Annotation of wikisrc/laptops.mdwn, revision 1.33
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:
1.33 ! 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
1.33 ! nia 97: support for various ThinkPad-specific sensors and function keys.
1.6 jruoho 98:
1.33 ! nia 99: A number of NetBSD developers use ThinkPads to hack on NetBSD
1.21 nia 100: and for everyday usage.

103:
104: Installled with Coreboot and TianoCore (UEFI) firmware.
105:
1.33 ! nia 106: Destroy the GPT data with `gpt destroy wd0` before installing to the entire disk.
1.32 wiki 107:

1.33 ! nia 132: ## ThinkPad X220
1.17 nia 133:
134: * Video acceleration works, but when using `xf86-video-intel` (the default),
135: it's advisable to set `Option "AccelMethod" "uxa"` in `xorg.conf`.

1.20 nia 211: # PINE64
1.14 ryoon 212:
1.21 nia 213: A number of NetBSD developers use Pinebooks to hack on NetBSD
214: and for everyday usage.
215:
216: Pinebook and Pinebook Pro do not use ACPI, so certain aspects are
217: different compared to x86 laptops.
218:
1.20 nia 219: ## Pinebook (Allwinner A64)
1.14 ryoon 220:
1.28 nia 221: * Support for the display and HDMI output is provided through the Allwinner Display Engine driver.
222: This provides kernel modesetting and a full-resolution video framebuffer, however,
1.30 nia 223: the 3D acceleration features of the GPU are not yet accessible - Mesa llvmpipe is used instead.
1.28 nia 224: * The CPU frequency can be adjusted automatically with `estd` or with `sysctl machdep.cpufreq.*`.
1.20 nia 225: * [[!template id=man name="uvideo" section="4"]] webcam works.
226: * External WiFI adapters can be used. Support for the internal WiFi - after WiFi system rework?
1.1 reed 227:
1.26 nia 228: ## Pinebook Pro (Rockchip RK3399)
1.3 reed 229:
1.28 nia 230: * Support for the display output is provided through the Rockchip DRM driver.
231: This provides kernel modesetting and a full-resolution video framebuffer, however,
1.30 nia 232: the 3D acceleration features of the GPU are not yet accessible - Mesa llvmpipe is used instead.
1.28 nia 233: Currently, you can't connect external displays through USB-C.
234: * The CPU frequency can be adjusted automatically with `estd` or with `sysctl machdep.cpufreq.*`.
1.20 nia 235: * [[!template id=man name="uvideo" section="4"]] webcam works.
1.28 nia 236: * External WiFI adapters can be used. Support for the internal WiFi - after WiFi system rework?
237: Internal Broadcom WiFi is supported via the [[!template id=man name="bwfm" section="4"]] driver in -current.
238: However, external adapters may still be more stable.
1.20 nia 239: * The display backlight can be adjusted with `sysctl`.
1.26 nia 240:
241: ### Pinebook Pro CPU affinity
242:
243: After setting `security.models.extensions.user_set_cpu_affinity=1` in `/etc/sysctl.conf`,
244: you can run an intensive command on only the "big" CPUs:
245:
246: `$ schedctl -A 4,5 make package`
