+# Hardware video decode needs firmware this image is not allowed to carry. The
+# qcom/vpu/vpu30_p1_s7.mbn in linux-firmware is the same codec signed with
+# Qualcomm's SecTools test keys, which a retail Surface's TrustZone rejects, and
+# the production-signed build exists only inside Microsoft's Surface driver
+# package, under terms that grant no redistribution right.
+#
+# So the image ships the means rather than the blob: a script that copies it out
+# of a Windows install the owner already has a licence for, and a unit that runs
+# that once on a dual-boot machine. Where Windows is gone, the script says which
+# driver pack to download and how to point it at one.
