- preemption handled in the clock timer interrupt handler, not in the clock task
- more achitecture independent clock timer handling code
- smp ready as each CPU can have its own timer
- fixes a problem in inodes truct definitions. The original definitions use
posix types. These types don't have well defined size. Therefore when
compiling mkfs on a different system natively the inodes sizes do not match.
This patch replaces the posix types with interger types of the same size and
signedness as the original types in use.
- The primary reason is that mkfs and installboot need to run natively during
the cross compilation (host and target versions are compiled). There is a
collision of include files though. E.g. a.out.h is very minix-specific.
Therefore some files we moved and replaced by stubs that include the original
file if compiling on or for Minix :
include/a.out.h -> include/minix/a.out.h
include/sys/dir.h -> include/minix/dir.h
include/dirent.h -> include/minix/dirent.h
include/sys/types.h -> include/minix/types.h
- This does not break any native compilation on Minix. Other headers that were
including the original files are changed according to include directly the
new, minix specific location not to pick up the host system includes while
cross-compiling.
- role of this patch is to make rebasing of the build branch simpler until the
new build system is merged
- the PIC master and slave irq handlers don't pass the irq hook pointer but just
the irq number. It gives a little bit more information to the C handler as the
irq number is not lost
- the irq code path is more achitecture independent. i386 hw interrupts are
called irq and whereever the code is arch independent enough hw_intr_
functions are called to mask/unmask interrupts
- the legacy PIC is not the only possible interrupt controller in the x86 world,
therefore the intr_(un)mask functions were renamed to signal their
functionality explicitly. APIC will add their own.
- masking and unmasking PIC interrupt lines is removed from assembler and all
the functionality is rewriten in C and moved to i8259.c
- interrupt handlers have to unmask the interrupt line if all irq handlers are
done. Assembler does not do it anymore
told to kernel
- makes VM ask the kernel if a certain process is allowed
to map in a range of physical memory (VM rounds it to page
boundaries afterwards - but it's impossible to map anything
smaller otherwise so I assume this is safe, i.e. there won't
be anything else in that page; certainly no regular memory)
- VM permission check cleanup (no more hardcoded calls, less
hardcoded logic, more readable main loop), a loose end left
by GQ
- remove do_copy warning, as the ipc server triggers this but
it's no more harmful than the special cases already excluded
explicitly (VFS, PM, etc).
IS:
- do not use p_getfrom_e for a process that is sending
- register with TTY only function keys that are used
- various header and formatting fixes
- proper shutdown code
TTY:
- restore proper Ctrl+F1 dump contents
isofs:
- don't even try to call sys_exit()
- an asmconv based tool for conversion from GNU ia32 assembly to ACK assembly
- in contrast to asmconv it is a one way tool only
- as the GNU assembly in Minix does not prefix global C symbols with _ gas2ack
detects such symbols and prefixes them to be compliant with the ACK convention
- gas2ack preserves comments and unexpanded macros
- bunch of fixes to the asmconv GNU->ACK direction
- support of more instructions that ACK does not know but are in use in Minix
- it is meant as a temporary solution as long as ACK will be a supported
compiler for the core system
- MFS and mkfs(1) now perform extra sanity checks
- fsck(1) can now deal with inode tables extending beyond the file
system's first 4GB
- badblocks(8) no longer writes out the superblock for no reason
- mkfs(1) no longer crashes when given no parameters
- more(1) no longer crashes when standard output is redirected
that some hardware had
- clear DMA_ST_INT after DMA - fixes infinite number of interrupts
that some hardware had
- initial ATAPI DMA implementation, doesn't actually increase performance
on my test hardware so possibly not right yet, disabled by default
debugging info on panic: decode segment selectors and descriptors, now moved
to arch-specific part, prototypes added; sanity checking in debug.h made
optional with vmassert().
be used concurrently. pass the function in eax instead; this gets rid
of the global variable. also execute the function directly if we're
already trapped into the kernel.
revert of u32_t endpoint_t to int (some code assumes endpoints are
negative for negative slot numbers).
