[PATCH v2 0/9] brcmfmac: add support for BCM4359 SDIO chipset

[Soeren Moch]

Add support for the BCM4359 chipset with SDIO interface and RSDB support
to the brcmfmac wireless network driver in patches 1-7.

Enhance devicetree of the RockPro64 arm64/rockchip board to use an
AP6359SA based wifi/bt combo module with this chipset in patches 8-9.


Chung-Hsien Hsu (1):
  brcmfmac: set F2 blocksize and watermark for 4359

Soeren Moch (5):
  brcmfmac: fix rambase for 4359/9
  brcmfmac: make errors when setting roaming parameters non-fatal
  brcmfmac: add support for BCM4359 SDIO chipset
  arm64: dts: rockchip: RockPro64: enable wifi module at sdio0
  arm64: dts: rockchip: RockPro64: hook up bluetooth at uart0

Wright Feng (3):
  brcmfmac: reset two D11 cores if chip has two D11 cores
  brcmfmac: add RSDB condition when setting interface combinations
  brcmfmac: not set mbss in vif if firmware does not support MBSS

[PATCH v2 1/9] brcmfmac: reset two D11 cores if chip has two D11 cores

[Soeren Moch]

From: Wright Feng <wright.feng@cypress.com>

There are two D11 cores in RSDB chips like 4359. We have to reset two
D11 cores simutaneously before firmware download, or the firmware may
not be initialized correctly and cause "fw initialized failed" error.

[PATCH v2 2/9] brcmfmac: set F2 blocksize and watermark for 4359

[Soeren Moch]

From: Chung-Hsien Hsu <stanley.hsu@cypress.com>

Set F2 blocksize to 256 bytes and watermark to 0x40 for 4359. Also
enable and configure F1 MesBusyCtrl. It fixes DMA error while having
UDP bi-directional traffic.

[PATCH v2 4/9] brcmfmac: make errors when setting roaming parameters non-fatal

[Soeren Moch]

4359 dongles do not support setting roaming parameters (error -52).
Do not fail the 80211 configuration in this case.

Re: [PATCH v2 5/9] brcmfmac: add support for BCM4359 SDIO chipset

[Soeren Moch]

Hi Ulf,

This patch is part of a series [1] to add support for the BCM4359
chipset with SDIO interface to the brcmfmac wireless network driver.

I just realized that this patch touches
include/linux/mmc/sdio_ids.h
and therefore I need an Ack from MMC folks. Can you please look at this?

Thanks and sorry for not including you in the original patch series
submission,
Soeren

[Soeren Moch]

From: Wright Feng <wright.feng@cypress.com>

With firmware RSDB feature
1. The maximum support interface is four.
2. The maximum difference channel is two.
3. The maximum interfaces of {station/p2p client/AP} are two.
4. The maximum interface of p2p device is one.

[PATCH v2 7/9] brcmfmac: not set mbss in vif if firmware does not support MBSS

[Soeren Moch]

From: Wright Feng <wright.feng@cypress.com>

With RSDB mode, FMAC and firmware are able to create 2 or more AP,
so we should not set mbss in vif structure if firmware does not
support MBSS feature.

[PATCH v2 8/9] arm64: dts: rockchip: RockPro64: enable wifi module at sdio0

[Soeren Moch]

RockPro64 supports an Ampak AP6359SA based wifi/bt combo module.
The BCM4359/9 wifi controller in this module is connected to sdio0,
enable this interface.

Use the in-band sdio irq instead of the out-of-band wifi_host_wake_l
signal since the latter is not working reliably on this board (probably
due to it's PCIe WAKE# connection).

Signed-off-by: Soeren Moch <smoch@web.de>

changes in v2:
- add comment about irq in commit message

Not sure where to place exactly the sdio0 node in the dts because
existing sd nodes are not sorted alphabetically.

Is this right? Comparing the binding and the naming on the schematics, 
it seems more likely that this might be the LPO clock rather than the 
TXCO clock.

On second thought I have to agree. So we need another round on this.

Just to make sure we are on the same page, I will apply patches 1-7 to
wireless-drivers-next and patches 8-9 go to some other tree? And there
are no dependencies between the brcmfmac patches and dts patches?

Yes, this also is my understanding. I'm glad if you are fine with
patches 1-7.
Heiko will pick up patches 8-9 later for linux-rockchip independently.
And if we need another round of review for patches 8-9, I think we don't
need to bother linux-wireless with this.

Thanks,

Heiko,

is this OK for you when patches 1-7 are merged now in wireless-drivers,
and then I send a v3 for patches 8-9 only for you to merge in
linux-rockchip later? Or do you prefer a full v3 for the whole series
with only this pending clock name update in patch 9?

Thanks,
Soeren

Nope, merging 1-7 from this v2 and then getting a v3 with only the dts
stuff is perfectly fine :-)

Soeren,

I suppose patch 1-7 from this serious are all good for merging. Is that 
right? If so, could you please create a rebased V3?

Chi-hsien,

Thanks for asking, but these patches are already merged in
torvalds/v5.6-rc1 as commits
1b8d2e0a9e42..2635853ce4ab

So everything already fine with this.

Thanks,

Thanks for posting this series, this chip is widely used by a large number of current Amlogic devices!

Patches 1-7 have been tested on Amlogic G12B (Khadas VIM3) hardware with 5.5-rc kernel and a LibreELEC (distro) colleague also tested with a Khadas Edge board (RK3399). The Ampak 6398S module on both boards are detected and can connect to networks to pass basic functional testing.

On the VIM3 board I do see the following warning splat:

I don’t see this on older Amlogic SoCs (GXL/GXM devices with various other BCM chips) or another Amlogic G12B device (same SoC with a different Ampak module) or some RK3399 devices, so it may be something board (Khadas VIM3) specific.

I also see some errors like:

I’m not sure if that’s of any concern, but if yes, I’d be happy to apply any debugging patches you provide to generate output.

Thanks again for working on this chipset!

Thanks for confirming that this series to add support for the BCM4359
SDIO chipset works on different boards.

> I don’t see this on older Amlogic SoCs (GXL/GXM devices with various other BCM chips) or another Amlogic G12B device (same SoC with a different Ampak module) or some RK3399 devices, so it may be something board (Khadas VIM3) specific.
Unfortunately I don't know this Khadas VIM3 board and special problems
to support brcmfmac on it.

On RockPro64 there are 2 board specific tweaks needed to get this
running (also see patch 8 in this series, and rk3399.dtsi):
- limit clock of the sdio0 port of rk3399
- enable sdio in-band irq, do not use out-of-band irq that the wifi
module supports.

I guess you need similar enhancements of the board device tree as in
patch 8 of this series for your VIM3 board.

Wider testing now points to a known SDIO issue (SoC bug) with Amlogic G12A/B hardware. The merged workaround for the bug was only tested with bcmdhd and brcmfmac may require tweaking as the same issue exhibits on an Amlogic G12B device with BCM4356 chip. Testing the series with Amlogic GXM (older) and SM1 (newer) hardware to exclude the SoC bug shows everything working as expected.

Hi Christian,

Can you elaborate on the "known SDIO issue"? Is it an issue with ADMA or 
something else. I am asking because there is a workaround in brcmfmac to 
avoid scatter-gather lists, which may or may not address the issue.

Arend

This describes the issue: https://patchwork.kernel.org/cover/10962975/

Below is the current workaround I’m using, which restricts the hack to Amlogic G12A and G12B devices that inherit “amlogic,dram-access-quirk” from a common SoC dtsi.

https://github.com/chewitt/linux/commit/187527747861b047c835f494fe3267d9b4959be1

Testing by Khadas staff found the max_segs/max_blk_count values and shows a performance impact (not a big surprise) but they appear to give a stable connection, which is better than a very unstable one. I’ve flagged things to linux-amlogic maintainer Neil Armstrong (on CC) and I expect he or colleagues will take a more scientific look in January.

NB: I’m happy to test other things. Just remember that I don’t code so you need to spoon-feed me with patches not suggestions.
