2017-09-21MIPS: PCI: fix pcibios_map_irq section mismatchManuel Lauss1-1/+1
Drop the __init from pcibios_map_irq() to make this section mis- match go away: WARNING: vmlinux.o(.text+0x56acd4): Section mismatch in reference from the function pcibios_scanbus() to the function .init.text:pcibios_map_irq() The function pcibios_scanbus() references the function __init pcibios_map_irq(). This is often because pcibios_scanbus lacks a __init annotation or the annotation of pcibios_map_irq is wrong. Run-Tested only on Alchemy.

2013-02-01MIPS: Whitespace cleanup.Ralf Baechle1-17/+17
Having received another series of whitespace patches I decided to do this once and for all rather than dealing with this kind of patches trickling in forever. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2012-11-20MIPS: PCI: Update XLR/XLS PCI for the new PIC codeJayachandran C1-35/+34
Use the nlm_set_pic_extra_ack() call to setup the extra interrupt ACK needed by XLR PCI and XLS PCIe. Simplify the code by adding nlm_pci_link_to_irq().

2012-07-03MIPS: Netlogic: MSI enable fix for XLSGanesan Ramalingam1-9/+50
MSI interrupts do not work on XLS after commit a776c49 ( "PCI: msi: Disable msi interrupts when we initialize a pci device" ) because the change disables MSI interrupts on the XLS PCIe bridges during the PCI enumeration. Fix this by enabling MSI interrupts on the bridge in the arch_setup_msi_irq() function. A new function xls_get_pcie_link() has been introduced to get the PCI device corresponding to the top level PCIe bridge on which MSI has to be enabled. Also, update get_irq_vector() to use the new xls_get_pcie_link() function and PCI_SLOT() macro for determining the IRQ of PCI devices.

2012-02-24mips/PCI: replace pci_probe_only with pci_flagsBjorn Helgaas1-1/+1
Some architectures (alpha, mips, powerpc) have an arch-specific "pci_probe_only" flag. Others use PCI_PROBE_ONLY in pci_flags for the same purpose. This moves mips to the pci_flags approach so generic code can use the same test across all architectures.

2011-12-08MIPS: Netlogic: Move code common with XLP to common/Jayachandran C1-0/+77
- Move code that can be shared with XLP (irq.c, smp.c, time.c and xlr_console.c) to arch/mips/netlogic/common - Add asm/netlogic/haldefs.h and asm/netlogic/common.h for common and io functions shared with XLP - remove type 'nlm_reg_t *' and use uint64_t for mmio offsets - Move XLR specific code in smp.c to xlr/wakeup.c - Move XLR specific PCI code from irq.c to mips/pci/pci-xlr.c - Provide API for pic functions called from common/irq.c Signed-off-by: Jayachandran C <jayachandranc@netlogicmicro.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/2964/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
