Numerous new and changed files, and many files and whole subdirectory trees removed. All old device drivers are removed, replaced using the OSKit device driver libraries. All the changes on this page are a unified interdependent set of changes turning GNUmach into OSKit-Mach, but since there are so many changes I have put them in separate paragraphs roughly divided by topic. * oskit: New subdirectory of support code using OSKit interfaces, and providing OSKit bottom-end interfaces for using components in Mach. * oskit/ds_asyncio.c: New file. * oskit/ds_block.c: New file. * oskit/ds_bus.c: New file. * oskit/ds_mem.c: New file. * oskit/ds_net.c: New file. * oskit/ds_osenv.c: New file. * oskit/ds_oskit.h: New file. * oskit/ds_partition.c: New file. * oskit/ds_request.c: New file. * oskit/ds_request.h: New file. * oskit/ds_routines.c: New file. * oskit/ds_stream.c: New file. * oskit/osenv_irq.c: New file. * oskit/osenv_log.c: New file. * oskit/osenv_mem.c: New file. * oskit/osenv_sleep.c: New file. * oskit/osenv_synch.c: New file. * oskit/pc/osenv_bell.c: New file. * oskit/pc/osenv_timer.c: New file. * oskit/x86/main.c: New file. * oskit/kmsg.c: New file. This is an oskit-based kernel logging device in the style of Linux's /proc/kmsg magical file. It is the backend used for all logging output from oskit components. Front-end changes for device and miscellaneous support code changes: * device/dev_hdr.h: Rewritten. * device/dev_pager.c: Revamped to support only the new uniform oskit-based device_t interface, one flavor of pager. Commented out unused routines. * device/device_init.c (device_service_create): Don't call dev_lookup_init. * device/net_io.c (if_init_queues): Moved here from defunct subrs.c. (net_set_filter): Call net_kmsg_more before successful return, to make sure the very first packet buffer gets allocated. * kern/startup.c: Remove XPR cruft, panic_init, printf_init. * kern/syscall_sw.c: Add some missing headers. * kern/mach_clock.c: Deliver oskit clock ticks at splsoftclock. Miscellaneous cleanups & changes to use convenient OSKit facilities. * i386/i386/cswitch.S: Assembler macro nits. * i386/i386/fpu.c, i386/i386/fpu.h: Magic instruction macro nits. * i386/i386/fpe_linkage.c: Use OSKit structure and constant names. * i386/i386/i386sym.sym: Likewise. * i386/i386/idt-gen.h: Likewise. * i386/i386/idt.c: Likewise. * i386/i386/idt_inittab.S: Likewise. * i386/i386/gdt.c: Likewise. * i386/i386/gdt.h: Likewise. * i386/i386/ldt.c: Likewise. * i386/i386/ldt.h: Likewise. * i386/i386/user_ldt.h: Likewise. * i386/i386/user_ldt.c: Likewise. * i386/i386/locore.S: Likewise. * i386/i386/iopb.c: Likewise. * i386/i386/iopb.h: Likewise. * i386/i386/mp_desc.c: Likewise. * i386/i386/mp_desc.h: Likewise. * i386/i386/io_emulate.c: Likewise. * i386/i386/io_emulate.h: Likewise. * i386/i386/pcb.c: Likewise. * i386/i386/pit.c: Likewise. * i386/i386/pic.c: Likewise. * i386/i386/spl.S: Likewise. * i386/i386/thread.h: Likewise. * i386/i386at/int_init.c: Likewise. * i386/i386at/interrupt.S: Likewise. * i386/i386at/pic_isa.c: Likewise. * kern/kalloc.c: Likewise. * i386/intel/pmap.h: Likewise. * i386/i386/trap.c: Likewise. Remove much cruft, TTD & KDB. Call oskit gdb_trap handler if enabled. * i386/i386/vm_param.h: Use <oskit/x86/base_vm.h> for defns. * i386/i386/hardclock.c: Clean up unused PS2 & LINUX_DEV cruft. * i386/include/mach/i386/vm_param.h: #undef PAGE_SHIFT in case of conflicting defn from the oskit. * kern/assert.h: Rewritten using <oskit/c/assert.h>. * kern/debug.h: Use <oskit/gdb.h>. * kern/machine.c: Likewise. * kern/bootstrap.c: Use oskit headers for multiboot and exec stuff. (boot_info): Fix type, not a pointer. (bootstrap_create): Fix uses. (get_compat_strings): Initialize to "UNKNOWN" in case nothing seen. (user_bootstrap): Increase buffer sizes for device/file name prompts. * vm/vm_object.c: Remove XPR cruft. Changes to the physical page pool code to share a pool of available memory kept in contiguous chunks with oskit code (drivers). The pageout daemon moves memory between the shared pool (the LMM) and the vm_page_queue_free list to keep some available for either use, but vm_page_grab can always steal a page directly from the LMM if the pageout daemon is not keeping the free list full enough. The interesting action here goes on in oskit/osenv_mem.c. * vm/vm_page.h (vm_page_queue_free_count, vm_page_unqueued_count): Declare new variables. (vm_page_free_count): Now a macro. * vm/vm_pageout.c (vm_pageout_scan): Call consider_lmm_collect. * vm/vm_resident.c: Remove XPR cruft. (vm_page_queue_free_count, vm_page_unqueued_count): New variables. (vm_page_free_count): Variable removed. (pmap_startup): Commented out. (vm_page_grab): When the queue is empty, call vm_page_grab_oskit_page. Also wakeup the pageout daemon whenever vm_page_queue_free_count < vm_page_unqueued_count. (vm_page_release): Use vm_page_queue_free_count for vm_page_free_count. (vm_page_module_init): Make the vm_page_zone collectable. * i386/intel/pmap.c: Use oskit types, macros, and variables that apply. (INVALIDATE_TLB): Macro replaced with inline function. Attempt to use INVLPG instruction if available. (kernel_pte_global): New variable. (pmap_bootstrap): Set it if processor supports INTEL_PTE_GLOBAL bit, and set PGE flag in %cr4 to enable using it. Use it for page table entries in the kernel portion of address space. (pmap_create): Use pmap_page_table_page_alloc to get a direct-mapped physical page for the page directory. (pmap_destroy): Deallocate accordingly. (pmap_enter): Zero-fill new page table pages. Use kernel_pte_global if allocating in the kernel_pmap. * ipc/mach_port.c (mach_port_insert_right): IO_VALID -> IP_VALID. * kern/ipc_tt.c (mach_ports_register): Add a cast. Associated configure/build changes for reorganizations. * configure.in: Generate config.h file instead of -D switches. (--enable-kdb, --enable-kmsg): Options removed. (--enable-smp): New argument, sets MAXCPUS, defines NCPUS. (--enable-fpe): New argument, defines FPE. Add check for a sufficiently new installed oskit version. (OSKIT_LIBDIR): New variable, substituted. Comment out AC_CONFIG_SUBDIRS call. * configure: Regenerated. * acconfig.h, config.h.in: New files, used by autoheader and configure. * cpus.h: New file, uses configure-generated config.h for values. * include/device/device_error_reply.defs: New file. * device/device_error_reply.cli: New file. Well-typed error replies. * version.c (version): Changed to "GNUmach 1.2.90-OSKit". * Makefile.in, i386/Makefrag: Substantially revamped for many added and removed modules, new linking rules to use oskit libraries. * i386/Files, i386/Subdirs: Updated. Removed all old device drivers, hardware support code, and miscellaneous things that can be replaced by using OSKit libraries. Also removed much cruft that was already unused in GNUmach. Removed unused "XPR" kernel logging facility. * chips, ddb, linux, scsi, util: Whole directory trees all removed. * device/blkio.c: Obsolete file removed. * device/buf.h: Likewise. * device/chario.c: Likewise. * device/cirbuf.c: Likewise. * device/cirbuf.h: Likewise. * device/conf.h: Likewise. * device/cons.c: Likewise. * device/cons.h: Likewise. * device/dev_forward.defs: Likewise. * device/dev_lookup.c: Likewise. * device/dev_name.c: Likewise. * device/dk_label.c: Likewise. * device/ds_routines.c: Likewise. * device/errno.h: Likewise. * device/io_req.h: Likewise. * device/kmsg.c: Likewise. * device/kmsg.h: Likewise. * device/param.h: Likewise. * device/subrs.c: Likewise. * device/tty.h: Likewise. * i386/Makefile.in: Likewise. * i386/README-Drivers: Likewise. * i386/configure: Likewise. * i386/configure.in: Likewise. * i386/i386/_setjmp.S: Likewise. * i386/i386/db_disasm.c: Likewise. * i386/i386/db_interface.c: Likewise. * i386/i386/db_machdep.h: Likewise. * i386/i386/db_trace.c: Likewise. * i386/i386/debug.h: Likewise. * i386/i386/debug_i386.c: Likewise. * i386/i386/debug_trace.S: Likewise. * i386/i386/fpe.b: Likewise. * i386/i386/fpe.b_elf: Likewise. * i386/i386/io_map.c: Likewise. * i386/i386/ktss.c: Likewise. * i386/i386/ktss.h: Likewise. * i386/i386/kttd_interface.c: Likewise. * i386/i386/kttd_machdep.h: Likewise. * i386/i386/loose_ends.c: Likewise. * i386/i386/pic.h: Likewise. * i386/i386/pit.h: Likewise. * i386/i386/proc_reg.h: Likewise. * i386/i386/seg.c: Likewise. * i386/i386/seg.h: Likewise. * i386/i386/setjmp.h: Likewise. * i386/i386/timer.h: Likewise. * i386/i386/tss.h: Likewise. * i386/i386/xpr.h: Likewise. * i386/i386at/asm_startup.h: Likewise. * i386/i386at/autoconf.c: Likewise. * i386/i386at/blit.c: Likewise. * i386/i386at/blitreg.h: Likewise. * i386/i386at/blituser.h: Likewise. * i386/i386at/blitvar.h: Likewise. * i386/i386at/boothdr.S: Likewise. * i386/i386at/com.c: Likewise. * i386/i386at/comreg.h: Likewise. * i386/i386at/conf.c: Likewise. * i386/i386at/cons_conf.c: Likewise. * i386/i386at/cram.h: Likewise. * i386/i386at/dev_hdr.h: Likewise. * i386/i386at/device_emul.h: Likewise. * i386/i386at/disk.h: Likewise. * i386/i386at/ds8390.h: Likewise. * i386/i386at/eisa.h: Likewise. * i386/i386at/fd.c: Likewise. * i386/i386at/fdreg.h: Likewise. * i386/i386at/i386at_ds_routines.c: Likewise. * i386/i386at/i8250.h: Likewise. * i386/i386at/i82586.h: Likewise. * i386/i386at/if_3c501.c: Likewise. * i386/i386at/if_3c501.h: Likewise. * i386/i386at/if_3c503.h: Likewise. * i386/i386at/if_de6c.c: Likewise. * i386/i386at/if_de6c.h: Likewise. * i386/i386at/if_de6s.S: Likewise. * i386/i386at/if_ne.c: Likewise. * i386/i386at/if_nereg.h: Likewise. * i386/i386at/if_ns8390.c: Likewise. * i386/i386at/if_ns8390.h: Likewise. * i386/i386at/if_par.c: Likewise. * i386/i386at/if_par.h: Likewise. * i386/i386at/if_pc586.c: Likewise. * i386/i386at/if_pc586.h: Likewise. * i386/i386at/if_wd8003.h: Likewise. * i386/i386at/immc.c: Likewise. * i386/i386at/iopl.c: Likewise. * i386/i386at/kd.c: Likewise. * i386/i386at/kd.h: Likewise. * i386/i386at/kd_event.c: Likewise. * i386/i386at/kd_mouse.c: Likewise. * i386/i386at/kd_queue.c: Likewise. * i386/i386at/kd_queue.h: Likewise. * i386/i386at/kdasm.S: Likewise. * i386/i386at/kdsoft.h: Likewise. * i386/i386at/lpr.c: Likewise. * i386/i386at/lprreg.h: Likewise. * i386/i386at/model_dep.c: Likewise. * i386/i386at/nfd.c: Likewise. * i386/i386at/nfdreg.h: Likewise. * i386/i386at/nhd.c: Likewise. * i386/i386at/nhdreg.h: Likewise. * i386/i386at/phys_mem_grab_page.c: Likewise. * i386/i386at/rtc.c: Likewise. * i386/i386at/rtc.h: Likewise. * kern/debug.c: Likewise. * kern/printf.c: Likewise. * kern/xpr.c: Likewise. * kern/xpr.h: Likewise. * debian/control, debian/rules: First crack at setting things up to build an oskit-mach package instead of gnumach.
