1*63559SmckusickHere is a list of hp300 specific kernel compilation options and what they 2*63559Smckusickmean: 3*63559Smckusick 4*63559SmckusickHAVEVAC 5*63559Smckusick Compiles in support for virtually addressed cache (VAC) found on 6*63559Smckusick hp320 and 350 machines. Should only be defined when HP320 and/or 7*63559Smckusick HP350 is. 8*63559Smckusick 9*63559SmckusickHP320 10*63559Smckusick Support for old hp320 machines: 16mhz 68020, HP MMU, 16mhz 68881 11*63559Smckusick and VAC. Compiles in support for a VAC, HP MMU, and the 98620A 12*63559Smckusick 16-bit DMA channel. Forces the definition of HAVEVAC. 13*63559Smckusick 14*63559SmckusickHP350 15*63559Smckusick Support for old hp350 machines: 25mhz 68020, HP MMU, 20mhz 68881 16*63559Smckusick and VAC. Compiles in support for a VAC and the HP MMU. Differs 17*63559Smckusick from HP320 in that it has no support for 16-bit DMA controller. 18*63559Smckusick Forces the definition of HAVEVAC. 19*63559Smckusick 20*63559SmckusickHP330 21*63559Smckusick Support for old hp330 (and 318/319) machines: 16mhz 68020, 68551 PMMU 22*63559Smckusick and 16mhz 68881. Compiles in support for PMMU. 23*63559Smckusick 24*63559SmckusickHP360 25*63559Smckusick Support for old hp360 (and 340) machines: 25mhz 68030+MMU and 25mhz 26*63559Smckusick 68882. Compiles in support for PMMU and 68030. Differs from HP330 27*63559Smckusick in support for 68030 on-chip data cache. 28*63559Smckusick 29*63559SmckusickHP370 30*63559Smckusick Support for old hp370 (and current 345/375/400) machines: 33 (50) mhz 31*63559Smckusick 68030+MMU and 33 (50) mhz 68882. Compiles in support for PMMU, 68030 32*63559Smckusick and off-chip physically addressed cache. Differs from 360 in only one 33*63559Smckusick place, in dealing with flushing the external cache. 34*63559Smckusick 35*63559SmckusickHP380 36*63559Smckusick Support for "current" hp380/425 (and 433) machines: 25 (33) mhz 68040 37*63559Smckusick with MMU/FPU. Compiles in support for 68040. 38*63559Smckusick 39*63559SmckusickHPFPLIB 40*63559Smckusick Compiles in support to link with HP-UX's version of Motorola's 68040 41*63559Smckusick FP emulation library (hp300/hpux_float.o). Kernel will build and run 42*63559Smckusick without this option, but many binaries will core dump. Should not be 43*63559Smckusick defined unless HP380 is. 44*63559Smckusick 45*63559Smckusick 46*63559SmckusickUSELEDS 47*63559Smckusick Twinkle the hp4xx front panel (or hp3xx internal) LEDs in the HP 48*63559Smckusick designated way. Somewhat frivolous, but the heartbeat LED is 49*63559Smckusick useful to see if your machine is alive. 50*63559Smckusick 51*63559SmckusickPANICBUTTON 52*63559Smckusick Compiles in code which will enable a "force-crash" HIL keyboard 53*63559Smckusick sequence. When the Reset key is typed twice in succession (within 54*63559Smckusick half a second) the kernel will panic. Note that the HIL Reset key 55*63559Smckusick sends a NMI to the processor which will get the CPUs attention no 56*63559Smckusick matter what it is doing (i.e. as long as it isn't halted). Alas, 57*63559Smckusick also note that the NMI is only sent when the keyboard is in "cooked" 58*63559Smckusick (ITE) mode. If it is in "raw" mode (i.e. X-server is running) the 59*63559Smckusick Reset key is just another keypress event. A cheezy substitute in 60*63559Smckusick this case is holding down the upper right-most unlabeled key and 61*63559Smckusick then pressing the unlabeled key to its left. Note that this only 62*63559Smckusick works if HIL (level 1) interrupts are not masked. 63*63559Smckusick 64*63559SmckusickDEBUG 65*63559Smckusick Compiles in a variety of consistency checks and debug printfs 66*63559Smckusick throughout the hp300 MD code and device drivers. 67*63559Smckusick 68*63559SmckusickHPUXCOMPAT 69*63559Smckusick Enables HP-UX binary compatibility mode. Allows a variety of 70*63559Smckusick "recent" HP-UX binaries to be run unchanged. Due to the 71*63559Smckusick evolutionary and "as-needed" nature of this code, "recent" is 72*63559Smckusick anywhere from release 6.2 to 8.0 of HP-UX. It will run 8.0 73*63559Smckusick shared-library binaries (assuming all the necessary shared-libraries 74*63559Smckusick are installed in the filesystem). 75*63559Smckusick 76*63559SmckusickCOMPAT_OHPUX 77*63559Smckusick Compile in old 4.2-ish HP-UX (pre-6.0?) compatibility code. 78*63559Smckusick 79*63559SmckusickFPCOPROC 80*63559Smckusick Compile in code to support the 68881 and above FPU. Should always 81*63559Smckusick be defined, since all supported SPUs have one. Don't even know if 82*63559Smckusick it will compile, much less work, without this option. Defined in 83*63559Smckusick the prototype makefile (hp300/conf/Makefile.hp300). 84*63559Smckusick 85*63559SmckusickDCMSTATS 86*63559Smckusick Compile in code to collect a variety of transmit/receive statistics 87*63559Smckusick for the 98642 4-port MUX. 88*63559Smckusick 89*63559SmckusickWAITHIST 90*63559Smckusick Compile in code to collect statistics about the distribution of 91*63559Smckusick wait-times for various busy waits in the SCSI host-adaptor driver. 92*63559Smckusick 93*63559SmckusickSTACKCHECK 94*63559Smckusick Enables two types of kernel stack checking in hp300/hp300/locore.s: 95*63559Smckusick 1. stack "overflow". On every clock interrupt we ensure that 96*63559Smckusick the current kernel stack has not grown into the user struct 97*63559Smckusick page, i.e. size exceeded UPAGES-1 pages. 98*63559Smckusick 2. stack "underflow". Before every rte to user mode we ensure 99*63559Smckusick that we will be exactly at the base of the stack after the 100*63559Smckusick exception frame has been popped. 101*63559Smckusick This option can degrade performance considerably, use it only if 102*63559Smckusick you suspect a problem with kernel stacks. 103
