a86cb7e259 bus/dpaa: optimize device name parsing
Device name parsing is done on all buses during device iterations at
either EAL or ethdev levels.

When a bus implements device name parsing slowly, all iterations are
impacted. Efficient implementation is important.

The DPAA bus device name parsing has two issues: it allocates dynamic
memory and uses snprintf without a real need for it. Both can be
avoided, which improves the parsing performance.

The function is also simpler and shorter.

ac7c98d04f bus/pci: ignore missing NUMA node on Windows
On older processors, NUMA isn't bound to PCIe locality.
those cases return ERROR_NOT_FOUND in response to the
SetupDiGetDevicePropertyW call with DEVPKEY_Device_Numa_Node
attribute.

This error fails the probe process for the PCIe device.
this commit will ignore such failure and will set the
numa_node to 0.

6d10ddb408 bus/pci: fix hardware ID limit on Windows
Length of hardware IDs list is limited by REGSTR_VAL_MAX_HCID_LEN [1],
which is currently 1024. With the old limit of 260, obtaining the list
could fail in a rare occasion of a very long result (no examples known).
This also removes a bogus dependency on the maximum path length.

a20b2c01a7 build: standardize component names and defines
As discussed on the dpdk-dev mailing list[1], we can make some easy
improvements in standardizing the naming of the various components in DPDK,
and their associated feature-enabled macros.

Following this patch, each library will have the name in format,
'librte_<name>.so', and the macro indicating that library is enabled in the
build will have the form 'RTE_LIB_<NAME>'.

Similarly, for libraries, the equivalent name formats and macros are:
'librte_<class>_<name>.so' and 'RTE_<CLASS>_<NAME>', where class is the
device type taken from the relevant driver subdirectory name, i.e. 'net',
'crypto' etc.

To avoid too many changes at once for end applications, the old macro names
will still be provided in the build in this release, but will be removed
subsequently.

e9b9739264 config: remap flags used for Arm platforms
RTE_ARCH_xx flags are used to distinguish platform architectures.
These flags can be used to pick different code paths for different
architectures at compile time.
For Arm platforms, there are 3 flags in use: RTE_ARCH_ARM,
RTE_ARCH_ARMv7 and RTE_ARCH_ARM64.
RTE_ARCH_ARM64 is for 64-bit aarch64 platforms,
and RTE_ARCH_ARM & RTE_ARCH_ARMv7 are for 32-bit platforms.
RTE_ARCH_ARMv7 is for ARMv7 platforms as its name suggested.

The issue is meaning of RTE_ARCH_ARM is not clear enough.
Because no info about platform word length is included in the name.
To make the flag names more clear, a naming scheme is proposed.

RTE_ARCH_ARM (all Arm platforms)
    |
    +----RTE_ARCH_32 (New. 32-bit platforms of all architectures)
    |        |
    |        +----RTE_ARCH_ARMv7 (ARMv7 platforms)
    |        |
    |        +----RTE_ARCH_ARMv8_AARCH32 (aarch32 state on aarch64 machine)
    |
    +----RTE_ARCH_64 (64-bit platforms of all architectures)
             |
             +----RTE_ARCH_ARM64 (64-bit Arm platforms)

RTE_ARCH_32 will be explicitly defined for 32-bit platforms.

To fit into the new naming scheme, current usage of RTE_ARCH_ARM in
project is mapped to (RTE_ARCH_ARM && RTE_ARCH_32).

Matching flags for other architectures are:
RTE_ARCH_X86
    |
    +----RTE_ARCH_32
    |        |
    |        +----RTE_ARCH_I686
    |        |
    |        +----RTE_ARCH_X86_X32
    |
    +----RTE_ARCH_64
             |
             +----RTE_ARCH_X86_64

RTE_ARCH_PPC_64 ---- RTE_ARCH_64

7807a4fd38 bus/fslmc: run secondary debug app without restriction
dpaa2 hw impose limits on some HW access devices like DPMCP(Management
control Port) and DPIO (HW portal). This causes issue in their shared
usages in case of multi-process applications. It can overcome by using
whitelist/blacklist in primary and secondary applications.
However it imposes restrictions on standard debugging apps like
dpdk-procinfo, which can be used to debug any existing application.

This patch introduces reserving extra DPMCP and DPIO to be used by
secondary process if devices are not blocked previously in primary
application.
This leaves the last DPMCP and DPIO for the secondary process usages.

77a8884c44 bus/pci: fix mapping BAR containing MSI-X table
When the BAR contains MSI-X table, pci_vfio_mmap_bar() tries to skip
the table and map the rest. "map around it" is the phrase used in the
source. The function splits the BAR into two regions: the region
before the table (first part or memreg[0]) and the region after the
table (second part or memreg[1]).

For hardware that has MSI-X vector table offset 0, the first part does
not exist (memreg[0].size == 0).

  Capabilities: [60] MSI-X: Enable- Count=48 Masked-
         Vector table: BAR=2 offset=00000000
         PBA: BAR=2 offset=00001000

The mapping part of the function maps the first part, if it
exists. Then, it maps the second part, if it exists and "if mapping the
first part succeeded".

The recent change that replaces MAP_FAILED with NULL breaks the "if
mapping the first part succeeded" condition (1) in the snippet below.

    void *map_addr = NULL;
    if (memreg[0].size) {
	    /* actual map of first part */
	    map_addr = pci_map_resource(...);
    }

    /* if there's a second part, try to map it */
    if (map_addr != NULL                              // -- (1)
	    && memreg[1].offset && memreg[1].size) {
	[...]
    }

    if (map_addr == NULL) {
            RTE_LOG(ERR, EAL, "Failed to map pci BAR%d\n",
                    bar_index);
            return -1;
    }

When the first part does not exist, (1) sees map_addr is still NULL,
and the function fails. This behavior is a regression and fails
probing hardware with vector table offset 0.

Previously, (1) was "map_addr != MAP_FAILED", which meant
pci_map_resource() was actually attempted and failed. So, expand (1)
to check if the first part exists as well, to match the semantics of
MAP_FAILED.

e4abd4ff18 net/dpaa: support virtual storage profile
This patch adds support for Virtual Storage profile (VSP) feature.
With VSP support when memory pool is created, the hw buffer pool id
i.e. bpid is not allocated; the bpid is identified by dpaa flow
create API.
The memory pool of RX queue is attached to specific BMan pool
according to the VSP ID when RX queue is setup.
For fmlib based hash queue, VSP base ID is assigned to each queue.

e1ece60956 pci: move resource mapping to the PCI bus
As reported during 20.08 work for Windows, the pci_map_resource API was
built with the assumption that its flags would be passed to mmap().

This introduced a regression when adding the rte_mem_map API as reported
in the workaround commit 9d2b245937 ("pci: keep API compatibility with
mmap values").

This API was only used in the PCI bus code, so move it there.

There is no code change happening during the move.
The only change is in the pci_map_resource description where the
additional flags are now documented as rte_mem_map API flags:
- *      The additional flags for the mapping range.
+ *      The additional rte_mem_map() flags for the mapping range.

Currently with the rawdev API there is no way to check that the structure

correct type - it's just checked that it is non-NULL. Adding in the length

be used for ABI compatibility in future, since ABI changes involving

9d2b245937 pci: keep API compatibility with mmap values
The function pci_map_resource() returns MAP_FAILED in case of error.
When replacing the call to mmap() by rte_mem_map(),
the error code became NULL, breaking the API.
This function is probably not used outside of DPDK,
but it is still a problem for two reasons:
	- the deprecation process was not followed
	- the Linux function pci_vfio_mmap_bar() is broken for i40e

The error code is reverted to the Unix value MAP_FAILED.
Windows needs to define this special value (-1 as in Unix).
After proper deprecation process, the API could be changed again
if really needed.

Because of the switch from mmap() to rte_mem_map(),
another part of the API was changed: "int additional_flags"
are defined as "additional flags for the mapping range"
without mentioning it was directly used in mmap().
Currently it is directly used in rte_mem_map(),
that's why the values rte_map_flags must be mapped (sic) on the mmap ones
in case of Unix OS.

These are side effects of a badly defined API using Unix values.

54f3fb127d bus/pci: fix VF memory access
To fix CVE-2020-12888, the linux vfio-pci module will invalidate mmaps
and block MMIO access on disabled memory, it will send a SIGBUS to the
application:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=abafbc551fdd

When the application opens the vfio PCI device, the vfio-pci module will
enable the bus memory space through PCI read/write access. According to
the PCIe specification, the 'Memory Space Enable' is always zero for VF:

             Table 9-13 Command Register Changes

Bit Location | PF and VF Register Differences | PF         | VF
             | From Base                      | Attributes | Attributes
-------------+--------------------------------+------------+-----------
             | Memory Space Enable - Does not |            |
             | apply to VFs. Must be hardwired|  Base      |  0b
     1       | to 0b for VFs. VF Memory Space |            |
             | is controlled by the VF MSE bit|            |
             | in the VF Control register.    |            |
-------------+--------------------------------+------------+-----------

Afterwards the vfio-pci will initialize its own virtual PCI config space
data ('vconfig') by reading the VF's physical PCI config space, then the
'Memory Space Enable' bit in vconfig will always be 0b value. This will
make the vfio-pci treat the BAR memory space as disabled, and the SIGBUS
will be triggered if access these BARs.

By investigation, the VF PCI device *passthrough* into the Guest OS by
QEMU has the 'Memory Space Enable' with 1b value. That's because every
PCI driver will start to enable the memory space, and this action will
be hooked by vfio-pci virtual PCI read/write to set the 'Memory Space
Enable' in vconfig space to 1b. So VF runs in guest OS has 'Mem+', but
VF runs in host OS has 'Mem-'.

Align with PCI working mode in Guest/QEMU/Host, in DPDK, enable the PCI
bus memory space explicitly to avoid access on disabled memory.

Also this breaks the build for the ICC [1] because of the 'internal'
symbol check.

When function is 'inline' ICC is ignoring 'section' attribute and not
putting function to 'internal' section which breaks 'check-symbols.sh'
script with below error.

463a5245d5 bus/pci: optimise scanning with whitelist/blacklist
rte_bus_scan API scans all the available PCI devices irrespective of white
or black listing parameters then further devices are probed based on white
or black listing parameters. So unnecessary CPU cycles are wasted during
rte_pci_scan.

For Octeontx2 platform with core frequency 2.4 Ghz, rte_bus_scan consumes
around 26ms to scan around 90 PCI devices but all may not be used by the
application. So for the application which uses 2 NICs, rte_bus_scan
consumes few microseconds and rest time is saved with this patch.

Patch restricts devices to be scanned as per below mentioned conditions:
 - All devices will be scanned if no parameters are passed.
 - Only white listed devices will be scanned if white list is available.
 - All devices, except black listed, will be scanned if black list is
   available.

e4f27af0f4 bus/pci: reduce boot-up logs to absolute minimum
Some machines may have a lot of PCI devices and all of them are
not bound to DPDK. In such case the logs from EAL creates a lot of
clutter on boot-up, typically one needs to scroll the screen to
find other issues in boot-up.

This patch changes the following to reduce the clutter in
the default boot-up logs.

- Change the log-level of PCI probes to `debug`
- Introduce new driver probe as `info` log-level for the successful probe.
