GpuDenyRule

Remarks

A substring rather than an exact name, because a driver's name for itself is not a stable identifier. The same GPU reports Mali-G78 on one device and Mali-G78 MC14 on another, and Adreno adds and drops the vendor prefix between driver branches. A rule keyed on equality is a rule that stops matching after an OTA update, which is worse than no rule because it looks like coverage.

⚠ The driver version is a substring too, and that is a deliberate blunt instrument. DriverVersion is a string each backend formats for humans; there is no ordering to compare against and pretending there is one would mean parsing a different scheme per vendor. A range is expressed as several rules, which is verbose and honest.

Fields and properties (3)

• public string Adapter

  Part of the adapter's name, matched case-insensitively. * matches every adapter, which is only meaningful together with a that does not.

• public string? DriverVersion

  The driver version this applies to, matched case-insensitively as a substring, or * for every version of that adapter's driver.

• public string Reason

  What goes wrong, in words a log reader can act on. Not optional — a rule nobody can review is not a deny-list, it is a device that stopped working for no stated cause.

Methods (2)

• public GpuDenyRule(string Adapter, string? DriverVersion, string Reason)

  One adapter a backend must not be used on, and why.

• public bool Matches(string name, string driverVersion)

  Whether this rule refuses a given adapter.
