Framework Laptop 13 AMD Ryzen 5 7640U

Device notes and configuration under Linux for the Framework Laptop 13 AMD Ryzen 7040 Series Ryzen 5 7640U variant, DIY edition.

Everything works of the box as of Linux v6.5 (>=6.9 recommended) with firmware version 03.03 (03.05 recommended).

Specs

• AMD Ryzen 7640U (Phoenix, Zen 4)
• SK hynix Platinum P41 1TB SSD
• Crucial CT2K16G56C46S5 32GB DDR5-5600 SODIMM
• BOE NE135FBM-N41 v8.2 (matte) 13.5", 3:2, 2256x1504, 204 ppi, 400 nits, eDP1.4, 40 pins, DC-mode dimming (not PWM)
• 55Wh battery
• RZ616/MT7922 WiFi adapter
• 4x USB-C Expansion Cards
• Capella CM3218 ambient light sensor

Opinion

• Notebookcheck review
• 204 ppi display - not ideal for HiDPI, needs 1.5x fractional scaling

Bugs

• System freezes: update to BIOS version 03.03
• Fingerprint reader fails to register: update fingerprint reader firmware
• Graphical corruption, blinking/flashing white screen: workaround: fixed in BIOS 03.05 (workaround: amdgpu.sg_display=0 or increase iGPU RAM in BIOS)
• vaapi vp9 decoding glitches: fixed in linux-firmware@97733278
• Further AMDgpu instability and performance issues
• MT7922 WiFi limited to 802.11n (WiFi 4) and 2.4GHz: configure the regulatory domain
• ectool unsupported: pending kernel patches, workaround via fork
• system wakes if AC is connected during sleep: pending firmware update, BIOS 03.05 workaround in Linux >=6.9, BIOS 03.03 workaround in Linux >=6.7, otherwise workaround via udev rules
• Bluetooth LE Audio unsupported by MT7922: see MediaTek MT7922 controller crashes after LE Setup Isochronous Data Path
• Systemd suspend-then-hibernate wakes up after 5 minutes: fixed in Linux >=6.8-rc.1 via kernel patch, workaround: rtc_cmos.use_acpi_alarm=1
• power-profiles-daemon does not set EPP: fixed in v0.20
• HDMI and DisplayPort expansion cards do not autosuspend: fixed in systemd v255 (via systemd patch)
• ambient light sensor fails to init: fixed in Linux >=6.7
• VP9 HW decoding issue, high power use when decoding H264 & vp09 with vaapi (software decoding is more efficient) and Power consumption for HW accelerated video decoding for Radeon iGPUs is simply outrageous: fixed in Linux >=6.10.7 (see AMD VCN Dynamic Power Gating)
• Headset microphone not selectable as an input source: fixed in Linux >=6.6.8 (via kernel patch, workaround via kernel params)
• ucsi_acpi errors
• USB Power Delivery issues with <60W chargers: fixed in 3.03b firmware update
• PCIe not utilising full USB 4 40Gb/s link speeds: fixed in Linux >=6.8-rc.1 via kernel patch

Enhancements

• AMD P-State Preferred Core: added in Linux >=6.9
• Adaptive Backlight Management (ABM): added in Linux >=6.9 and ppd >=0.20
• Coreboot support

BIOS

• GUI-based UEFI
• can set custom charge limit
• no "legacy" S3 deep sleep option

Software

• getUserMedia / getDisplayMedia Test Page - useful for testing webcam/screensharing
• Hardware video acceleration VA-API support via libva-mesa-driver
  • Firefox requires media.ffmpeg.vaapi.enabled=true

Sleep

• S3 sleep unsupported
  • S0ix supported, reaches S0i3.0
• consumed ~4.7% battery in ~12 hours
• Debug via drm/amd amd_s2idle.py
