This patch introduces a framebuffer to Minix. It's written for the ARM
port of Minix, but has an architectural split that separates the
hardware dependent part from the non-hardware dependent part. Futhermore,
this driver was developed using a screen that has a native resolution of
1024x600 pixels and having lack of support for obtaining EDID from the
screen. Consequently, it uses a hardcoded resolution of 1024x600.
The driver uses an interface based on the Linux ioctl API, but supports
only a very limited subset.
* Generalize GPIO handling.
* Add libs to configure gpio's clocks and pads
* Add Interrupt handling.
* Introduce mmio.h and log.h
Change-Id: I928e4c807d15031de2eede4b3ecff62df795f8ac
* let busy loops timeout.
* Start using interrupt handlers.
* Allocate the ramdisk only when used.

Also did some cleanup in ash sources, to make minix modifications
more obvious, as well as some simplifications (by removing code which
is never compiled)
Removed EDITLINE support, use libedit, which does the termcap/terminfo
handling.

Small GPIO driver that exports a few pins using a virtual file
system. Currently the two user leds and the user button are exported.

The way etcfiles was re-implemented was wrong as it would overwrite the
password database. This patch adds back a proper etcfiles (safe) target,
and a etcforce (unsafe) target.

With the build system upgrade, the list of system directories was
recreated, and the sticky bit was forgotten.

* Remade patch so it works with minix patch tool.
* New MINIX tar support -ox, so revert back to it
In fetch scripts, tar had been replaced by bsdtar as the prebvious
tar did not support the -o flag under minix, which is required to
prevent usage of tar file stored user and group information.
This introduces portability problems. As our new tar tool now
support that flag revert back to improve portability.
upgrade to NetBSD CVS release from 2012/10/17 12:00:00 UTC
Makefiles updates to imporve portability
Made sure to be consistent in the usage of braces/parenthesis at
least on a per file basis. For variables, it is recommended to
continue to use braces.
The tested targets are the followgin ones:
* tools
* distribution
* sets
* release
The remaining NetBSD targets have not been disabled nor tested
*at all*. Try them at your own risk, they may reboot the earth.
For all compliant Makefiles, objects and generated files are put in
MAKEOBJDIR, which means you can now keep objects between two branch
switching. Same for DESTDIR, please refer to build.sh options.
Regarding new or modifications of Makefiles a few things:
* Read share/mk/bsd.README
* If you add a subdirectory, add a Makefile in it, and have it called
by the parent through the SUBDIR variable.
* Do not add arbitrary inclusion which crosses to another branch of
the hierarchy; If you can't do without it, put a comment on why.
If possible, do not use inclusion at all.
* Use as much as possible the infrastructure, it is here to make
life easier, do not fight it.
Sets and package are now used to track files.
We have one set called "minix", composed of one package called "minix-sys"
Bumping libc files for unsupported architectures, to simplify merging.
A bunch of small fixes:
* in libutil update
* the macro in endian.h
* some undefined types due to clear separation from host.
* Fix a warning for cdbr.c
Some modification which were required for the new build system:
* inclusion path for const.h in sconst, still hacky
* Removed default malloc.c which conflicts on some occasions.
- inherit a predefined set of system environment variables
(the current set of inherited variables is: ahci; acpi; no_apic);
- auto-adjust the default menu option when lines are auto-removed;
- add variable substitution support for /etc/boot.cfg.local;
- make default menu options in boot.cfg.local relative to itself,
allowing one to set the default to a menu option from this file.
- add "edit" menu option, to edit menu commands before executing them;
- add "menu" boot command, to return to the menu from the prompt;
- provide more line editing features when getting input;
- fix a few potential buffer overflows as a side effect.
complete munmap implementation; single-page references made
a general munmap() implementation possible to write cleanly.
. memory: let the MIOCRAMSIZE ioctl set the imgrd device
size (but only to 0)
. let the ramdisk command set sizes to 0
. use this command to set /dev/imgrd to 0 after mounting /usr
in /etc/rc, so the boot time ramdisk is freed (about 4MB
currently)
The rc script manually parses /etc/fstab to mount all file systems.
To do that it needs /bin/sed which does not exist anymore. mount(8)
now supports the -a flag which causes it to mount all file systems
listed in /etc/fstab except for '/'. File systems marked with 'noauto'
are skipped.
Adding hot plugging infrastructure in rc file. This includes
starting the devman service, mounting it's file system and
starting the corresponding devmand daemon.
This patch also provide error free shutdown of the USB sub-system.
The USB sub system needs to be shutdown in a certain order but also
consists of components living in /usr/pkg/. By checking the
existence of usbd we can stop it in the correct order.
. new mode for sys_memset: include process so memset can be
done in physical or virtual address space.
. add a mode to mmap() that lets a process allocate uninitialized
memory.
. this allows an exec()er (RS, VFS, etc.) to request uninitialized
memory from VM and selectively clear the ranges that don't come
from a file, leaving no uninitialized memory left for the process
to see.
. use callbacks for clearing the process, clearing memory in the
process, and copying into the process; so that the libexec code
can be used from rs, vfs, and in the future, kernel (to load vm)
and vm (to load boot-time processes)
these two functions will be used to support all exec() functionality
going into a single library shared by RS and VFS and exec() knowledge
leaving VM.
. third-party mmap: allow certain processes (VFS, RS) to
do mmap() on behalf of another process
. PROCCTL: used to free and clear a process' address space
. readbios call is now a physical copy with range check in
the kernel call instead of BIOS_SEG+umap_bios
. requires all access to physical memory in bios range to go
through sys_readbios
. drivers/dpeth: wasn't using it
. adjusted printer
building defaults to off until clang is updated.
current clang does not handle -shared, necessary to change the ld
invocation to build shared libraries properly. a new clang should be
installed and MKPIC defaults to no unless the newer clang is detected.
changes:
. mainly small imports of a Makefile or two and small fixes
(turning things back on that were turned off in Makefiles)
. e.g.: dynamic librefuse now depends on dynamic
libpuffs, so libpuffs has to be built dynamically too
and a make dependency barrier is needed in lib/Makefile
. all library objects now have a PIC (for .so) and non-PIC
version, so everything is built twice.
. generate PIC versions of the compat (un-RENAMEd) jump files,
include function type annotation in generated assembly
. build progs with -static by default for now
. also build ld.elf_so
. also import NetBSD ldd
