Annotation of wikisrc/laptops.mdwn, revision 1.31
1.2 reed 1: This page lists and links to pages about laptops, notebooks,
1.20 nia 2: and portable computers that work well with NetBSD, are of interest
3: to developers, and are standardized or easy to find.
1.1 reed 4:
1.31 ! nia 5: This page references lots of different device drivers. All of them
! 6: are built-in to GENERIC kernels and you don't need to load them.

1.20 nia 12: # Generic laptop support
1.3 reed 13:
1.20 nia 14: ## Graphics
1.3 reed 15:
1.20 nia 16: NetBSD 9.0 supports Intel integrated graphics up to Kaby Lake,
17: Nvidia graphics up to Maxwell, and AMD graphics up to GCNv1.
1.3 reed 18:
1.20 nia 19: Anything newer than this will work, but will use `llvmpipe`
20: instead of hardware acceleration for OpenGL.
1.9 reed 21:
1.21 nia 22: The support includes connecting external monitors over HDMI,
23: DisplayPort, and DisplayPort over USB-C.
24:
25: For the Intel driver, there may be slight graphical corruptions
26: when using X11 without a compositor. Xfce/MATE include their own
27: compositors, but lightweight window managers can benefit from
28: having `picom` running.
29:
1.20 nia 30: ## CPU frequency adjustment
1.9 reed 31:
1.20 nia 32: On most ACPI and some non-ACPI laptops, the `sysutils/estd` package
33: can be used to automatically adjust the CPU frequency depending on
34: system load, and potentially prolong battery life. This modifies the
35: `frequency` variables exposed by
36: [[!template id=man name="sysctl" section="8"]].
1.9 reed 37:
1.20 nia 38: ## Suspend
1.13 ryoon 39:
1.20 nia 40: On ACPI systems, suspend-to-RAM is supported through
41: `sysctl hw.acpi.sleep.state=3`. This can be triggered through various
42: events (such as lid close) with
43: [[!template id=man name="powerd" section="8"]].
1.13 ryoon 44:
1.20 nia 45: Suspend on NetBSD currently seems to work best on Thinkpads.
1.13 ryoon 46:
1.20 nia 47: ## Input
1.13 ryoon 48:
1.20 nia 49: Many x86 laptops use Synaptics touchpads over an emulated PS/2 interface,
50: which is supported through [[!template id=man name="pms" section="4"]],
1.21 nia 51: with various adjustable Synaptics-specific sysctl variables.
1.9 reed 52:
1.20 nia 53: ## WiFi
1.1 reed 54:
1.20 nia 55: Many x86 laptops with Intel processors will have WiFi cards supported
56: by the
57: [[!template id=man name="iwm" section="4"]] driver, or
58: [[!template id=man name="iwn" section="4"]] for older models.
59: Atheros 11n miniPCIe cards are supported by the
60: [[!template id=man name="athn" section="4"]] driver.
1.1 reed 61:
1.20 nia 62: See the
63: [[!template id=man name="afterboot" section="8"]] man page for details
1.24 nia 64: on connecting to WiFi networks.
1.1 reed 65:
1.21 nia 66: USB 11n WiFi adapters such as
1.20 nia 67: [[!template id=man name="urtwn" section="4"]] and
68: [[!template id=man name="run" section="4"]] can also be used,
69: and most/all generic USB ethernet adapters are also well supported.
70: For a fairly complete list, see
71: [[!template id=man name="usb" section="4"]].
1.3 reed 72:
1.21 nia 73: Unfortunately, WiFi hardware is not particularly standardized compared
74: to most other aspects of modern laptops.
75:
1.20 nia 76: ## Audio
1.11 reed 77:
1.21 nia 78: Essentially all modern x86 laptops use the
1.20 nia 79: [[!template id=man name="hdaudio" section="4"]] driver.
1.11 reed 80:
1.20 nia 81: In the case that switching between speakers and the headphone port
82: is not handled automatically by the hardware, the `dacsel`
83: [[!template id=man name="mixerctl" section="1"]] variable can be
84: modified.
1.11 reed 85:
1.22 nia 86: ## Sensors
87:
88: Regardless of whether the system is ACPI, NetBSD will
89: expose all sensors (e.g. for temperature and battery)
90: via [[!template id=man name="envstat" section="8"]].
91:

1.20 nia 94: # IBM / Lenovo
1.9 reed 95:
1.20 nia 96: The [[!template id=man name="thinkpad" section="4"]] driver provides
97: support for various Thinkpad-specific sensors and function keys.
1.6 jruoho 98:
1.21 nia 99: A number of NetBSD developers use Thinkpads to hack on NetBSD
100: and for everyday usage.
101:
1.9 reed 102: ## ThinkPad T22
103:
104: Works perfect (sound, display, all devices, infrared port not tested).
105:
1.6 jruoho 106: ## ThinkPad X60s
107:
1.15 sevan 108: Everything works.
1.6 jruoho 109:
1.9 reed 110: ## ThinkPad X41
111:
112: Works fine (sound, display, all devices, bluetooth, modem not tested).
113:
1.6 jruoho 114: ## ThinkPad X61s
115:
116: Everything works. Requires `PCI_BUS_FIXUP` and `PCI_ADDR_FIXUP` [[!template
117: id=man name="options" section="4"]].
118:
1.17 nia 119: ## Thinkpad X220
120:
121: * Video acceleration works, but when using `xf86-video-intel` (the default),
122: it's advisable to set `Option "AccelMethod" "uxa"` in `xorg.conf`.
1.19 nia 123: * Ethernet is supported through the [[!template id=man name="wm" section="4"]] driver.
124: * WiFi is supported through the [[!template id=man name="iwn" section="4"]] driver.
1.17 nia 125: * Suspend and resume work.
126:
1.19 nia 127: ## Thinkpad X230

1.19 nia 130: * Ethernet is supported through the [[!template id=man name="wm" section="4"]] driver.
131: * WiFi is supported through the [[!template id=man name="iwn" section="4"]] driver.
132:
1.16 nia 133: ## Thinkpad X250
134:
1.28 nia 135: * Accelerated graphics.
136: * Connecting externals displays works with the miniDP and VGA ports.
1.19 nia 137: * SD card reader is supported through the [[!template id=man name="rtsx" section="4"]] driver.
138: * Ethernet is supported through the [[!template id=man name="wm" section="4"]] driver.
139: * WiFi is supported through the [[!template id=man name="iwm" section="4"]] driver.
1.27 nia 140: * Extra trackpoint buttons: run at least 9.0_STABLE for fixes to the Synaptics driver.
141: * Brightness buttons do not work in 9.0 by default. You can bind them to
1.16 nia 142: xrandr in your window manager.
1.19 nia 143: * Webcam will depend on upcoming xhci isochronous pipe support.
144: * To record from the internal mic, set `mixerctl -w record.source=ADC02`
1.27 nia 145: * Some spam from [[!template id=man name="hdaudio" section="4"]] on some
146: reboots, the chip doesn't seem to reset properly. Disappears and boots
147: normally after a few seconds.
148: [[!template id=pr number=51734]]
1.23 nia 149: * Suspend and resume work.
1.16 nia 150:

1.20 nia 198: # PINE64
1.14 ryoon 199:
1.21 nia 200: A number of NetBSD developers use Pinebooks to hack on NetBSD
201: and for everyday usage.
202:
203: Pinebook and Pinebook Pro do not use ACPI, so certain aspects are
204: different compared to x86 laptops.
205:
1.20 nia 206: ## Pinebook (Allwinner A64)
1.14 ryoon 207:
1.28 nia 208: * Support for the display and HDMI output is provided through the Allwinner Display Engine driver.
209: This provides kernel modesetting and a full-resolution video framebuffer, however,
1.30 nia 210: the 3D acceleration features of the GPU are not yet accessible - Mesa llvmpipe is used instead.
1.28 nia 211: * The CPU frequency can be adjusted automatically with `estd` or with `sysctl machdep.cpufreq.*`.
1.20 nia 212: * [[!template id=man name="uvideo" section="4"]] webcam works.
213: * External WiFI adapters can be used. Support for the internal WiFi - after WiFi system rework?
1.1 reed 214:
1.26 nia 215: ## Pinebook Pro (Rockchip RK3399)
1.3 reed 216:
1.28 nia 217: * Support for the display output is provided through the Rockchip DRM driver.
218: This provides kernel modesetting and a full-resolution video framebuffer, however,
1.30 nia 219: the 3D acceleration features of the GPU are not yet accessible - Mesa llvmpipe is used instead.
1.28 nia 220: Currently, you can't connect external displays through USB-C.
221: * The CPU frequency can be adjusted automatically with `estd` or with `sysctl machdep.cpufreq.*`.
1.20 nia 222: * [[!template id=man name="uvideo" section="4"]] webcam works.
1.28 nia 223: * External WiFI adapters can be used. Support for the internal WiFi - after WiFi system rework?
224: Internal Broadcom WiFi is supported via the [[!template id=man name="bwfm" section="4"]] driver in -current.
225: However, external adapters may still be more stable.
1.20 nia 226: * The display backlight can be adjusted with `sysctl`.
1.26 nia 227:
228: ### Pinebook Pro CPU affinity
229:
230: After setting `security.models.extensions.user_set_cpu_affinity=1` in `/etc/sysctl.conf`,
231: you can run an intensive command on only the "big" CPUs:
232:
233: `$ schedctl -A 4,5 make package`
