cinap_lenrek 5ea540e75d sdiahci: enable pci busmaster before ahciconfigdrive() (fix qemu crash) 
enable pci busmaster before set the fis-receive-enable
bit in the port command register.

not doing so triggers a crash in qemu like:

address_space_unmap: Assertion `mr != NULL' failed.

as qemu tries to process the dma command list as soon
as we set that flag and busmaster dma needs to be enabled
at this point.

cinap_lenrek fc0f08c651 pc, pc64: make sure write combining is supported in MTRR's before setting it 2020-12-11 15:23:03 +01:00
cinap_lenrek 658c994cff pc, pc64: ignore MTRR's when MTRRCap.vcnt and MTRRCap.fix are zero 
Bhyve returns 0 in MTRRCap register, so we
can use that instead on relying on cpuid only
to see if MTRR's are supported.

That way we can get rid of the sanity check
in memory.c.

cinap_lenrek eb3d055eb3 backout OCEXEC changes when potentially opening /srv files 
Opening a /srv file sets the close-on-exec flag on the
shared channel breaking the exportfs openmount() hack.

The devsrv tries to prevent posting a channel with the
close-on-exec or remove-on-close flags. but nothing
currently prevents this poisoning on open.

Until this gets fixed in eigther exportfs or devsrv,
i'll back out the changes that could have potential side
effects like this.

cinap_lenrek 263dc8093d pc64: preserve reserved bits in CR0/CR4 for amd64 in mtrr setstate() 
On AMD64, CR0/CR4 are 64-bit registers, with
the upper half reserved. So use uintptr type
to store the register values to get 32 bit on 386
and 64 bit on AMD64.

cinap_lenrek c74458c98b vmx: add -v|-w flag to control window creation behaviour 
The -v flag now does not create a new rio window,
while -w flag does (restores the old behaviour).

This allows vmx to run under vncs and is in general
mode aligned to other emulators and programs.

kvik a92ffdbbfb libndb: remove db file size limit 
Removes the 128 kB limit for files making up the database.
We used to skip over and complain about files that exceeded
the limit, forcing the user to generate hash files.

This caused things to inexplicably stop working after a file
hit the hidden limit, which is unreasonable behaviour considering
that libndb happily, albeit slowly, works with bigger files.
