration Table. This included
pretasking_hook, predriver_hook, postdriver_hook, idle_task,
do_zero_of_workspace, extra_mpci_receive_server_stack,
stack_allocate_hook, and stack_free_hook. As a side-effect of this
effort some multiprocessing code was made conditional and some style
clean up occurred.
2007-12-03 Joel Sherrill <joel.sherrill@oarcorp.com>
* shared/include/cpuIdent.h: Correct conditionals and includes.
2007-11-30 Till Straumann <strauman@slac.stanford.edu>
* new-exceptions/raw_exception.c, new-exceptions/raw_exception.h,
old-exception/cpu.c: define bsp_exceptions_in_RAM variable.
This is probably only used by the simulator (were else
can you install something to ROM ??).
2007-11-30 Till Straumann <strauman@slac.stanford.edu>
* mpc6xx/mmu/bat.c, mpc6xx/mmu/pte121.c: use new
feature-checks from cpuIdent.h rather than filtering
CPU types when checking for availability of high BATs
and an MMU with hardware page-table lookup.
2007-11-30 Till Straumann <strauman@slac.stanford.edu>
* mpc6xx/clock/c_clock.c, mpc6xx/clock/c_clock.h:
added support for bookE/ppc405 style CPUs where the
decrementer works slightly differently.
2007-11-29 Till Straumann <strauman@slac.stanford.edu>
* mpc6xx/exceptions/raw_exception.c,
mpc6xx/exceptions/raw_exception.h: removed. mpc6xx
uses generic version in new-exceptions.
2007-11-29 Till Straumann <strauman@slac.stanford.edu>
* shared/include/cpuIdent.h, shared/include/cpuIdent.c:
Added a simple 'feature check' facility. Code should
not check for a particular CPU type if possible but
check the respective feature bit (e.g., 'has_altivec').
This makes it much less cumbersome to add more CPU
types in the future.
2007-11-29 Till Straumann <strauman@slac.stanford.edu>
* mpc6xx/mmu/bat.c, mpc6xx/mmu/bat.h: Added support
for setting & reading IBATs.
2007-11-28 Joel Sherrill <joel.sherrill@OARcorp.com>
* ppc403/clock/clock.c: Now compiles and links.

ppc403/ictrl/ictrl.c, ppc403/irq/ictrl.c, ppc403/timer/timer.c,
ppc403/tty_drv/tty_drv.c: Eliminate PowerPC specific elements from
the CPU Table. They have been replaced with variables named bsp_XXX
as needed.
2007-11-28 Till Straumann <strauman@slac.stanford.edu>
* shared/src/cache.c: removed redundant mpc8xx versions
of flush/invalidate 1 cache line routines.
2007-11-13 Till Straumann <strauman@slac.stanford.edu>
* shared/src/cache.c: moved generic operations
(flush/invalidate 1 data line, invalidate 1 inst. line)
from #ifdef <cpu_flavor> to general section (all CPUs).
2007-11-13 Till Straumann <strauman@slac.stanford.edu>
* shared/src/cache_.h: include <libcpu/cache.h> only
#ifdef _OLD_EXCEPTIONS - no need for <libcpu/cache.h>
otherwise.
2007-11-13 Till Straumann <strauman@slac.stanford.edu>
* shared/include/byteorder.h: fixed wrong pointer-type
of ld_le32() (uint16_t* -> uint32_t*).
2007-11-06 Till Straumann <strauman@slac.stanford.edu>
* mpc5xx/irq/irq.c, mpc5xx/exceptions/raw_exception.c,
new-exceptions/raw_exception.c: test for non-NULL-ness before calling
'on'/'off' methods so that users don't have to provide
no-ops if they don't want this feature.

ppc403/ictrl/ictrl.c, ppc403/irq/ictrl.c: Code outside of cpukit
should use the public API for
rtems_interrupt_disable/rtems_interrupt_enable. By bypassing the
public API and directly accessing _CPU_ISR_Disable and
_CPU_ISR_Enable, they were bypassing the compiler memory barrier
directive which could lead to problems. This patch also changes the
type of the variable passed into these routines and addresses minor
style issues.

requirements when manipulating the caches against the book

2006-06-19 Till Straumann <strauman@slac.stanford.edu>
* mpc6xx/exceptions/raw_exception.c, mpc6xx/exceptions/raw_exception.h:
Added altivec exception. Unfortunately, this doesn't fit
the normal scheme of vector = exception # << 8. So we picked
an unused vector number (currently 0xa) where we map the special
vector 0xf20 (altivec).
2006-06-19 Till Straumann <strauman@slac.stanford.edu>
* new-exceptions/cpu.c, new-exceptions/cpu_asm.S: Never
allow the FPU to be switched on for integer-only tasks
(new gcc may use FP regs implicitly).
FP context switch may be called from environment with no
FPU available (ISR, int-only task) - switch FPU on
for the switch and restore MSR_FP after it's done.

* mpc6xx/clock/c_clock.c: The PPC decrementer must be reloaded on

since the decrementer crossed zero in order to adjust the value to
be re-loaded. Without the patch, the effective system clock cycle is

* mpc6xx/mmu/pte121.c, mpc6xx/mmu/pte121.h: New files. Missed in
merge of PR213.
2001-05-14 Till Straumann <strauman@slac.stanford.edu>
* rtems/powerpc/registers.h, rtems/score/ppc.h: Per PR213, add the
following: - support for the MPC74000 (AKA G4); there is no AltiVec
support yet, however. - the cache flushing assembly code uses
hardware-flush on the G4. Also, a couple of hardcoded numerical
values were replaced by more readable symbolic constants. - extended
interrupt-disabled code section so enclose the entire cache
flush/invalidate procedure (as recommended by the book). This is not
(latency) critical as it is only used by init code but prevents
possible corruption. - Trivial page table support as been added.
(1:1 effective-virtual-physical address mapping which is only useful
only on CPUs which feature hardware TLB replacement, e.g. >604.
This allows for write-protecting memory regions, e.g. text/ro-data
which makes catching corruptors a lot easier. It also frees one
DBAT/IBAT and gives more flexibility for setting up address maps :
-) - setdbat() allows changing BAT0 also (since the BSP may use a
page table, BAT0 could be available...). - asm_setdbatX() violated
the SVR ABI by using r20 as a scratch register; changed for r0 -
according to the book, a context synchronizing instruction is
necessary prior to and after changing a DBAT -> isync added
* new-exceptions/cpu.c: Per PR211 fix saving/restoring floating
point context. The fpsave and fprestore routines are only used in a
executing context which _is_ fp and hence has the FPU enabled. The
current behavior required the FPU always to be on which is very
dangerous if lazy context switching is used. [Joel Note: Some
ports explicitly enabled the FPU in the FP save and restore routines
to avoid this.] The patch also makes sure (on powerpc only) that the
FPU is disabled for integer tasks. Note that this is crucial if
deferred fp context switching is used. Otherwise, fp context
corruption may go undetected! Also note that even tasks which merely
push/pop FP registers to/from the stack without modifying them still
MUST be FP tasks - otherwise (if lazy FP context switching is used),
FP register corruption (of other, FP, tasks may occur)! Furthermore,
(on PPC) by default, lazy FP context save/restore is _disabled_.
* shared/include/io.h: Per PR215 address the following issues: -
_IO_BASE, _ISA_MEM_BASE and PCI_DRAM_OFFSET are no longer defined by
libcpu (powerpc/shared/include/io.h) but by the BSP (who is the only
one to know the values) - the affected BSP (shared/motorola) headers
have been fixed in a separate "libbsp/powerpc/shared" patch. - the
DEC 21140 driver (libchip/network/dec21140.c) has been fixed to use
PCI_DRAM_OFFSET instead of PREP_PCI_DRAM_OFFSET. and PCI_MEM_BASE
instead of PREP_ISA_MEM_BASE. PCI_MEM_BASE is to be defined by the
BSP who is using this driver. - the DEC driver also has been fixed
to use the newer rtems_bsp_delay_in_bus_cycles() instead of the
obsolete delay_in_bus_cycles().

* shared/include/cpu.h: Added ifndef ASM.
2001-04-03 Joel Sherrill <joel@OARcorp.com>
* Closed PR57. The hack is OK as it allows a BSP to override or not
at its discretion.
* Per PR94, all rtems/score/CPUtypes.h are named
rtems/score/types.h.
* Per PR94, all rtems/score/CPUtypes.h are named
rtems/score/types.h.
* mpc8xx/timer/timer.c: Removed #warning declaring providing a
default definition for the macros
rtems_cpu_configuration_get_timer_least_valid and
rtems_cpu_configuration_get_timer_average_overhead.
* old-exceptions/rtems/score/cpu.h,
new-exceptions/rtems/score/cpu.h: Account for name change.
2001-03-30 Eric Valette <valette@crf.canon.fr>
* mpc8xx/vectors/Makefile.am,
mpc8xx/vectors/README, mpc8xx/vectors/align_h.S
mpc8xx/vectors/vectors.S: These files were removed in support of
switching the mpc8xx to the use the "new exception processing
model."
* configure.in, mpc6xx/mmu/bat.h, mpc8xx/Makefile.am,
mpc8xx/clock/clock.c, mpc8xx/console-generic/console-generic.c,
mpc8xx/include/mpc8xx.h, mpc8xx/mmu/mmu.c,
new_exception_processing/cpu.h, shared/include/byteorder.h,
wrapup/Makefile.am: This is conversion of the mpc8xx CPU to the "new
exception processing model."
* mpc8xx/exceptions/Makefile.am,
mpc8xx/exceptions/asm_utils.S, mpc8xx/exceptions/raw_exception.c,
mpc8xx/exceptions/raw_exception.h: New files.
2001-02-27 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* mpc505/ictrl/Makefile.am, mpc6xx/clock/Makefile.am,
mpc6xx/exceptions/Makefile.am, mpc6xx/mmu/Makefile.am,
mpc8xx/include/Makefile.am, new_exception_processing/Makefile.am,
old_exception_processing/Makefile.am, pc403/ictrl/Makefile.am,
shared/include/Makefile.am, shared/src/Makefile.am: Apply *_HEADERS
instead of *H_FILES.
2001-01-03 Joel Sherrill <joel@OARcorp.com>
* new_exception_processing/cpu.h, old_exception_processing/cpu.c:
old_exception_processing/cpu.h, Added _CPU_Initialize_vectors(). In
particular, spurious vector initialization had to be moved on old
exception processing model.
2000-11-09 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
2000-11-02 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* Makefile.am: Switch to ACLOCAL_AMFLAGS = -I
$(RTEMS_TOPdir)/aclocal.
2000-10-26 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros. Switch to
GNU canonicalization.
2000-10-20 Joel Sherrill <joel@OARcorp.com>
* mpc8xx/console-generic/console-generic.c: Avoid use of BSP
definitions and rely on the new routine
mbx8xx_console_get_configuration() to get information. This routine
was formerly incorrectly called
mbx8xx_console_use_maximum_buffer_size(). binding to the exception
code.
* configure.in, Makefile.am: Explicitly specify whether an
RTEMS_CPU_MODEL is using old or new exception processing. This is
important because when building multilib, you do not know the
RTEMS_CPU_MODEL. So everything built in a multilib'ed RTEMS must be
independent of the exception model and allow for late binding to the
exception code.
2000-10-18 Sergei Organov <osv@javad.ru>
* Added full support for MPC505.
* configure.in, mpc505/Makefile.am: Modified to reflect ictrl
addition.
* old_exception_processing/Makefile.am: Account for ppc_offs.h.
* old_exception_processing/cpu_asm.S: Offsets moved to ppc_offs.h.
* mpc505/timer/timer.c: Use <rtems.h>, not "rtems.h".
* mpc505/vectors/vectors.S: Now use constants for exception numbers.
* mpc505/ictrl: New directory.
* old_exception_processing/ppc_offs.h: New file.
* old_exception_processing/cpu.h: Make Nest and Disable levels
volatile.
* mpc505/vectors/Makefile.am: alignment exception handler now
included.
* mpc505/ictrl/Makefile.am,
mpc505/ictrl/ictrl.c, mpc505/ictrl/ictrl.h: New files.
2000-10-18 Joel Sherrill <joel@OARcorp.com>
* mpc8xx/console-generic/console-generic.c: Removed include of
<bsp.h> by adding BSP dependent routine
mbx8xx_console_use_maximum_buffer_size() which can be hard coded or
check non-volatile memory for configuration.
* mpc8xx/console-generic/console-generic.c: Removed warnings.
* mpc6xx/clock/c_clock.h: Removed commented out reference to
<bsp.h>.
* mpc6xx/timer/timer.c, mpc6xx/timer/timer.c: Ditto.
* mpc6xx/clock/c_clock.c, mpc6xx/clock/c_clock.h: Removed use of
bsp.h and replaced it with use of proper interfaces or explicit
externs of required functions and data.
2000-09-04 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* mpc505/timer/Makefile.am, mpc505/vectors/Makefile.am,

2000-08-11 Charles-Antoine Gauthier <charles.gauthier@nrc.ca>
* mpc8xx/console-generic/console-generic.c: Add support for
configuration parameters in NVRAM
2000-08-10 Charles-Antoine Gauthier <charles.gauthier@nrc.ca>
* mpx8xx/console-generic/console-generic.c(m8xx_uart_pollWrite):
Flush actual buffer.
* mpx8xx/console-generic/console-generic.c: Addition of support for
shared printk and no termios.
2000-06-08 Eric Valette <valette@crf.canon.fr>
* mpc8xx/console-generic/console-generic.c: The printk/printf did
not work when loaded by EPPCBUG. They did work when loaded with the
BDM debugger. I suspected EPPBUG made some nasty things like
patching Communication processor microcode... Anyway, the attached
patch: 1) Enables to have printk nearly immediately after boot, 2)
Make printf work automagically (I do not know why except I make a
different initialization for printk that should be overwritten by
console init later ?) I let the default to be using EPPCBUG embedded
firmware to boot and using this printk early enabler code
(LOADED_BY_EPPCBUG and EARLY_CONSOLE) are on.
