The majority of xe_gt_irq_postinstall() is really focused on the hardware engine interrupts; other GT-related interrupts such as the GuC are enabled/disabled independently. Renaming the function and making it truly GT-specific will make it more clear what the intended focus is. Disabling/masking of other interrupts (such as GuC interrupts) is unnecessary since that has already happened during the irq_reset stage, and doing so will become harmful once the media GT is re-enabled since calls to xe_gt_irq_postinstall during media GT initialization would incorrectly disable the primary GT's GuC interrupts. Also, since this function is called from gt_fw_domain_init(), it's not necessary to also call it earlier during xe_irq_postinstall; just xe_irq_resume to handle runtime resume should be sufficient. v2: - Drop unnecessary !gt check. (Lucas) - Reword some comments about enable/unmask for clarity.
