| * Fix object construction in the slab allocatorRichard Braun2013-06-091-4/+10
| | | | | | | | | | | | | | | | There is currently no actual use of constructors, which is why this bug has been long overlooked. * kern/slab.c (kmem_cpu_pool_fill): Call constructor on buffers unless verification is enabled for the cache, or the constructor is NULL.
* | Do not skip AHCI controller without HOST_CAP_ONLYSamuel Thibault2013-06-091-4/+0
| | | | | | | | | | | | | | | | We rather rely on the announced PCI type to determine whether to use IDE or AHCI. * linux/dev/drivers/block/ahci.c (ahci_probe_dev): Do not skip AHCI controller without HOST_CAP_ONLY.

(ahci_do_port_request): When `lba48' is true, use WIN_READDMA_EXT and WIN_WRITEDMA_EXT commands. (ahci_probe_port): Test lba48 flag, read capacity and set `lba48' accordingly. Display size in GiB above 10GiB. * linux/src/include/linux/hdreg.h (WIN_READDMA_EXT, WIN_WRITEDMA_EXT): New macros (hd_driveid): Add `command_set_2' and lba_capacity_2' fields.

* Remove duplicate lineSamuel Thibault2013-05-191-1/+0
| | | | | | | Reported by Miguel Figueiredo * kern/thread.c (thread_create): Remove duplicate reset of new_thread->pc_sample.buffer to 0.
* Reduce fragmentation in the slab allocatorRichard Braun2013-05-161-2/+5
| | | | | | | | | | This reverts a change brought when reworking slab lists handling that made the allocator store slabs in LIFO order, whatever their reference count. While it's fine for free slabs, it actually increased fragmentation for partial slabs. * kern/slab.c (kmem_cache_alloc_from_slab): Insert slabs that become partial at the end of the partial slabs list.

| | | | | * linux/dev/drivers/block/ahci.c (ahci_probe_dev): Add missing parameters to printf.
* Fix ahci.h pathSamuel Thibault2013-05-101-1/+1
| | | | * linux/Makefrag.am (liblinux_a_SOURCES): Fix path to ahci.h

(probe_for_hwifs): Call ahci_probe_pci.
* Fix non-block-aligned-offset readsSamuel Thibault2013-05-021-2/+2
| | | | | | | | This fixes grave issues when device_read is called with non-block-aligned offset, e.g. when using grub-probe with a non-block-aligned partition table. * linux/dev/glue/block.c (rdwr_full): Use current position instead of base buffer position to check for alignment.

| * Optimize slab reapingRichard Braun2013-04-211-13/+10
| | | | | | | | | | | | | | | | Instead of walking the list of free slabs while holding the cache lock, detach the list from the cache and directly compute the final count values, and destroy slabs after releasing the cache lock. * kern/slab.c (kmem_cache_reap): Optimize.
| * Rework slab lists handlingRichard Braun2013-04-212-81/+8
| | | | | | | | | | | | | | | | | | | | | | | | Don't enforce strong ordering of partial slabs. Separating partial slabs from free slabs is already effective against fragmentation, and sorting would sometimes cause pathological scalability issues. In addition, store new slabs (whether free or partial) in LIFO order for better cache usage. * kern/slab.c (kmem_cache_grow): Insert new slab at the head of the slabs list. (kmem_cache_alloc_from_slab): Likewise. In addition, don't sort partial slabs. (kmem_cache_free_to_slab): Likewise. * kern/slab.h: Remove comment about partial slabs sorting.
| * Fix locking error in the slab allocatorRichard Braun2013-04-211-0/+2
| | | | | | | | | | * kern/slab.c (kmem_cache_free): Lock cache before releasing an object to the slab layer.
* | Fix macro nameSamuel Thibault2013-05-011-1/+1
|/ | | | | | * linux/dev/glue/block.c (device_get_status): Use DEV_GET_RECORDS_RECORD_SIZE for DEV_GET_RECORDS instead of DEV_GET_SIZE_RECORD_SIZE.
* Add -fno-optimize-sibling-calls option for better kdb tracesSamuel Thibault2013-04-081-1/+1
| | | | | * Makefrag.am (AM_CFLAGS) [enable_kdb]: Add -fno-optimize-sibling-calls option.
* Update BASEPRI_USERSamuel Thibault2013-03-111-1/+1
| | | | * kern/sched.h (BASEPRI_USER): Increase to 25.
* Fix build without kdbSamuel Thibault2013-03-111-0/+2
| | | | | * i386/i386/db_interface.h [! MACH_KBD] (db_set_hw_watchpoint, db_clear_hw_watchpoint, db_dr): Do not declare functions.
* Increase number of prioritiesSamuel Thibault2013-03-061-1/+1
| | | | * kern/sched.h (NRQS): Increase to 50.
* Do not hardcode maximum priority valueSamuel Thibault2013-03-051-5/+5
| | | | | * kern/sched_prim.c (do_priority_computation): Replace 31 with NRQS - 1. idle_thread: Likewise.
* Include machine/db_interface instead of hardcoding function prototypesSamuel Thibault2013-02-042-8/+4
| | | | | | | | | * ddb/db_access.c: Include <machine/db_interface.h>. (db_read_bytes, db_write_bytes): Remove functions prototypes. (db_get_task_value): Fix calling db_read_bytes.
