Hello Ralf, others,
We are porting the new 2.4.0 series Linux kernel to Algorithmics
P4032 board with MIPS processor (QED-RM5230). We ported
2.4.0-test5 kernel. We already succeeded in porting the following
code, partly based on the changes made by MIPS Technologies
for the 2.2.12/P5064 patch:
1. Memory management & timer related stuff
2. Support for PCI devices
3. Support of the onboard SCSI controller
4. Support of the onboard Ethernet controller
5. Support for the Serial lines
We've got a problem with the foating point support. With either
soft or hard FP support, some FP operation generate an exception,
e.g. cvt.w.d.
We tried both with and without support of FPE soft module,
compiled for R46xx and R5000 processors (As far as I
understand there is no difference in FP support in the kernel
for these processor types).
We did not have these problems with the (2.2.12 MIPS Technologies
based) port we made to this same board.
We would appreciate any ideas how to solve the problem.
Algorithmics P4032 board consists of:
1. QED - RM5230 (the documentation claims that it fully
supports MIPS IV level)
2. V3 V962PBC PCI adapter
3. Onboard Symbios 53c810a SCSI chipset
4. Onboard Tulip 21041 Ethernet controller
5. Combi I/O controller for 2 RS232 serial ports, centronics
parallel port and disk drive.
Best regards and thanks in advance,
Evgeni Eskenazi,
Arnold Niessen
