2017-05-08add a BUS_DMA_64BIT flag to bus_dma on all our archs.David Gwynne
this is so drivers can advertise that they can handle 64 dma addresses to the platform. it may choose to handle dmamaps differently based on this flag. tweaks and ok tom@ ok kettenis@

2017-02-12Split up fork1():Philip Guenther
- FORK_THREAD handling is a totally separate function, thread_fork(), that is only used by sys___tfork() and which loses the flags, func, arg, and newprocp parameters and gains tcb parameter to guarantee the new thread's TCB is set before the creating thread returns - fork1() loses its stack and tidptr parameters Common bits factor out: - struct proc allocation and initialization moves to thread_new() - maxthread handling moves to fork_check_maxthread() - setting the new thread running moves to fork_thread_start() The MD cpu_fork() function swaps its unused stacksize parameter for a tcb parameter. luna88k testing by aoyama@, alpha testing by dlg@ ok mpi@

2017-02-08In exec_elf.c: expand ELFNAME(), ELFNAME2(), and ELFNAMEEND() exceptPhilip Guenther
leaving out the size, so that ELFNAME2(exec,makecmds) becomes exec_elf_makecmds instead of exec_elf{32,64}_makecmds and then delete the ELFNAME2() and ELFNAMEEND() macros. Move the prototypes for functions local to exec_elf.c to there from exec_elf.h. Simplify the SMALL_KERNEL conditionals around the ELF coredump code. Change exec_conf.c to use the size-generic names and macros Remove exec_elf{32,64}.c and just build exec_elf.c; delete the _KERN_DO_ELF and _KERN_DO_ELF64 #defines. ok jca@, encouragement from deraadt@ and tom@
2017-01-22Introduce the KEEPKERNELS variable: if this is set either in mk.conf orTheo Buehler
the environment, 'make cleandir' does not descend into kernel build directories. Thus, kernel object files survive 'make build' on slower architectures. WARNING: If you set this variable, you run the risk of breaking 'make release': Be sure to run 'make cleandir' from /sys/arch/$(machine)/compile before doing 'make release'. This issue will be addressed shortly. requested by kettenis; ok deraadt

2016-11-29Build kernel with DEBUG=-g by default.Martin Pieuchot
This will allow us to extract type informations from DWARF2 sections. It also makes developer life easier as debug information are now included in every object. Resulting kernels will be stripped using strip(1) instead of ld(1). Kernel build time increases by approximately 10%. However it is still possible to disable this by defining DEBUG="". ok kettenis@, bluhm@, natano@, jasper@, reyk@, deraadt@
2016-11-15Clean up the kernel Makefile's:Martin Natano
- Remove the 'lint' target. lint has been removed with OpenBSD 5.2. - Remove the 'tags' target. It does nothing of value. - Replace 'clean::' with 'clean:', as requested by espie and millert, and remove files from the 'clean' target, that are never generated. - Don't create a file called 'depend' in 'make depend', but just do nothing instead. ok mpi tb

2016-11-05Two tweaks for compile/Makefile.inc:Martin Natano
1) Replace '.elif !exists(${OBJDIR}/Makefile)' with just '.else'. espie pointed out, that if the file existed, make wouldn't be reading this file, so the check is superflous. Less clutter. 2) Unconditionally define the 'clean' and 'cleandir' targets, also when obj doesn't exist. This changes the behaviour of 'make clean' to be successful (doing nothing) without obj@ or obj/. ok tb millert deraadt

2016-10-15cleandir: target for kernel compile directoriesTheo de Raadt
ok natano
2016-10-14Kernel builds now happen in compile/CONFIG/obj@ -> /usr/obj/... [or ./obj/,Theo de Raadt
if srctree is not rooted at /usr/src]. As a result, stock GENERIC & RAMDISK kernels are commited to the tree, to ensure the src tree can be "readonly" during builds, with all writes occuring inside the obj space. config -b options are handled by ../Makefile.inc. The canonical new way to configure one of these kernels is: % cd /sys/arch/amd64/compile/GENERIC.MP % doas make obj % make config % make % doas cp obj/bsd /bsd The build infrastructure will use this new mechanism in a de-escalation way using BUILDUSER. Much help from natano and tb.

2016-09-25Make a move towards ending 4 decades of kernel snooping.Theo de Raadt
Add sysctl kern.allowkmem (default 0) which controls the ability to open /dev/mem or /dev/kmem at securelevel > 0. Over 15 years we converted 99% of utilities in the tree to operate on sysctl-nodes (either by themselves or via code hiding in the guts of -lkvm). pstat -d and -v & procmap are affected and continued use of them will require kern.allowkmem=1 in /etc/sysctl.conf. acpidump (and it's buddy sendbug) are affected, but we'll work out a solution soon. There will be some impact in ports. ok kettenis guenther

2016-09-15all pools have their ipl set via pool_setipl, so fold it into pool_init.David Gwynne
the ioff argument to pool_init() is unused and has been for many years, so this replaces it with an ipl argument. because the ipl will be set on init we no longer need pool_setipl. most of these changes have been done with coccinelle using the spatch below. cocci sucks at formatting code though, so i fixed that by hand. the manpage and subr_pool.c bits i did myself. ok tedu@ jmatthew@ @ipl@ expression pp; expression ipl; expression s, a, o, f, m, p; @@ -pool_init(pp, s, a, o, f, m, p); -pool_setipl(pp, ipl); +pool_init(pp, s, a, ipl, f, m, p);
