2001-05-14 Till Straumann <strauman@slac.stanford.edu>
|
||||
|
||||
* 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_.

There are various issues regarding this port:
|
||||
|
||||
|
||||
|
||||
1) Legal
|
||||
|
||||
This port is written by Andrew Bray <andy@i-cubed.co.uk>, and
|
||||
is copyright 1995 i-cubed ltd.
|
||||
|
||||
This port was later updated by Joel Sherrill <joel@OARcorp.com>
|
||||
to test the support for the PPC603, PPC603e, and MPC604. This
|
||||
was tested on the PowerPC simulator PSIM and a VMEbus single board
|
||||
computer.
|
||||
|
||||
2) CPU support.
|
||||
|
||||
This release fully supports the PPC403GA, PPC403GB, PPC603, PPC603e,
|
||||
MPC604, MPC750, and numerous MPC8xx processors. A good faith attempt
|
||||
has been made to include support other models based upon available
|
||||
documentation including the MPC5xx. There are two interrupt structures
|
||||
supported by the PowerPC port. The newer structure is supported by
|
||||
all the MPC750 and MPC604 BSPs. This structure is required to use
|
||||
the RDBG remote debugging support.
|
||||
|
||||
This port was originally written and tested on the PPC403GA (using
|
||||
software floating point). Current ports are tested primarily on
|
||||
60x CPUs using the PowerPC simulator PSIM.
|
||||
|
||||
Andrew Bray received assistance during the initial porting effort
|
||||
from IBM and Blue Micro and we would like to gratefully acknowledge
|
||||
that help.
|
||||
|
||||
The support for the PPC602 processor is incomplete as only sketchy
|
||||
data is currently available. Perhaps this model has been dropped.
|
||||
|
||||
3) Application Binary Interface
|
||||
|
||||
In the context of RTEMS, the ABI is of interest for the following
|
||||
aspects:
|
||||
|
||||
a) Register usage. Which registers are used to provide static variable
|
||||
linkage, stack pointer etc.
|
||||
|
||||
b) Function calling convention. How parameters are passed, how function
|
||||
variables should be invoked, how values are returned, etc.
|
||||
|
||||
c) Stack frame layout.
|
||||
|
||||
I am aware of a number of ABIs for the PowerPC:
|
||||
|
||||
a) The PowerOpen ABI. This is the original Power ABI used on the RS/6000.
|
||||
This is the only ABI supported by versions of GCC before 2.7.0.
|
||||
|
||||
b) The SVR4 ABI. This is the ABI defined by SunSoft for the Solaris port
|
||||
to the PowerPC.
|
||||
|
||||
c) The Embedded ABI. This is an embedded ABI for PowerPC use, which has no
|
||||
operating system interface defined. It is promoted by SunSoft, Motorola,
|
||||
and Cygnus Support. Cygnus are porting the GNU toolchain to this ABI.
|
||||
|
||||
d) GCC 2.7.0. This compiler is partway along the road to supporting the EABI,
|
||||
but is currently halfway in between.
|
||||
|
||||
This port was built and tested using the PowerOpen ABI, with the following
|
||||
caveat: we used an ELF assembler and linker. So some attention may be
|
||||
required on the assembler files to get them through a traditional (XCOFF)
|
||||
PowerOpen assembler.
|
||||
|
||||
This port contains support for the other ABIs, but this may prove to be
|
||||
incomplete as it is untested.
|
||||
|
||||
The RTEMS PowerPC port supports EABI as the primary ABI. The powerpc-rtems
|
||||
GNU toolset configuration is EABI.

Todo list:

Maybe decode external interrupts like the HPPA does.
