Ondrej Zary 3cf864520e sata_via: Enable hotplug only on VT6421 ... Commit 57e5568fda ("sata_via: Implement hotplug for VT6421") adds hotplug IRQ handler for VT6421 but enables hotplug on all chips. This is a bug because it causes "irq xx: nobody cared" error on VT6420 when hot-(un)plugging a drive: [ 381.839948] irq 20: nobody cared (try booting with the "irqpoll" option) [ 381.840014] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.10.0-rc5+ #148 [ 381.840066] Hardware name: P4VM800/P4VM800, BIOS P1.60 05/29/2006 [ 381.840117] Call Trace: [ 381.840167] <IRQ> [ 381.840225] ? dump_stack+0x44/0x58 [ 381.840278] ? __report_bad_irq+0x14/0x97 [ 381.840327] ? handle_edge_irq+0xa5/0xa5 [ 381.840376] ? note_interrupt+0x155/0x1cf [ 381.840426] ? handle_edge_irq+0xa5/0xa5 [ 381.840474] ? handle_irq_event_percpu+0x32/0x38 [ 381.840524] ? handle_irq_event+0x1f/0x38 [ 381.840573] ? handle_fasteoi_irq+0x69/0xb8 [ 381.840625] ? handle_irq+0x4f/0x5d [ 381.840672] </IRQ> [ 381.840726] ? do_IRQ+0x2e/0x8b [ 381.840782] ? common_interrupt+0x2c/0x34 [ 381.840836] ? mwait_idle+0x60/0x82 [ 381.840892] ? arch_cpu_idle+0x6/0x7 [ 381.840949] ? do_idle+0x96/0x18e [ 381.841002] ? cpu_startup_entry+0x16/0x1a [ 381.841057] ? start_kernel+0x319/0x31c [ 381.841111] ? startup_32_smp+0x166/0x168 [ 381.841165] handlers: [ 381.841219] [<c12a7263>] ata_bmdma_interrupt [ 381.841274] Disabling IRQ #20 Seems that VT6420 can do hotplug too (there's no documentation) but the comments say that SCR register access (required for detecting hotplug events) can cause problems on these chips. For now, just keep hotplug disabled on anything other than VT6421. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Tejun Heo <tj@kernel.org>		2017-04-11 09:12:18 +09:00
