[dpdk-dev] [PATCH v4 0/8] Windows bus/pci support

[talshn]

From: Tal Shnaiderman <talshn@mellanox.com>

This patchset implements the EAL and PCI functions needed for probing PMDs using RTE_KDRV_NONE on Windows.

Depends-on: series-9713 ("Windows basic memory management")

v4:
	* Fixed various warnings and naming conventions(DmitryK).
	* Fixed broken mingw-64 build(DmitryK).
	* Improved logging(DmitryK).
	* Added patch to fix warnings on rte_pci_addr logging.
	* Fixed broken make on linux/freebsd.
v3:
	* Changes in BDF and hardware ids retrieval(DmitryK).
	* Apply new generic MM to all pci unix callers(DmitryK).
	* Minor corrections in pci.c(DmitryK).
v2:
	* fix style issues.
	* fix error handing flow in pci.c
	* change eal_config.c to eal_common_config.c

Tal Shnaiderman (8):
  eal: move OS common functions to single file
  pci: use OS generic memory mapping functions
  pci: build on Windows
  pci: fix format warning on Windows
  drivers: ignore pmdinfogen generation for Windows
  drivers: fix incorrect meson import folder for Windows
  bus/pci: introduce Windows support with stubs
  bus/pci: support Windows with bifurcated drivers

[dpdk-dev] [PATCH v4 1/8] eal: move OS common functions to single file

[talshn]

From: Tal Shnaiderman <talshn@mellanox.com>

Move common functions between Unix and Windows to eal_common_config.c.

Those simple functions are getter functions for IOVA,
configuration, Multi-process.

Move rte_config and runtime_dir to be defined in a common file.

[dpdk-dev] [PATCH v4 2/8] pci: use OS generic memory mapping functions

[talshn]

From: Tal Shnaiderman <talshn@mellanox.com>

Changing all of PCIs Unix memory mapping to the
new memory allocation API wrapper.

Change all of PCI mapping function usage in
bus/pci to support the new API.

[dpdk-dev] [PATCH v4 4/8] pci: fix format warning on Windows

[talshn]

From: Tal Shnaiderman <talshn@mellanox.com>

the struct rte_pci_addr defines domain as uint32_t variable however
the PCI_PRI_FMT macro used for logging the struct sets the format
of domain to uint16_t.

The mismatch causes the following warning messages
in Windows clang build:

format specifies type 'unsigned short' but the argument
has type 'uint32_t' (aka 'unsigned int') [-Wformat]

[talshn]

From: Tal Shnaiderman <talshn@mellanox.com>

import library (/IMPLIB) in meson.build should use

The error is: fatal error LNK1149: output filename matches input filename.
The fix uses the correct folder.

[dpdk-dev] [PATCH v4 8/8] bus/pci: support Windows with bifurcated drivers

[talshn]

From: Tal Shnaiderman <talshn@mellanox.com>

Uses SetupAPI.h functions to scan PCI tree.
Uses DEVPKEY_Device_Numa_Node to get the PCI NUMA node.
Uses SPDRP_BUSNUMBER and SPDRP_BUSNUMBER to get the BDF.
scanning currently supports types RTE_KDRV_NONE.

Signed-off-by: Tal Shnaiderman <talshn@mellanox.com>
