linux-toradex.git/arch/tile/kernel/pci.c, branch v3.0.95 Linux kernel for Apalis and Colibri modules arch/tile: allocate PCI IRQs later in boot 2011-05-20T02:56:05+00:00 Chris Metcalf cmetcalf@tilera.com 2011-05-17T19:25:21+00:00 f4de51de2edcd26ec77bfc71b1f00b1de5a5dc20 This change became required due to some recent reworking in the platform-independent IRQ code. It is required for 2.6.38 and later. Cc: stable@kernel.org Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>

pci root complex: support for tile architecture 2010-11-24T18:13:49+00:00 Chris Metcalf cmetcalf@tilera.com 2010-11-02T16:05:10+00:00 f02cbbe657939489347cbda598401a56913ffcbd This change enables PCI root complex support for TILEPro. Unlike TILE-Gx, TILEPro has no support for memory-mapped I/O, so the PCI support consists of hypervisor upcalls for PIO, DMA, etc. However, the performance is fine for the devices we have tested with so far (1Gb Ethernet, SATA, etc.). The <asm/io.h> header was tweaked to be a little bit more aggressive about disabling attempts to map/unmap IO port space. The hacky <asm/pci-bridge.h> header was rolled into the <asm/pci.h> header and the result was simplified. Both of the latter two headers were preliminary versions not meant for release before now - oh well. There is one quirk for our TILEmpower platform, which accidentally negotiates up to 5GT and needs to be kicked down to 2.5GT. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
