feat: enable earth-pt3 dvb driver - #1682

Conversation
Earthsoft PT1/PT2/PT3 are ISDB-T/S PCIe tuner cards that are common in Japan. The in-tree earth-pt3 driver was the only piece missing: its dependencies (tc90522 demodulator, qm1d1c0042 and mxl301rf tuners) are already built as modules, so this only flips CONFIG_DVB_PT3 on for amd64. Enabling it here lets a matching system extension ship the modules, the same way dvb-cx23885 does. Signed-off-by: Ruk Doe <info@doany.io> Signed-off-by: Andrey Smirnov <andrey.smirnov@siderolabs.com>

The Earthsoft PT3 is an ISDB-T/S PCIe tuner card widely used for terrestrial and satellite TV recording in Japan. This extension ships the earth-pt3 driver and the modules it pulls in (tc90522 demodulator, qm1d1c0042 and mxl301rf tuners, dvb-core and mc), modelled on the existing dvb-cx23885 extension. The card needs no firmware blob, so nothing is downloaded at build time. The modules are blacklisted by default, matching dvb-cx23885, so the driver is only loaded when the machine config asks for it. This depends on siderolabs/pkgs#1682, which enables CONFIG_DVB_PT3.

What
Enable
CONFIG_DVB_PT3=mfor amd64.Why
Earthsoft PT1/PT2/PT3 are ISDB-T/S PCIe tuner cards, widely used for terrestrial and satellite TV recording in Japan. Talos currently cannot drive them because the in-tree
earth-pt3driver is not enabled, so there is no way to run a recording workload on Talos with this hardware.Everything the driver needs is already built as a module in this config, so the change is a single line:
CONFIG_DVB_PT3mCONFIG_DVB_TC90522(demodulator)mCONFIG_MEDIA_TUNER_QM1D1C0042(ISDB-S tuner)mCONFIG_MEDIA_TUNER_MXL301RF(ISDB-T tuner)mOnly
config-amd64is touched: the card is PCIe and there is no practical arm64 use.Follow-up
A
dvb/pt3system extension that shipsearth-pt3.koand its dependencies, modelled on the existingdvb-cx23885extension, needs this to land first. I will open that PR againstsiderolabs/extensionsonce the kernel builds the module.I do not have a build environment large enough to compile the kernel locally, so this relies on CI.
