My concern with a blacklist is that the existing tpm_tis module parameter to disable interrupts, IIRC, did not help mitigate this problem. So I would think that if there is a blackilst it should at least be amenable by module parameter for new platforms, or that specifying "interrupts=0" to tpm_tis.ko behaves identically to the device being placed on the list.
Are you sure that disabling the interrupt through the kernel commandline did not help on the T490? The reverted patches all have to do with the irq-probing / irq-handling and if tpm_tis_core_init gets passed an irq of -1 then all of that should be skipped? Regards, Hans
