1999-01-31Can send and receive packets but fails when TDA wraps. There appearsJoel Sherrill2-45/+113
to be a problem with overwriting the TX descriptors during an RX.

1998-11-19Patch from Eric Norum <eric@skatter.usask.ca>:Joel Sherrill2-4/+6
1) Socket timeout field changed from `short' to `long'. This makes longer timeouts possible. With a 1 kHz system clock the old system allowed timeouts only up to a little over 30 seconds! This change is a slightly cleaned-up version of the patch proposed by Ian Lance Taylor. 2) Major changes to BOOTP/DHCP reply handling. Now supports much of RFC2132. These changes were done at the request of, and with the assistance of, Erik Ivanenko. If you're making changes, you might want to change the network supplement Essentially just do a global search and replace of BOOTP with BOOTP/DHCP.

Finally I am through: I have found the last bugs that made RTEMS- 4.0-beta3 start on my ppc403 board from ROM. So now the '403 support is up to date again. Roughly I have added the following features: - support for the on-chip interrupt controller (in a separate module) - interrupt support for the console device - termios support for the console device ============================================== Since the BSP behaivour changed in some details (console no longer is polling, other memory layout etc) I have created a new BSP "helas403" rather than changing the "papyrus" BSP. The old "polled" console driver still sticks around in "console.c.polled" To get the BSP up and running, I had to create the new BSP files (derived from papyrus). Besides that, the following source areas have been changed: - c/src/lib/libcpu/powerpc/ppc403: changes to console driver, small changes to clock driver, new "ictrl" interrupt controller driver - c/src/exec/score/cpu/powerpc/ppc.h: some small changes (added ppc403 characteristics like a exception vector prefix register, some special register definitions). I am quite sure, they are compatible with the existing sources, although I did not check - c/src/exec/score/cpu/powerpc/cpu.c: There is one severe limitation in the exception entries: Due to the current code arrangement, the "branch absolute" to the ISR handler may only jump to the first 128MByte or the last 128MByte of the 4GByte address range. When the ppc403 is running out of ROM, the ROM functions are located in the last 128MByte (0xFFF00000 and up). These addresses were not handled correctly (sign reduced) in "install_raw_handler". The change I added should work on existing ppc BSPs aswell... - c/src/lib/libc/termios.c: During my tests, I added one change you sent me, so this patch will already be incorporated in the current source tree. There are some smaller changes, see the attached diff file. ========================================= Concerning the GNU toolchain: I tried several tool chains. Finally I almost succeeded with egcs-1.0.3a with patch egcs-1.0.3-rtems-diff-19980527 I had to add the following lines to the egcs files. Without them configure complaint that the cross compiler could not generate executable output. - additional lines needed in egcs distribution in file gcc/config/rs6000/rtems.h: +++ lines start #undef STARTFILE_DEFAULT_SPEC #define STARTFILE_DEFAULT_SPEC "ecrti.o%s" #undef ENDFILE_DEFAULT_SPEC #define ENDFILE_DEFAULT_SPEC "ecrtn.o%s" ++++ lines end As far as I have seen in the Changelog of egcs, you have recently sent two patches affecting the powerpc support, but they were added in the wrong order.... :-( egcs-19980628 with patch egcs-19980628-rtems-diff-19980707 does not work! I used binutils 2.9.1 with patch binutils-2.9.1-rtems-diff-19980515 (binutils 2.8.1 does not work, internal error in gas) and newlib-1.8.0 with patch newlib-1.8.0-rtems-diff-19980707 Finally I had to poke a line in the "bit" script, since, on my LINUX machine, the GNU make is only available as "make", not as "gmake"... For all the tools and newlib I selected configuration "powerpc- rtems". -------------------------------------------- IMD Ingenieurbuero fuer Microcomputertechnik Thomas Doerfler Herbststrasse 8 D-82178 Puchheim Germany email: td@imd.m.isar.de
1998-09-30Changed based on patch from pc386 linkcmds from Ian Lance TaylorJoel Sherrill2-1/+2
<ian@airs.com>: The pc386 linker scripts omits .gnu.linkonce.r* sections. It's not a big deal, but they should be treated like .rodata sections. ELF versions of g++ generate them for static constants defined in template classes, such as string::npos.
1998-09-11Updates to tree to make it build with all desired changes and the conversionJoel Sherrill5-788/+835
of the SONIC driver to the new FreeBSD stack instead of KA9Q.

1998-08-13Enable TX interrupts only when we need TDAs.Joel Sherrill1-1/+0
1998-08-13Cleaned up some debugging stuff.Joel Sherrill1-23/+15
Redid interrupt handler to read imr/isr once and to write the imr once.
1998-08-12Removed spurious prints and cleaned up XXX.Joel Sherrill1-11/+10
1998-08-12Added more debug information. There are probably debug prints left in.Joel Sherrill1-24/+53
Fixed one important bug. After wrapping the RX Descriptors all had the EOL bit set which resulted in everything slowing down massively.
1998-08-12Fixed bug where the last link of the RDA was not initialized properly.Joel Sherrill1-15/+30
1998-08-11Added SONIC_DEBUG_DESCRIPTORS and changed debug level.Joel Sherrill1-3/+11
1998-08-10Survives 16-20 packets. Appears to be ok on TX buffer management.Joel Sherrill1-11/+16
Problem appears to be on the RX buffer initialization side.
1998-08-10Added printsJoel Sherrill1-1/+2
1998-08-10Can now reply to multiple successive pings successfully without being inJoel Sherrill2-29/+22
promiscuous mode. It still dies somewhere between 16 and 20 pings.
1998-08-10replies to ping -- forced into prosmiscuous modeJoel Sherrill1-13/+21
1998-08-08Reordered some stuff.Joel Sherrill1-7/+10
1998-08-08Changed debug level.Joel Sherrill2-36/+96
Moved CAM Descriptor types to sonic.h. CAM memory is now malloced to insure it shares the same upper address bits. Removed increment of RX interrupt count on TX interrupt path. Added SONIC_DEBUG_FRAGMENTS and SONIC_DEBUG_CAM conditionals. Fixed bugs in fragment manipulation. First bug was that the pad overwrote the last fragment. The second bug was that the link information overwrote the size of the last fragment. Rewrote initialization of TDA to simplify it.
1998-08-06Removed SonicRegisters structure since we now use register indicesJoel Sherrill1-83/+15
and access routines. Added revision constants. Added in_use and EOL field values.
1998-08-06Enabled specific types of debug info.Joel Sherrill1-31/+55
Added pointer to RDA to sonic structure. Added macro names for values used in the in_use field of RDA entries. Rewrote the RX Descriptor Area initialization loop. Added a check to barf if this is a Rev B sonic chip. Enabled check that the CAM was properly loaded.
1998-08-06Changed debug enable macros to support individually enabling differentJoel Sherrill1-15/+30
types of debug information. Removed call to rtems_panic which was based on checking a variable which was no longer being set.
1998-08-06Card Resource Register was a 16-bit register not a 32-bit one.Joel Sherrill5-28/+36
Used existing constants for bits on the register.
1998-08-06Added support for the Card Resource Register. The new probe routinesJoel Sherrill5-8/+107
check for the presence of the DUART, SCC, and RTC. The SONIC check needs to be added in the future as the network driver is libchip'ed.
1998-08-05Added constants which made the multiple bit settings more readableJoel Sherrill1-0/+25
for the Data Configuration Register (DCR).
1998-08-05DCR setting changed to match what the DY-4 Firmware initialized it to.Joel Sherrill1-135/+259
This primarily included setting the state of the programmable outputs and the RX and TX FIFO depths. Moved all of the TX, RX, and RRA data structure initialization to before the hardware initialization. As part of this, the hardware initialization was consolidated. More than likely, some of this movement broke stuff. Used constants added to sonic.h which gave more logical names to some of the register bit settings. Switched to calloc to insure the data areas where initialized to 0. Commented out a panic check in the RX server which may or may not have been right. Increased the size of the CAM initialization area. It is possible that this could be decreased or code added to handle the management of multiple hardware addresses. Added sonic read and write register routines which aid greatly in debugging and provide the core for the eventual movement of this driver to libchip. Added debug code to the read and write register routines which can print the value read from or written to a register. This code also prints the register name which significantly eases reading the log.
1998-08-03Switched to read/write register routines and added some basic debugJoel Sherrill2-332/+473
help.
