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).
