Changes in hp300

Changes in hp300 http://nxr.netbsd.org/rss/src/sys/arch/hp300/ en Copyright 2005 Java The new pmap_68k is no longer experimental. Sun Aug 16 00:00:00 UTC 2026 thorpej All M68040 configs require FPSP, and all M68060 configs require M060SP, so just make M68040 and M68060 dependent on their respective software packages rather than having to duplicate the options across every kernel config. Wed Aug 05 01:00:00 UTC 2026 thorpej Now that all m68k platforms are using the commonn db_memrw.c, declare that file in the common files.m68k. Mon Jul 06 16:00:00 UTC 2026 thorpej Provide common defaults for NKMEMPAGES_MIN_DEFAULT and NKMEMPAGES_MAX_DEFAULT for all m68k platforms. Defaults for all 68010 come from Sun2, defaults for everyone else come from hp300, and per-platform overrides for min and max are provided (and preserved). Fri Jul 03 17:00:00 UTC 2026 thorpej fix typos in comments. Sat May 23 06:00:00 UTC 2026 andvar Hide platform vmparam differences away from user-space and modules. For modules that need to know USRSTACK (exec / compat modules), provide a way to get that via a variable initialized in cpu_startup(). Sun May 03 19:00:00 UTC 2026 thorpej Centralize the definition of VM_{MIN,MAX}_KERNEL_ADDRESS. Thu Apr 30 05:00:00 UTC 2026 thorpej Re-factor cpu_reboot(). Platforms can provide optional hooks for halt (to exit back to firmware) and power-off (to, um, power off). Tue Apr 28 03:00:00 UTC 2026 thorpej Re-factor all of the badaddr() variants into a single badaddr_read() that takes an access size and can return a value. Add a badaddr_write() that similarly takes a size. Sun Apr 26 00:00:00 UTC 2026 thorpej Centralize the declaration of "nofault". Sun Apr 26 10:00:00 UTC 2026 thorpej Re-factor the various m68k platforms' identifycpu() functions, and bring some consistency to how the CPU/FPU/MMU/cache information is displayed. Each platform now provides a machine_set_model() function that is called from cpu_startup_common(). This function is respondible for calling cpu_setmodel() with platform-specific model description. Then, common code is responsible for printing the model information, along with the CPU and cache info, but separately (and this is no longer included in the hw.model sysctl node; at least it's now consistent!) Some examples: Qemu 10.1.2 Virt platform MC68040+MMU+FPU, 4k+4k on-chip I/D caches (hw.model == "Qemu 10.1.2 Virt platform") Motorola MVME-147 MC68030 CPU+MMU @ 25MHz, MC68882 FPU (hw.model == "Motorola MVME-147") HP 9000/350 MC68020 CPU @ 25MHz, HP MMU, MC68881 FPU @ 20MHz External 32K virtual-address cache (hw.model == "HP 9000/350") HP 9000/433s MC68040 CPU+MMU+FPU @ 33MHz, 4K+4K on-chip I/D caches (hw.model == "HP 9000/433s") A hook is provided for customized model banners: Model: sun2 {120,170} MC68010 CPU @ 10MHz, Sun MMU (hw.model == "sun2 {120,170}") Model: sun3 160 MC68020 CPU @ 16.67MHz, Sun MMU, MC68881 FPU (hw.model == "sun3 160") Model: sun3 50 MC68020 CPU @ 16MHz, Sun MMU, emulated FPU (hw.model == "sun3 50") An additional hook is provided for more complicated model banners: SONY NET WORK STATION, Model NWS-1710, Machine ID #123456 MC68030 CPU+MMU @ 25MHz, MC68882 FPU (hw.model == "NWS-1710") The Sun banners are likely to change once a different way to get the "kernel_arch" is provided for the installer miniroot script, in which case they will match more closely what the firmware prints at start-up. Prep work for adopting the generic banner() routine is included here; that change will come in a future commit. Thu Apr 23 02:00:00 UTC 2026 thorpej Re-factor genassym.cf into common m68k definitions and platform-specific ones. Mon Apr 20 09:00:00 UTC 2026 thorpej Centralize the declaration of msgbufaddr for m68k platforms. Sun Apr 05 14:00:00 UTC 2026 thorpej Don't use mmutype as a proxy for cputype when deciding what to do with the cache. Sun Mar 29 14:00:00 UTC 2026 thorpej switch_subr.s is now a standlone file, so the boilerplate in each locore.s that pulled it in is unnecessary. Sun Mar 29 03:00:00 UTC 2026 thorpej I am giving up attempting to bend the kernel build machinery to my will so that assym.h can be safely included by libkern assembly sources. So, instead, redundantly define __HAVE_M68K_BROKEN_RMC in multiple places so that all the things that need to key off of it can. Wed Dec 03 02:00:00 UTC 2025 thorpej Add a trimmed down configuration file for the small 68020-based machines. Sat Nov 29 23:00:00 UTC 2025 thorpej Fix various typos, mainly in comments. Sat Nov 29 22:00:00 UTC 2025 andvar extent(9) -> vmem(9) Sat Nov 29 19:00:00 UTC 2025 thorpej Remove the advertising clause from Adam Glass's license. Many thanks to Adam for agreeing to this.
