Subject: [PATCH] PCI: aardvark: Fix support for MSI interrupts
 | 
					 | 
				
			||||||
MIME-Version: 1.0
 | 
					 | 
				
			||||||
Content-Type: text/plain; charset=UTF-8
 | 
					 | 
				
			||||||
Content-Transfer-Encoding: 8bit
 | 
					 | 
				
			||||||
 | 
					 | 
				
			||||||
Aardvark hardware supports Multi-MSI and MSI_FLAG_MULTI_PCI_MSI is already
 | 
					 | 
				
			||||||
set for the MSI chip. But when allocating MSI interrupt numbers for
 | 
					 | 
				
			||||||
Multi-MSI, the numbers need to be properly aligned, otherwise endpoint
 | 
					 | 
				
			||||||
devices send MSI interrupt with incorrect numbers.
 | 
					 | 
				
			||||||
 | 
					 | 
				
			||||||
Fix this issue by using function bitmap_find_free_region() instead of
 | 
					 | 
				
			||||||
bitmap_find_next_zero_area().
 | 
					 | 
				
			||||||
 | 
					 | 
				
			||||||
To ensure that aligned MSI interrupt numbers are used by endpoint devices,
 | 
					 | 
				
			||||||
we cannot use Linux virtual irq numbers (as they are random and not
 | 
					 | 
				
			||||||
properly aligned). Instead we need to use the aligned hwirq numbers.
 | 
					 | 
				
			||||||
 | 
					 | 
				
			||||||
This change fixes receiving MSI interrupts on Armada 3720 boards and
 | 
					 | 
				
			||||||
allows using NVMe disks which use Multi-MSI feature with 3 interrupts.
 | 
					 | 
				
			||||||
 | 
					 | 
				
			||||||
Without this NVMe disks freeze booting as linux nvme-core.c is waiting
 | 
					 | 
				
			||||||
60s for an interrupt.
