net: mscc: ocelot: introduce macros for iterating over PGIDs
The current iterators are impossible to understand at first glance without switching back and forth between the definitions and their actual use in the for loops. So introduce some convenience names to help readability. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net> |

net: mscc: ocelot: generalize the "ACE/ACL" names
Access Control Lists (and their respective Access Control Entries) are specifically entries in the VCAP IS2, the security enforcement block, according to the documentation. Let's rename the structures and functions to something more generic, so that VCAP IS1 structures (which would otherwise have to be called Ingress Classification Entries) can reuse the same code without confusion. Some renaming that was done: struct ocelot_ace_rule -> struct ocelot_vcap_filter struct ocelot_acl_block -> struct ocelot_vcap_block enum ocelot_ace_type -> enum ocelot_vcap_key_type struct ocelot_ace_vlan -> struct ocelot_vcap_key_vlan enum ocelot_ace_action -> enum ocelot_vcap_action struct ocelot_ace_stats -> struct ocelot_vcap_stats enum ocelot_ace_type -> enum ocelot_vcap_key_type struct ocelot_ace_frame_* -> struct ocelot_vcap_key_* No functional change is intended.

ARM/SoC: drivers for v5.7
These are updates to SoC specific drivers that did not have
another subsystem maintainer tree to go through for some
reason:
- Some bus and memory drivers for the MIPS P5600 based
Baikal-T1 SoC that is getting added through the MIPS tree.
- There are new soc_device identification drivers for TI K3,
Qualcomm MSM8939
- New reset controller drivers for NXP i.MX8MP, Renesas
RZ/G1H, and Hisilicon hi6220
- The SCMI firmware interface can now work across ARM SMC/HVC
as a transport.
- Mediatek platforms now use a new driver for their "MMSYS"
hardware block that controls clocks and some other aspects
in behalf of the media and gpu drivers.
- Some Tegra processors have improved power management
support, including getting woken up by the PMIC and cluster
power down during idle.
- A new v4l staging driver for Tegra is added.
- Cleanups and minor bugfixes for TI, NXP, Hisilicon,
Mediatek, and Tegra.

ARM: SoC changes for v5.8
One new platform gets added, the Realtek RTD1195, which is an older Cortex-a7 based relative of the RTD12xx chips that are already supported in arch/arm64. The platform may also be extended to support running 32-bit kernels on those 64-bit chips for memory-constrained machines. In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742, an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally released in 2016 as one of the last high-end 32-bit designs. There is ongoing cleanup for the integrator, tegra, imx, and omap2 platforms, with integrator getting very close to the goal of having zero code in arch/arm/, and omap2 moving more of the chip specifics from old board code into device tree files. The Versatile Express platform is made more modular, with built-in drivers now becoming loadable modules. This is part of a greater effort for the Android OS to have a common kernel binary for all platforms and any platform specific code in loadable modules. The PXA platform drops support for Compulab's pxa2xx boards that had rather unusual flash and PCI drivers but no known users remaining. All device drivers specific to those boards can now get removed as well. Across platforms, there is ongoing cleanup, with Geert and Rob revisiting some a lot of Kconfig options.

Qualcomm driver updates for v5.8
This contains a large set of cleanups, bug fixes, general improvements and documentation fixes for the RPMH driver. It adds a debugfs mechanism for inspecting Command DB. Socinfo got the "soc_id" attribute defines and definitions for a various variants of MSM8939.

soc: fsl: qe: Replace one-element array and use struct_size() helper
The current codebase makes use of one-element arrays in the following
form:
struct something {
int length;
u8 data[1];
};
struct something *instance;
instance = kmalloc(sizeof(*instance) + size, GFP_KERNEL);
instance->length = size;
memcpy(instance->data, source, size);
but the preferred mechanism to declare variable-length types such as
these ones is a flexible array member[1][2], introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on. So, replace
the one-element array with a flexible-array member.
Also, make use of the new struct_size() helper to properly calculate the
size of struct qe_firmware.
This issue was found with the help of Coccinelle and, audited and fixed
_manually_.

firmware: raspberrypi: Introduce vl805 init routine
The Raspberry Pi 4 gets its USB functionality from VL805, a PCIe chip that implements xHCI. After a PCI reset, VL805's firmware may either be loaded directly from an EEPROM or, if not present, by the SoC's co-processor, VideoCore. RPi4's VideoCore OS contains both the non public firmware load logic and the VL805 firmware blob. The function this patch introduces triggers the aforementioned process.

net: dsa: ocelot: the MAC table on Felix is twice as large
When running 'bridge fdb dump' on Felix, sometimes learnt and static MAC
addresses would appear, sometimes they wouldn't.
Turns out, the MAC table has 4096 entries on VSC7514 (Ocelot) and 8192
entries on VSC9959 (Felix), so the existing code from the Ocelot common
library only dumped half of Felix's MAC table. They are both organized
as a 4-way set-associative TCAM, so we just need a single variable
indicating the correct number of rows.

Support 4 PTP programmable pins with only PTP_PF_PEROUT function for now. The PTP_PF_EXTTS function will be supported in the future, and it should be implemented separately for Felix and Ocelot, because of different hardware interrupt implementation in them. Since the hardware is not able to support absolute start time, the periodic clock request only allows start time 0 0. But nsec could be accepted for PPS case for phase adjustment.

The Ocelot PTP clock driver had been embedded into ocelot.c driver. It had supported basic gettime64/settime64/adjtime/adjfine functions by now which were used by both Ocelot switch and Felix switch. This patch is to move current ptp clock code out of ocelot.c driver maintaining as a single ocelot_ptp.c. For futher new features implementation, the common code could be put in ocelot_ptp.c and the switch specific code should be in specific switch driver.

net: mscc: ocelot: add action of police on vcap_is2
Ocelot has 384 policers that can be allocated to ingress ports, QoS classes per port, and VCAP IS2 entries. ocelot_police.c supports to set policers which can be allocated to police action of VCAP IS2. We allocate policers from maximum pol_id, and decrease the pol_id when add a new vcap_is2 entry which is police action.

net: dsa: felix: support changing the MTU
Changing the MTU for this switch means altering the DEV_GMII:MAC_CFG_STATUS:MAC_MAXLEN_CFG field MAX_LEN, which in turn limits the size of frames that can be received. Special accounting needs to be done for the DSA CPU port (NPI port in hardware terms). The NPI port configuration needs to be held inside the private ocelot structure, since it is now accessed from multiple places.

net: mscc: ocelot: properly account for VLAN header length when setting MRU
What the driver writes into MAC_MAXLEN_CFG does not actually represent VLAN_ETH_FRAME_LEN but instead ETH_FRAME_LEN + ETH_FCS_LEN. Yes they are numerically equal, but the difference is important, as the switch treats VLAN-tagged traffic specially and knows to increase the maximum accepted frame size automatically. So it is always wrong to account for VLAN in the MAC_MAXLEN_CFG register. Unconditionally increase the maximum allowed frame size for double-tagged traffic. Accounting for the additional length does not mean that the other VLAN membership checks aren't performed, so there's no harm done. Also, stop abusing the MTU name for configuring the MRU. There is no support for configuring the MRU on an interface at the moment. Fixes: |

net: dsa: felix: Allow unknown unicast traffic towards the CPU port module
Compared to other DSA switches, in the Ocelot cores, the RX filtering is a much more important concern. Firstly, the primary use case for Ocelot is non-DSA, so there isn't any secondary Ethernet MAC [the DSA master's one] to implicitly drop frames having a DMAC we are not interested in. So the switch driver itself needs to install FDB entries towards the CPU port module (PGID_CPU) for the MAC address of each switch port, in each VLAN installed on the port. Every address that is not whitelisted is implicitly dropped. This is in order to achieve a behavior similar to N standalone net devices. Secondly, even in the secondary use case of DSA, such as illustrated by Felix with the NPI port mode, that secondary Ethernet MAC is present, but its RX filter is bypassed. This is because the DSA tags themselves are placed before Ethernet, so the DMAC that the switch ports see is not seen by the DSA master too (since it's shifter to the right). So RX filtering is pretty important. A good RX filter won't bother the CPU in case the switch port receives a frame that it's not interested in, and there exists no other line of defense. Ocelot is pretty strict when it comes to RX filtering: non-IP multicast and broadcast traffic is allowed to go to the CPU port module, but unknown unicast isn't. This means that traffic reception for any other MAC addresses than the ones configured on each switch port net device won't work. This includes use cases such as macvlan or bridging with a non-Ocelot (so-called "foreign") interface. But this seems to be fine for the scenarios that the Linux system embedded inside an Ocelot switch is intended for - it is simply not interested in unknown unicast traffic, as explained in Allan Nielsen's presentation [0]. On the other hand, the Felix DSA switch is integrated in more general-purpose Linux systems, so it can't afford to drop that sort of traffic in hardware, even if it will end up doing so later, in software. Actually, unknown unicast means more for Felix than it does for Ocelot. Felix doesn't attempt to perform the whitelisting of switch port MAC addresses towards PGID_CPU at all, mainly because it is too complicated to be feasible: while the MAC addresses are unique in Ocelot, by default in DSA all ports are equal and inherited from the DSA master. This adds into account the question of reference counting MAC addresses (delayed ocelot_mact_forget), not to mention reference counting for the VLAN IDs that those MAC addresses are installed in. This reference counting should be done in the DSA core, and the fact that it wasn't needed so far is due to the fact that the other DSA switches don't have the DSA tag placed before Ethernet, so the DSA master is able to whitelist the MAC addresses in hardware. So this means that even regular traffic termination on a Felix switch port happens through flooding (because neither Felix nor Ocelot learn source MAC addresses from CPU-injected frames). So far we've explained that whitelisting towards PGID_CPU: - helps to reduce the likelihood of spamming the CPU with frames it won't process very far anyway - is implemented in the ocelot driver - is sufficient for the ocelot use cases - is not feasible in DSA - breaks use cases in DSA, in the current status (whitelisting enabled but no MAC address whitelisted) So the proposed patch allows unknown unicast frames to be sent to the CPU port module. This is done for the Felix DSA driver only, as Ocelot seems to be happy without it. [0]: https://www.youtube.com/watch?v=B1HhxEcU7Jg Suggested-by: Allan W.

net: mscc: ocelot: eliminate confusion between CPU and NPI port
Ocelot has the concept of a CPU port. The CPU port is represented in the forwarding and the queueing system, but it is not a physical device. The CPU port can either be accessed via register-based injection/extraction (which is the case of Ocelot), via Frame-DMA (similar to the first one), or "connected" to a physical Ethernet port (called NPI in the datasheet) which is the case of the Felix DSA switch. In Ocelot the CPU port is at index 11. In Felix the CPU port is at index 6. The CPU bit is treated special in the forwarding, as it is never cleared from the forwarding port mask (once added to it). Other than that, it is treated the same as a normal front port. Both Felix and Ocelot should use the CPU port in the same way. This means that Felix should not use the NPI port directly when forwarding to the CPU, but instead use the CPU port. This patch is fixing this such that Felix will use port 6 as its CPU port, and just use the NPI port to carry the traffic. Therefore, eliminate the "ocelot->cpu" variable which was holding the index of the NPI port for Felix, and the index of the CPU port module for Ocelot, so the variable was actually configuring different things for different drivers and causing at least part of the confusion. Also remove the "ocelot->num_cpu_ports" variable, which is the result of another confusion. The 2 CPU ports mentioned in the datasheet are because there are two frame extraction channels (register based or DMA based). This is of no relevance to the driver at the moment, and invisible to the analyzer module. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Suggested-by: Allan W.

Export the cls_flower methods from the ocelot driver and hook them up to the DSA passthrough layer. Tables for the VCAP IS2 parameters, as well as half key packing (field offsets and lengths) need to be defined for the VSC9959 core, as they are different from Ocelot, mainly due to the different port count.

net: mscc: ocelot: parameterize the vcap_is2 properties
Remove the definitions for the VCAP IS2 table from ocelot_ace.c, since it is specific to VSC7514. The VSC9959 VCAP IS2 table supports more rules (1024 instead of 64) and has a different width for the action (89 bits instead of 99).

net: mscc: ocelot: don't rely on preprocessor for vcap key/action packing
The IGR_PORT_MASK key width is different between the 11-port VSC7514 and the 6-port VSC9959 switches. And since IGR_PORT_MASK is one of the first fields of a VCAP key entry, it means that all further field offset/length pairs are shifted between the 2. The ocelot driver performs packing of VCAP half keys with the help of some preprocessor macros: - A set of macros for defining the HKO (Half Key Offset) and HKL (Half Key Length) of each possible key field. The offset of each field is defined as the sum between the offset and the sum of the previous field. - A set of accessors on top of vcap_key_set for shorter (aka less typing) access to the HKO and HKL of each key field. Since the field offsets and lengths are different between switches, defining them through the preprocessor isn't going to fly. So introduce a structure holding (offset, length) pairs and instantiate it in ocelot_board.c for VSC7514. In a future patch, a similar structure will be instantiated in felix_vsc9959.c for NXP LS1028A. The accessors also need to go. They are based on macro name concatenation, which is horrible to understand and follow.

net: mscc: ocelot: simplify tc-flower offload structures
The ocelot tc-flower offload binds a second flow block callback (apart from the one for matchall) just because it uses a different block private structure (ocelot_port_private for matchall, ocelot_port_block for flower). But ocelot_port_block just appears to be boilerplate, and doesn't help with anything in particular at all, it's just useless glue between the (global!) struct ocelot_acl_block *block pointer, and a per-netdevice struct ocelot_port_private *priv. So let's just simplify that, and make struct ocelot_port_private be the private structure for the block offload. This makes us able to use the same flow callback as in the case of matchall. This also reveals that the struct ocelot_acl_block *block is used rather strangely, as mentioned above: it is defined globally, allocated at probe time, and freed at unbind time. So just move the structure to the main ocelot structure, which gives further opportunity for simplification. Also get rid of backpointers from struct ocelot_acl_block and struct ocelot_ace_rule back to struct ocelot, by reworking the function prototypes, where necessary, to use a more DSA-friendly "struct ocelot *ocelot, int port" format. And finally, remove the debugging prints that were added during development, since they provide no useful information at this point.
