* Update mach_debug interfaces to use struct.Flavio Cruz2022-11-252-0/+16
| | | | | | | | | | | | | | | | | | | | | | The new interfaces will be compatible both with a 64 bits kernel and userland and 64 bits kernel and 32 bit userland. Also removed many of the uses of natural_t where an unsigned int suffices. Ideally we should replace natural_t with something more portable such as uintptr_t or a basic int type for counters since for the most part we don't need counters to have the same width as the pointer type. * i386/include/mach/i386/vm_types.h: Define rpc_unsigned_long. * include/mach/mach_types.defs: Define type rpc_vm_offset_t. * include/mach_debug/hash_info.h: Use unsigned int instead of natural_t. * include/mach_debug/mach_debug_types.defs: Update cache_info_t, hash_info_bucket_t, vm_region_info_t, vm_object_info_t and vm_page_info_t to use struct. * include/mach_debug/slab_info.h: Use rpc_vm_size_t and rpc_unsigned_long for compatibility with 32 bits userland. * include/mach_debug/vm_info.h: Update struct fields to use the correct types and avoid natural_t whenever we just want to keep a count of something.

* Fix inclusability of <mach/mach_types.h>Samuel Thibault2022-08-282-8/+63
| | | | | Now that mach/machine/vm_types.h uses stdint types, we have to ship a header that defines them.
* add rpc_versions for vm typesLuca Dariz2022-08-271-4/+33
| | | | | | | | | | | | | | | * vm_types.h: add new types and conversion functions * mach_types.defs: adapt vm types depending on kernel user/server * vm_info.h: adapt rpc structure to have uniformly-sized members also on 64-bit * x86_64/configfrag.c: add new option to select the user-space variant. Note that with this change the user-space interface is somehow fixed, i.e. it can't support 32-bit and 64-bit tasks at the same time. If this would be needed at some point, this change needs to be reworked. Signed-off-by: Luca Dariz <luca@orpolo.org> Message-Id: <20220403145955.120742-3-luca@orpolo.org>

* x86: Move fp_reg.h static assertions to .c fileSamuel Thibault2020-12-011-2/+0

* x86: Keep fp_regs.h standaloneSamuel Thibault2020-12-011-6/+4
| | | | | | | | | We cannot include stdint.h in fp_regs.h since this is included by mach_types.h for bootstrapping, before we have stdint.h from glibc. * i386/include/mach/i386/fp_reg.h: Do not include <stdint.h> (XSAVE_XCOMP_BV_COMPACT, struct i386_xfp_xstate_header): Use unsigned long long instead of uint64_t.
* x86: Fix initialization of new threadsSamuel Thibault2020-11-291-0/+1
| | | | | | | | | | | | | | | | | | | fninit does not clear MMX/SSE/AVX registers, so we have to use rstor to clear them when starting a new thread. Along the way, we can as well just have a default state to be loaded in each new thread. * i386/include/mach/i386/fp_reg.h (XSAVE_XCOMP_BV_COMPACT): New macro. * i386/i386/fpu.h (fp_default_state): New variable declaration. * i386/i386/fpu.c (fp_default_state): New variable.

(i386_xfp_save): Add xsave fields. * i386/i386/fpu.c (fp_xsave_support): New variable. (init_fpu): Look for XSAVE feature; if available, get the supported parts and set fp_kind to FP_387X. (fpu_module_init): Set ifps_cache alignment to alignof(struct i386_fpsave_state). (fpu_set_state): Make sure to clear all the ifps structure. Reuse the FP_387FX for the FP_387X case. (fpu_get_state, fpexterrflt, fpastintr, fp_state_alloc): Reuse the FP_387FX for the FP_387X case. (fp_save): When fp_kind is FP_387X, use xsave. (fp_load): When fp_kind is FP_387X, use xrstor. Reuse the FP_387FX for the FP_387X case.
* fpu: Rename FP_387X to FP_387FXSamuel Thibault2020-11-281-1/+2
| | | | | | | | | | | To leave FP_387X for XSAVE-supporting CPU (as opposed to FXSAVE-supporting CPU) * i386/include/mach/i386/fp_reg.h (FP_387X): Rename to FP_387FX. (FP_387X): New macro. * i386/i386/fpu.c (init_fpu, fpu_set_state, fpu_get_state, fpexterrflt, fpastintr, fp_save, fp_load, fp_state_alloc): Update accordingly. * i386/i386/fpu.h (fpu_save_context): Likewise.

* Add vm_allocate_contiguous RPCSamuel Thibault2020-07-092-0/+10
| | | | | | | | | | | | | | | | | This allows privileged userland drivers to allocate buffers for e.g. DMA, and thus need them to be physically contiguous and get their physical address. Initial work by Zheng Da, reworked by Richard Braun, Damien Zammit, and myself. * doc/mach.texi (vm_allocate_contiguous): New RPC. * i386/include/mach/i386/machine_types.defs (rpc_phys_addr_t): New type. * i386/include/mach/i386/vm_types.h [!MACH_KERNEL] (phys_addr_t): Set type to 64bits.

* Restore vm_size_t to natural_tSamuel Thibault2020-03-311-0/+4
| | | | | | | | | | | Plenty of places such as glibc RPC uses currently assume that vm_size_t is a natural_t (thus int on 32bit), not an unsigned long. * i386/include/mach/i386/vm_types.h (vm_size_t) [!__x86_64__]: Set type to natural_t. * device/dev_page.c (device_pager_data_request): Cast vm_size_t to unsigned long. * i386/i386at/model_dep.c (c_boot_entry): Likewise.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change replaces the historical page allocator with a buddy allocator implemented in vm/vm_page.c.
