when we hit a conflict where the pci INTL register gives us
a different irq than we get from southbridge irq router, dont
just change the router setting to the bios assigned irq (that
was previously known as the BIOS workarround), but assume the
southbridge setting to be valid and change the pci INTL register
on the device to it.
only when the router link doesnt seem to be configured or
disabled, then program the router to the irq that bios asisgned
in the INTL register.
the reason is that changing the router setting changes the
irq routing for *all* devices on the same link and changing
it breaks previously checked and valid interrupt routings.
(so happend with virtualbox where the last device on the bus
is some powermanagement device that has wrong INTL setting
and changing the routing breaks the ethernet interrupts)
this change shouldnt affect modern machines which use ioapic
and mp tables or acpi for pci interrupt routing.

we add new function convmemsize() that returns the size of
*usable* conventional memory that does some sanity checking
and reserves the last KB below the top of memory pointer.
this avoids lowraminit() overriding potential bios tables
and sigsearch() going off the rails looking for tables
at above 640K.

do the message drawing from the screenproc so there are no
race conditions with libdraw.

the x200s is too slow on a single core to keep up without
audio buffer underruns, so the idea is to flush screen
in parallel to witing audio samples in a separate process.
with the proc, we also can keep updating the screen on resize
when paused.

sed just continued writing past genbuf when it should stop
with "Output line too long".
quit when we get unspecified options.
stupid casts from long to char* for no reason.
some 0 vs nil cleanup.

depending on kernel size)
we now do mapping of KZERO to ROUND(end, 4*MB) where
end needs not to be above 16MB. this allows for bigger
kernels.
|
|
traditionally, the pc kernel mapped the first 8MB of physical
address space. when the kernel size grows beyond that memory mapping,
it will crash on boot and theres no checking in the build process
making sure it fits.
with the pc64 kernel, it is not hard to always map the whole
kernel memory image from KZERO to end[], so that the kernel will
always fit into the initial mapping.

we can improve performance alot by using webfs which
does http keep alives for us, so connection setup
overhead is eleminated.
fix 9p flushes and double frees.

this is a good example of why blindly copy-pasting patches is a bad idea.
|
|
procctl() is always called with up and it would not
work correctly if passed a different process, so
remove the Proc* argument and use up directly.
|
|
we can avoid some flickering when removing the software cursor
from the shadow framebuffer by avoiding the flushscreenimage()
call.
once the cursor is redrawn, we flush the combined rect of its
old and new position in one go.
|
|
theres no point in doing domain checks on literal ip addresses,
so handle that case early.

werrstr() takes a format string as its first argument.
a common error is to pass user controlled string buffers
into werrstr() that might contain format string escapes
causing werrstr() to take bogus arguments from the stack
and crash.
so instead of doing:
werrstr(buf);
we want todo:
werrstr("%s", buf);
or if we have a local ERRMAX sized buffer that we can override:
errstr(buf, sizeof buf);
|
|
this fixes a potential format string problem where the
error string is passed to werrstr() as fmt. also, the
directory comparsion is simplified in this version using
a helper function.
