2018-03-05physmem: keep only one physmem_mainDamjan Marion2-5/+5
We don't need per vlib_main physmem_main, so keep it separatelly instead of trying to keep them in sync. Change-Id: I0fbeecf4d9672d31af7a43c640a7d8f05dd6e46f Signed-off-by: Damjan Marion <damarion@cisco.com>
2018-03-05vlib: add functions to dynamically open/close PCI deviceDamjan Marion1-3/+121
Old code was only allowing PCIdevices to be scanned during startup, now driver can open and close device without restart of vpp. Change-Id: I1a06511e3f16f896101b43dac2bad420b6e6c35e Signed-off-by: Damjan Marion <damarion@cisco.com>

2018-03-04vlib: fix vlib_pci_get_device_info on when not running as rootDamjan Marion1-4/+2
While comment properly says that only first 64 bytes can be read, actual code was returning error instead being happy with 64 bytes received. Change-Id: I09c0d1d5c9fc8e1f6c59c093d81bb1ce1924281b Signed-off-by: Damjan Marion <damarion@cisco.com>

2017-12-09vlib: PCI rework to support VFIODamjan Marion1-272/+646
Also fixes old ixge driver, so it works with recent physmem changes and vfio. Change-Id: Id4be74b34daed47cd281a77eec43d6692340d882 Signed-off-by: Damjan Marion <damarion@cisco.com>
2017-10-31physmem: register region with IOMMUDamjan Marion1-0/+57
VFIO file descriptor is extracted in a hackish way, as DPDK doesn't provide imethod to retrieve it. This fixes issue with DPDK drivers not working correctly when IOMMU is enabled and external buffer memory is used.

2017-09-18Fixes for issues Coverity has reported (VPP-972)Chris Luke1-1/+1
177117: fstat() returns -1 on error; the code is checking for any positive value instead 175142: final return could never be reached; simple refactoring 175235,175236: Warning suppressed with an explicit cast to (void) 174817: Final return couldn't be reached; is is_in_order is 0 then 'rv' is already returned above 172095,172093: If is_is_set does not get set to 1, then return 0 has already been invoked 174405: Re-kill this (nothing sets rv) 171136: Looks like a cmd line flag to set test_bytes was missing; added it, and refactored the argc/argv processing to avoid two other potential segv's 176813: Add range checking for term width/height. First stab at a reasonable range is 1-512 for both. 175350: Fix implicit casting in shift operation 174272: Not a c+p error; try using a coverity annotation to ignore it 174273,175320: Annotated FORWARD_NULL Change-Id: I58d0f860fc2209f59f8d1b6b344d631b8d429ace Signed-off-by: Chris Luke <chrisy@flirble.org>
