Changes in XEN3

Changes in XEN3_DOM0 http://nxr.netbsd.org/rss/src/sys/arch/amd64/conf/XEN3_DOM0 en Copyright 2005 Java pchtemp: add a simple driver for intel pch thermal sensor tested on PCI_PRODUCT_INTEL_2HS_THERM, which was found on HP Z4 G4. although other variants look compatible, i have not actually tested them. (no hardware) dmesg: ``` [ 512.596379] pchtemp0 at pci0 dev 20 function 2: Intel PCH Temperature Sensor ``` envstat: ``` [pchtemp0] pchtemp0 temperature: 41.500 degC ``` enable in kernel configs where amdtemp is enabled. the man page is mostly copy-and-paste from amdtemp.4. /src/sys/arch/amd64/conf/XEN3_DOM0 - 1.208 Fri Feb 20 07:54:26 UTC 2026 yamt Update rge* comment to include soon-to-arrive preliminary support for RTL8127 /src/sys/arch/amd64/conf/XEN3_DOM0 - 1.207 Fri Nov 07 19:07:38 UTC 2025 pgoyette Add Realtek 8126 to comment for rge* /src/sys/arch/amd64/conf/XEN3_DOM0 - 1.206 Tue Oct 21 18:26:24 UTC 2025 pgoyette branches: 1.205.2; actually include "amd64/conf/XEN3_DOM0.local as intended Typoed in previous commit.

This means that one can't enable in GENERIC.local many devices that are commented out in GENERIC. E.g, vio9p* at virtio? i915drm* at drm? qat* at pci? dev ? function ? audio* at audiobus? Switch to including XEN3.local instead of GENERIC.local to have a common file for local XEN3 specific configuration. See https://mail-index.netbsd.org/tech-kern/2024/08/11/msg029672.html for the discussion.

There are various mailing list threads going back to 2004 where the usefulness of this driver is discussed, but the conclusion is that scanner software has all moved to using ugen(4) instead, and enabling this driver will not help you scan things. /src/sys/arch/amd64/conf/XEN3_DOM0 - 1.193 Tue Jun 29 10:22:34 UTC 2021 nia branches: 1.192.4; XEN3_DOM0: Approach GENERIC When processed to remove comments, blank lines, normalize whitespace, and sort/uniq (one line was previously duplicated), this file is identical to the previous version. It has been reorganized to reduce diffs to GENERIC, and many missing lines from GENERIC have been added but commented out. /src/sys/arch/amd64/conf/XEN3_DOM0 - 1.192 Fri Mar 05 20:30:56 UTC 2021 gdt XEN3_DOM0: Move closer to GENERIC (NFC) This is another step in making XEN3_DOM0 closer to GENERIC. It is just reordering lines, adding commented out lines, and adding a few comments. (Test-booted with no dmesg change.) This pass is showing cases where there are substantive and likely undesired changes (e.g., UFS_ACL is not defined in XEN3_DOM0). Often I added them but commented them out to preserve the NFC property of this commit. My plan is to finish the easy NFC stuff first before addressing functional changes. /src/sys/arch/amd64/conf/XEN3_DOM0 - 1.191 Thu Mar 04 16:02:10 UTC 2021 gdt XEN3_DOM0: Move closer to GENERIC (NFC) This commit reorders some lines, and brings in commented lines from GENERIC to reduce the diff. It also brings in two agp lines, commented out, and with a warning that they are intentionally omitted. /src/sys/arch/amd64/conf/XEN3_DOM0 - 1.190 Wed Mar 03 00:31:19 UTC 2021 gdt XEN3_DOM0: Fix pckbc console attachment logic Copy PCKBD_CNATTACH_MAY_FAIL lines from GENERIC to XEN3_DOM0. GENERIC defines PCKBD_CNATTACH_MAY_FAIL, which means that an attempt to activate console input on pckbc will fail if there is no keyboard present. This is a problem on semi-modern machines that have pckbc silicon but not ports, and thus almost always have a USB keyboard also. What I suspect are bugs in console attachment logic lead to attempting to attach a ukbd while there already is a console keyboard, and with DIAGNOSTIC this is (properly) fatal, so XEN3_DOM0 blows up with a USB keyboard in current, and probably not in 9. Live tested on a machine that previously paniced on boot. /src/sys/arch/amd64/conf/XEN3_DOM0 - 1.189 Tue Mar 02 18:10:31 UTC 2021 gdt
