sys_umap now supports only:
- looking up the physical address of a virtual address in the address space
of the caller;
- looking up the physical address of a grant for which the caller is the
grantee.
This is enough for nearly all umap users. The new sys_umap_remote supports
lookups in arbitrary address spaces and grants for arbitrary grantees.
and minor fixes:
. add ack/clean target to lib, 'unify' clean target
. add includes as library dependency
. mk: exclude warning options clang doesn't have in non-gcc
. set -e in lib/*.sh build files
. clang compile error circumvention (disable NOASSERTS for release builds)
A sort of quick hack for dhcpd to work as a client with lwip server.
- The functionality is not changed unless --lwip switch is supplied.
dhcpd does not use broadcast udp sockets but some sort of raw
sockets and changes their behavior during their life by ioctls.
- I thought there is no need to polute lwip just to make dhcp client
work. Instead I decided to twist the client a little bit.
- It is so far the only big collision I found between inet and lwip.
pkgsrc binary packages.
rationale:
. pkg_install (which is the pkg_* tools) is entangled with pkgsrc,
not with minix, so tracking it from pkgsrc (easier than with
base system) makes more sense
. simplifies upstreaming minix specific changes for pkg_* tools
. reduce pkgsrc-in-basesystem maintenance burden
- profile --nmi | --rtc sets the profiling mode
- --rtc is default, uses BIOS RTC, cannot profile kernel the presetted
frequency values apply
- --nmi is only available in APIC mode as it uses the NMI watchdog, -f
allows any frequency in Hz
- both modes use compatible data structures
- when kernel profiles a process for the first time it saves an entry
describing the process [endpoint|name]
- every profile sample is only [endpoint|pc]
- profile utility creates a table of endpoint <-> name relations and
translates endpoints of samples into names and writing out the
results to comply with the processing tools
- "task" endpoints like KERNEL are negative thus we must cast it to
unsigned when hashing
- contributed by Bjorn Swift
- adds process accounting, for example counting the number of messages
sent, how often the process was preemted and how much time it spent
in the run queue. These statistics, along with the current cpu load,
are sent back to the user-space scheduler in the Out Of Quantum
message.
- the user-space scheduler may choose to make use of these statistics
when making scheduling decisions. For isntance the cpu load becomes
especially useful when scheduling on multiple cores.
