From cbe88fbc72d9e1aa4a6f994cb6e19fa08ae5a0ba Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 31 May 2006 18:27:55 +0900 Subject: [PATCH] [PATCH] sata_sil: new interrupt handler The DMA complete bit of these controllers reflects ATA IRQ status while no DMA command is in progress. So, we can tell whether the controller is raising an interrupt or not in deterministic manner. This patch gives sata_sil its own interrupt handler which behaves much better than the original one in terms of error detection and handling. This change is also necessary for later hotplug support. Further improvements are possible, in both 2 and 4 ports versions, we can get all status with only one readl and using custom bmdma operations can further cut down register accesses.
