This maps virtual addresses to physical - * addresses directly using 4mb tlb entries, with the physical address encoded - * in the lower 43 bits of virtual address. These mappings are convenient - * because they do not require page tables, and because they never change they - * do not require tlb flushes. However, since these mappings are cacheable, - * we must ensure that all pages accessed this way are either not double - * mapped, or that all other mappings have virtual color equal to physical - * color, in order to avoid creating illegal aliases in the data cache. - * - * VM_MIN_KERNEL_ADDRESS and VM_MAX_KERNEL_ADDRESS define the start and end of - * mappable kernel virtual address space. VM_MIN_KERNEL_ADDRESS is basically - * arbitrary, a convenient address is chosen which allows both the kernel text - * and data and the prom's address space to be mapped with 1 4mb tsb page. - * VM_MAX_KERNEL_ADDRESS is variable, computed at startup time based on the - * amount of physical memory available. Each 4mb tsb page provides 1g of - * virtual address space, with the only practical limit being available - * phsyical memory. - * - * VM_MIN_PROM_ADDRESS and VM_MAX_PROM_ADDRESS define the start and end of the - * prom address space. On startup the prom's mappings are duplicated in the - * kernel tsb, to allow prom memory to be accessed normally by the kernel. - * - * VM_MIN_USER_ADDRESS and VM_MAX_USER_ADDRESS define the start and end of the - * user address space. There are some hardware errata about using addresses - * at the boundary of the va hole, so we allow just under 43 bits of user - * address space. Note that the kernel and user address spaces overlap, but - * this doesn't matter because they use different tlb contexts, and because - * the kernel address space is not mapped into each process' address space. - */ -#define VM_MIN_ADDRESS (0x0000000000000000UL) -#define VM_MAX_ADDRESS (0xffffffffffffffffUL) - -#define VM_MIN_DIRECT_ADDRESS (0xfffff80000000000UL) -#define VM_MAX_DIRECT_ADDRESS (VM_MAX_ADDRESS) - -#define VM_MIN_KERNEL_ADDRESS (0x00000000c0000000UL) -#define VM_MAX_KERNEL_ADDRESS (vm_max_kernel_address) - -#define VM_MIN_PROM_ADDRESS (0x00000000f0000000UL) -#define VM_MAX_PROM_ADDRESS (0x00000000ffffffffUL) - -#define VM_MIN_USER_ADDRESS (0x0000000000000000UL) -#define VM_MAX_USER_ADDRESS (0x000007fe00000000UL) - -#define VM_MINUSER_ADDRESS (VM_MIN_USER_ADDRESS) -#define VM_MAXUSER_ADDRESS (VM_MAX_USER_ADDRESS) - -#define KERNBASE (VM_MIN_KERNEL_ADDRESS) -#define PROMBASE (VM_MIN_PROM_ADDRESS) -#define USRSTACK (VM_MAX_USER_ADDRESS) - -/* - * How many physical pages per kmem arena virtual page. - */ -#ifndef VM_KMEM_SIZE_SCALE -#define VM_KMEM_SIZE_SCALE (tsb_kernel_ldd_phys == 0 ? 3 : 2) -#endif - -/* - * Optional floor (in bytes) on the size of the kmem arena. - */ -#ifndef VM_KMEM_SIZE_MIN -#define VM_KMEM_SIZE_MIN (16 * 1024 * 1024) -#endif - -/* - * Optional ceiling (in bytes) on the size of the kmem arena: 60% of the - * kernel map. - */ -#ifndef VM_KMEM_SIZE_MAX -#define VM_KMEM_SIZE_MAX ((VM_MAX_KERNEL_ADDRESS - \ - VM_MIN_KERNEL_ADDRESS + 1) * 3 / 5) -#endif - -/* - * Initial pagein size of beginning of executable file. - */ -#ifndef VM_INITIAL_PAGEIN -#define VM_INITIAL_PAGEIN 16 -#endif - -#define UMA_MD_SMALL_ALLOC - -extern u_int tsb_kernel_ldd_phys; -extern vm_offset_t vm_max_kernel_address; - -/* - * Older sparc64 machines have a virtually indexed L1 data cache of 16KB. - * Consequently, mapping the same physical page multiple times may have - * caching disabled. - */ -#define ZERO_REGION_SIZE PAGE_SIZE - -#include <machine/tlb.h> - -#define SFBUF -#define SFBUF_MAP - -#define PMAP_HAS_DMAP dcache_color_ignore -#define PHYS_TO_DMAP(x) (TLB_PHYS_TO_DIRECT(x)) - -#endif /* !_MACHINE_VMPARAM_H_ */ diff --git a/sys/sparc64/include/watch.h b/sys/sparc64/include/watch.h deleted file mode 100644 index 1adb2e1c6670..000000000000 --- a/sys/sparc64/include/watch.h +++ /dev/null @@ -1,43 +0,0 @@ -/*- - * SPDX-License-Identifier: BSD-2-Clause-FreeBSD - * - * Copyright 2001 by Thomas Moestl <tmm@FreeBSD.org>.
