| Subject | [PATCH net-next 00/18] net: dsa: mv88e6xxx: 802.1s and 88E6390 VTU |
| Message-ID | <tAxwd-4hS-3@gated-at.bofh.it> |
This patch series adds support for the VLAN Table Unit (a.k.a. the VTU)
to the 88E6390 family of Marvell Ethernet switch chips. The plumbing for
the per VLAN Spanning Tree support is added as a side effect of the
necessary refactoring.
The patchset is split up so that no duplication of code is introduced.
With this patchset applied, the mv88e6xxx driver has 2 new function
pointers for the VTU GetNext and VTU Load/Purge operations (with 3
implementations), both handling programmation of 802.1q and 802.1s.
On a ZII Rev C board (featuring 2 88E6390X chips) with all ports bridged
together, we obtain the following hardware VLAN configuration:
# cat /sys/class/net/br0/bridge/vlan_filtering
1
# cat /sys/class/net/br0/bridge/default_pvid
42
# bridge vlan add dev lan3 vid 666
# bridge vlan show
port vlan ids

lan7 42 PVID Egress Untagged
lan8 42 PVID Egress Untagged
lan8 42 PVID Egress Untagged
br0 42 PVID Egress Untagged
Below are the technical details for the different implementations.
All switch families have up to 3 dedicated VTU Data registers used to
program 802.1q and 802.1s, both using 2-bit values.
On 88E6185 and 88E6352 families, port membership and state are adjacent,
while the 88E6390 family share the same bits:
Bits 88E6185/88E6352 88E6390
----- ----------------- --------------------------
0-1 Port 0 membership Port 0 membership or state
2-3 Port 0 state Port 1 membership or state
4-5 Port 1 membership Port 2 membership or state
6-7 Port 1 state Port 3 membership or state
8-9 Port 2 membership Port 4 membership or state
10-11 Port 2 state Port 5 membership or state
... ... ...
The 88E6185 family programs all ports membership and state in a single
VTU GetNext or Load/Purge operation.
The 88E6352 family introduced an indirect Spanning Tree Unit table
(a.k.a. STU) which requires additional STU GetNext and Load/Purge
operations to read and write the ports state bits.
The 88E6390 family also has an STU and requires data bits to be accessed
before and after every single VTU or STU operation.
Finally, the 88E6390 family introduced a 13th bit for the VLAN ID, which
must be taken care of regardless the VTU operating mode. This means that
iterating over the VTU now starts or ends with value 8191, not 4095.
Patch 1 adds a max_vid field to the chip info structure.
Patch 2 adds 802.1q and 802.1s data to the generic VTU entry structure.
Patches 3 to 10 move helpers to a dedicated file (later made static).
Patches 11 and 12 abstract handling of the STU behind VTU operations.
Patches 13 and 14 add the new function pointers for VTU operations.
Patches 15 and 18 polish the VTU code and add VTU support for 88E6390.

| Subject | [PATCH net-next 02/18] net: dsa: mv88e6xxx: split VTU entry data member |
| Message-ID | <tAxwd-4hS-9@gated-at.bofh.it> |
| In reply to | #1631555 |
VLAN aware Marvell chips can program 802.1Q VLAN membership as well as
802.1s per VLAN Spanning Tree state using the same 3 VTU Data registers.
Some chips such as 88E6185 use different Data registers offsets for
ports state and membership, and program them in a single operation.
Other chips such as 88E6352 use the same register layout but program
them in distinct operations (an indirect table is used for 802.1s.)
Newer chips such as 88E6390 use the same offsets for both state and
membership in distinct operations, thus require multiple data accesses.
To correctly abstract this, split the "data" structure member of
mv88e6xxx_vtu_entry in two "state" and "member" members, before adding
VTU support for newer chips.

Now that the code reads both VTU and STU data on VTU GetNext operation,
fetch the STU entry data of a VTU entry at the same time.
The STU data bits are masked with the VTU data bits and they are now all
read at the same time a VTU GetNext operation is issued.

Newer chips such as the 88E6390 have a VTU Page bit in the VTU VID
register to specify a 13th bit for the VID. This can be used to support
8K VLANs.
When dumping the whole VTU, all VID bits must be set to one, including
this VTU Page bit. Add support for VID greater than 4095.

This can be used to support > 8K VLANs. Hi Vivien At the moment, this code appears to be generic to all chips. Do we need checks to ensure we don't look at this bit on older devices where it is not valid? Particularly on read. On write, we already verify the vid is less than info->max_vids, so i don't think that is a problem. > When dumping the whole VTU, all VID bits must be set to one, including > this VTU Page bit.

VID values are usually 12-bit. Marvell uses 13-bit VID values for the
88E6390 family. Because Marvell is Marvell, the 13th bit of the VID is
the 14th bit of the VID register.
It feels natural to me to stay bitwise here when handling VID values.
That's not a big deal though, one can make it clearer later if needed.
Thanks,
Vivien

Move the VTU flush operation to global1_vtu.c and call it from a
mv88e6xxx_vtu_setup helper, similarly to the ATU and PVT setup.

Add a new vtu_loadpurge operation to the chip info structure to differ
the various implementations of the VTU accesses.
Now that the STU handling is abstracted behind VTU operations, kill the
obsolete MV88E6XXX_FLAG_STU flag.

| Message-ID | <tAxwe-4hS-35@gated-at.bofh.it> |
| In reply to | #1631555 |
The code to access the VTU Data registers currently only supports the
88E6185 family and alike: 2-bit membership adjacent to 2-bit port state.
Even though the 88E6352 family introduced an indirect table to program
the VLAN Spanning Tree states, the usage of the VTU Data registers
remains the same regardless the VTU or STU operation.
Now that the mv88e6xxx_vtu_entry structure contains both port membership
and states data, factorize the code to access them in global1_vtu.c.

| Message-ID | <tAxwf-4hS-43@gated-at.bofh.it> |
| In reply to | #1631555 |
Some chips don't have a VLAN Table Unit, most of them do have a 4K
table, some others as the 88E6390 family has a 13th bit for the VID.
Add a new max_vid member to the info structure, used to check the
presence of a VTU as well as the value used to iterate from in VTU
GetNext operations.
This makes the MV88E6XXX_FLAG_VTU obsolete, thus remove it.

Extract the generic portion of code to issue an STU GetNext operation,
which will be used in other implementations.
