1998-08-19Patch from Eric Valette <valette@crf.canon.fr>:Joel Sherrill2-53/+49
- Use the "hlt" instruction for the Idle thread, - Optimise interrupt PATH leadding to thread wakeup, - Preparation for Intel exception management that should come before the end of the week...
1998-08-19Patch from Aleksey <qqi@world.std.com>:Joel Sherrill2-10/+45
This patch has same changes as one I sent to you earlier plus it fixes _heap_size problem for pc386 we had discussed earlier. Now, _heap_size is defined and set to 0 in pc386/startup/bspstart.c It can be patched to desireable value in binary image. If it is left unpatched, then startup code will determine size of memory (on the assumption that at least 2MB are present) and use max possible heap.
1998-08-19Patch from Aleksey <qqi@world.std.com>:Joel Sherrill8-21/+34
It fixes netboot build problem, KA9Q configuration for pc386, some compiler wardning, it also removed some stuff ifdef'ed with '#if 0'.

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.

1998-08-08Reordered some stuff.Joel Sherrill1-7/+10
1998-08-08Corrected spacing.Joel Sherrill1-1/+1
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.
1998-08-05Patch from Eric Valette <valette@crf.canon.fr> which brings the i386ex BSPJoel Sherrill21-70/+354
inline with the new IRQ structure.
1998-08-05Automatic CPU type detection code from Eric Valette <valette@crf.canon.fr>.Joel Sherrill7-22/+27
Enabled on the pc386.

1998-07-30Added a hint to continue writing this.Joel Sherrill1-0/+2
1998-07-30Added getRealTime() and setRealTime().Joel Sherrill2-18/+99
Reimplemented checkRealTime() to use RTEMS internal routine.
1998-07-30Changed clock rate from 32 Khz to 1 Mhz.Joel Sherrill2-6/+6
Registers are at 8 byte boundaries NOT 4 as initially configured.

existing TOD interface.
1998-07-29Cleaned up comment.Joel Sherrill1-4/+5
Modified open so it uses a local variable rather than modifying a parameter.
