provides support for hardware-accelerated virtualization on NetBSD.
It is made of an MI frontend, to which MD backends can be plugged. One
MD backend is implemented, x86-SVM, for x86 AMD CPUs.
We install
/usr/include/dev/nvmm/nvmm.h
/usr/include/dev/nvmm/nvmm_ioctl.h
/usr/include/dev/nvmm/{arch}/nvmm_{arch}.h
And the kernel module. For now, the only architecture where we do that
is amd64 (arch=x86).
NVMM is not enabled by default in amd64-GENERIC, but is instead easily
modloadable.
Sent to tech-kern@ a month ago. Validated with kASan, and optimized
with tprof.
ioctl was passed through ifioctl_common, because the case falls through
to the SIOCSIFFLAGS case. The common handler however doesn't implement
SIOCINITIFADDR, so an attempt to configure plip always failed with ENOTTY.
triggerring panic when disks are plugged to non-adjacent ports - this should
fix panic reported by Masanobu SAITOH on current-users
also fix different miscounting of ports in ahci_setup_ports() and
ahci_reprobe_drives()
on PCH2. wm_gate_hw_phy_config_ich8lan(true) is called in wm_reset(), so
wm_phy_post_reset(false) should be called after reset.
- On PCH2, set the phy config counter to 50msec after (PHY) reset.
When a wrong value is read when boot, the read device ID was incorrect and
ukphy(3) is attached instead of ihphy(4). The bug might also result in
MDIC read/write error.
How to reproduce:
0) Boot Windows.
1) Leave some minutes.
2) Reboot to NetBSD.
To fix this problem, adding extra 100us delay at the end of
wm_gmii_mdic_{read,write}reg() on PCH2. Same as FreeBSD and linux.
Reported by David Brownlee a few days ago and also reported by jmcneill
a half year ago. Tested with my own Thinkpad X220.

PCH_LPT with I218. Same as FreeBSD and Linux. This woraround is only for
device ID 0x155a, 0x15a2, 0x1559 and 0x15a3. I observed this problem on my
Shuttle DS57U's I218 port six times in two months.
(Excessive Collision) bit nor LC (Late Collision) bit (reserved).
Refer "PCIe GbE Controller Open Source Software Developer's Manual",
82574 datasheet and newer.
XXX I saw the LC bit was set on I218 even though the media was full duplex,
so the bit might be used for other meaning ...(I have no document).
- Use macro.
Recent u-boot starts up the watchdog timer, and we don't detect this so
e.g. my DE0 nanosoc reboots after about 20 seconds. Applying a reset to
the watchdog circuit is the only way to stop it according to the
documentation.
In-System Design ATA protocol over Bulk-Only devices from most kernels,
leave only in i386/amd64 ALL; it's unmaintained and likely currently broken,
lack of test hardware makes it impossible to support
