Raw Normal View History

This are the build infrastructure changes to allow to use the Intel C/C++ compiler (lang/icc) to build the kernel. The icc CPUTYPE CFLAGS use icc v7 syntax, icc v8 moans about them, but doesn't abort. They also produce CPU specific code (new instructions of the CPU, not only CPU specific scheduling), so if you get coredumps with signal 4 (SIGILL, illegal instruction) you've used the wrong CPUTYPE. Incarnations of this patch survive gcc compiles and my make universe. I use it on my desktop. To use it update share/mk, add /usr/local/intel/compiler70/ia32/bin (icc v7, works) or /usr/local/intel_cc_80/bin (icc v8, doesn't work) to your PATH, make sure you have a new kernel compile directory (e.g. MYKERNEL_icc) and run CFLAGS="-O2 -ip" CC=icc make depend CFLAGS="-O2 -ip" CC=icc make in it. Don't compile with -ipo, the build infrastructure uses ld directly to link the kernel and the modules, but -ipo needs the link step to be performed with Intel's linker. Problems with icc v8: - panic: npx0 cannot be emulated on an SMP system - UP: first start of /bin/sh results in a FP exception Parts of this commit contains suggestions or submissions from Marius Strobl <marius@alchemy.franken.de>.

Makefile gram.y scan.l sequencer.h symbol.c symbol.h aic7xxx_asm.c: New sequencer assembler for the aic7xxx adapters. This assembler performs some amount of register type checking, allows bit manipulation of symbolic constants, and generates "patch tables" for conditionalized downloading of portions of the program. This makes it easier to take full advantage of the different features of the aic7xxx cards without imposing run time penalies or being bound to the small memory footprints of the low end cards for features like target mode. aic7xxx.reg: New, assembler parsed, register definitions fo the aic7xxx cards. This was done primarily in anticipation of 7810 support which will have a different register layout, but should be able to use the same assembler. The kernel aic7xxx driver consumes a generated file in the compile directory to get the definitions of the register locations. aic7xxx.seq: Convert to the slighly different syntax of the new assembler. Conditionalize SCB_PAGING, ultra, and twin features which shaves quite a bit of space once the program is downloaded. Add code to leave the selection hardware enabled during reconnects that win bus arbitration. This ensures that we will rearbitrate as soon as the bus goes free instead of delaying for a bit. When we expect the bus to go free, perform all of the cleanup associated with that event "up front" and enter a loop awaiting bus free. If we see a REQ first, complain, but attempt to continue. This will hopefully address, or at least help diagnose, the "target didn't send identify" messages that have been reported. Spelling corrections obtained from NetBSD.

Add support to aicasm for "downloaded constants". These are immediate operands that are set during seqeuncer program download instead of at assembly time. Convert the sequencer code to use" downloaded constants" for four run time constants that vary depending on the board type. This frees up 4 bytes of sequencer scratch ram space where these constants used to be stored and also removes the additional instructions required to load their values into the accumulator prior to using them. Remove the REJBYTE sram variable. The host driver can just as easly read the accumulator to get this value. The scratch ram savings is important as the old code used to clober the SCSICONF register on 274X cards which sits near the top of scratch ram space. The SCSICONF register controls bus termination, and clobbering it is not a good thing. Now we have 4 bytes to spare. This should fix the reported problems with cards that don't have devices attached to them failing with a stream of "Somone reset bus X" messages. Doug Ledford determined the cause of the problem, fixes by me.
