kern/slab: directmap update

2015-08-15T10:43:27Z

The main impact of the direct physical mapping on the kmem module is the slab size computation. The page allocator requires the allocation size to be a power-of-two above the page size since it uses the buddy memory allocation algorithm. Custom slab allocation functions are no longer needed since the only user was the kentry area, which has been removed recently. The KMEM_CACHE_NOCPUPOOL flag is also no longer needed since CPU pools, which are allocated from a kmem cache, can now always be allocated out of the direct physical mapping.

device: use general lock for port lists

2015-08-15T10:43:26Z

* device/if_hdr.h (struct ifnet): Turn the port list locks into general locks. (port_list_{lock_init,lock,unlock): New macros. * device/net_io.c (net_filter, net_set_filter): Use new macros. * device/subrs.c (if_init_queues): Likewise.

device: use general lock for `mach_device'

2015-08-15T10:43:26Z

* device/dev_hdr.h (struct mach_device): Turn lock into a general lock. (device_lock_init): New macro. (device_lock, device_unlock): Adapt accordingly. * device/dev_lookup.c (device_lookup): Use `device_lock_init'. * device/ds_routines.c (device_open): Adapt accordingly.

yyy more general locks, crashes, maybe b/c interrupt handler

kern: make sure the queue macros are only used on queues

2015-07-11T11:38:45Z

This turns mistakes as the one corrected in e59f05e9 into compile-time errors. * kern/queue.h: Add a new macro, queue_assert, and use it to assert that all arguments given to the queue macros have the correct type. * device/net_io.c (ENQUEUE_DEAD): Adapt to the fact that `queue_next(q)' is no longer an lvalue.

i386: improve the immediate console

2015-06-28T10:55:30Z

Improve the immediate console to the point that it can be enabled and display e.g. assertion failures from very early on (i.e. from `c_boot_entry'). * device/cons.h (romgetc, romputc): New declarations. * i386/configfrag.ac: Add configuration variable. * i386/i386at/conf.c (dev_name_list): Add entry. * i386/i386at/cons_conf.c (constab): Add entry. * i386/i386at/immc.c: Add missing includes. (immc_cnprobe, immc_cninit, immc_cngetc, immc_romputc): New functions. (immc_cnputc): Fix signature, use virtual addresses. * i386/i386at/immc.h: New file. * i386/i386at/kd.c: Use `#if ENABLE_IMMEDIATE_CONSOLE'. * i386/i386at/kd.h (kd_setpos): Add missing declaration. * i386/i386at/model_dep.c (c_boot_entry): Install immediate console as early boot console.

kern: import `macros.h' from x15

2015-05-19T14:11:56Z

Import the macro definitions from the x15 kernel project, and replace all similar definitions littered all over the place with it. Importing this file will make importing code from the x15 kernel easier. We are already using the red-black tree implementation and the slab allocator from it, and we will import even more code in the near future. * kern/list.h: Do not define `structof', include `macros.h' instead. * kern/rbtree.h: Likewise. * kern/slab.c: Do not define `ARRAY_SIZE', include `macros.h' instead. * i386/grub/misc.h: Likewise. * i386/i386/xen.h: Do not define `barrier', include `macros.h' instead. * kern/macro_help.h: Delete file. Replaced by `macros.h'. * kern/macros.h: New file. * Makefrag.am (libkernel_a_SOURCES): Add new file, remove old file. * device/dev_master.h: Adopt accordingly. * device/io_req.h: Likewise. * device/net_io.h: Likewise. * i386/intel/read_fault.c: Likewise. * ipc/ipc_kmsg.h: Likewise. * ipc/ipc_mqueue.h: Likewise. * ipc/ipc_object.h: Likewise. * ipc/ipc_port.h: Likewise. * ipc/ipc_space.h: Likewise. * ipc/ipc_splay.c: Likewise. * ipc/ipc_splay.h: Likewise. * kern/assert.h: Likewise. * kern/ast.h: Likewise. * kern/pc_sample.h: Likewise. * kern/refcount.h: Likewise. * kern/sched.h: Likewise. * kern/sched_prim.c: Likewise. * kern/timer.c: Likewise. * kern/timer.h: Likewise. * vm/vm_fault.c: Likewise. * vm/vm_map.h: Likewise. * vm/vm_object.h: Likewise. * vm/vm_page.h: Likewise.

Fix warnings

2015-05-02T12:18:47Z

* device/ds_routines.c (device_open, ds_open_done, device_close, device_write, device_write_inband, ds_write_done, device_read, device_read_inband, ds_read_done, device_set_status, mach_device_get_status, device_set_filter, device_map, ds_no_senders): Convert from K&R declaration, fix type of `device' into void*.

Fix block_io_mmap prototype

2015-05-02T12:05:52Z

* device/blkio.c (block_io_mmap): Fix prototype of dummy function. * device/blkio.h (block_io_mmap): Likewise.

device: Fix typos in comments (found by codespell)
