Hello
The rockchip crypto driver is broken and do not pass self-tests.
This serie's goal is to permit to become usable and pass self-tests.
This whole serie is tested on a rk3328-rock64, rk3288-miqi and
rk3399-khadas-edge-v with selftests (with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y)
Regards
Changes since v1:
- select CRYPTO_ENGINE
- forgot to free fallbacks TFMs
- fixed kernel test robots warning
- add the PM patch
Changes since v2:
- Added DMA clock back to 3288 since it dont work without it
- fallback needed to select CBC and ECB configs
- Added support for rk3399
- Added more patch (style, read_poll_timeout)
Changes since v3:
- full rewrite of support for RK3399
- splited dt-binding patch in two
Changes since v4:
- Another full rewrite of support for RK3399
- Fixed dt-binding from Krzysztof Kozlowski's comments
- Use readl_poll_timeout() instead of read_poll_timeout()
- Rewrite the fallback SG tests
Changes since v5:
- fixed errors in DT binding patch
Change since v6:
- remove quotes around const values in dt-bindings

Interrupt is mandatory so the message should be printed as error.

The clock enable/disable at tfm init/exit is fragile,
if 2 tfm are init in the same time and one is removed just after,
it will leave the hardware uncloked even if a user remains.
Instead simply enable clocks at probe time.
We will do PM later.

The clock enable/disable at tfm init/exit is fragile,
if 2 tfm are init in the same time and one is removed just after,
it will leave the hardware uncloked even if a user remains.
Instead simply enable clocks at probe time.
We will do PM later.
Fixes: ce0183cb6464b ("crypto: rockchip - switch to skcipher API")

Storing the mode globally does not work if 2 requests are handled in the
same time.
We should store it in a request context.

The hardware does not handle 0 size length request, let's add a
fallback.
Furthermore fallback will be used for all unaligned case the hardware
cannot handle.

The hardware does not handle 0 size length request, let's add a
fallback.
Furthermore fallback will be used for all unaligned case the hardware
cannot handle.

The key should not be set in hardware too much in advance, this will
fail it 2 TFM with different keys generate alternative requests.
The key should be stored and used just before doing cipher operations.

Now driver have fallback for un-aligned cases, remove all code handling
those cases.
Fixes: ce0183cb6464b ("crypto: rockchip - switch to skcipher API")

* [PATCH v7 10/33] crypto: rockchip: rework by using crypto_engine

Instead of doing manual queue management, let's use the crypto/engine
for that.
In the same time, rework the requests handling to be easier to
understand (and fix all bugs related to them).
Fixes: ce0183cb6464b ("crypto: rockchip - switch to skcipher API")

Instead of doing manual queue management, let's use the crypto/engine
for that.
In the same time, rework the requests handling to be easier to
understand (and fix all bugs related to them).
Fixes: ce0183cb6464b ("crypto: rockchip - switch to skcipher API")

Instead of doing manual queue management, let's use the crypto/engine
for that.
In the same time, rework the requests handling to be easier to
understand (and fix all bugs related to them).
Fixes: ce0183cb6464b ("crypto: rockchip - switch to skcipher API")

Is there any further rationale for this?
After this change there is no longer a guaranteed reset pulse on probe
since the reset control may already be de-asserted. This is normally
the most important case for a reset as it's the only time when the state
of the hardware is unknown.
The original use of devm_add_action_or_reset() seems a bit weird already
since there doesn't seem to be any need to assert reset when the driver
is unloaded.

I am not an hw engineer, so my knowledge on reset is low.
So why not having a reset pulse on probe is a problem ?
Do you mean I must put reset asserted on probe ?

The point of the reset is to bring the hardware back to a known state.
Since we don't know what state the hardware will be in following the
bootloader or previous OS, I think the reset in probe is the only place
that it is important.
If this patch isn't fixing anything, I suggest just dropping it.

The point of the reset is to bring the hardware back to a known state.
Since we don't know what state the hardware will be in following the
bootloader or previous OS, I think the reset in probe is the only place
that it is important.
If this patch isn't fixing anything, I suggest just dropping it.

Thanks for the explanation, I will re-add the reset at probe.

rk3328 does not have the same clock names than rk3288, instead of using a complex
clock management, let's use clk_bulk to simplify their handling.

Nobody is set as maintainer of rockchip crypto, I propose to do it as I
have already reworked lot of this code.

Instead of using lot of ctx->dev->xx indirections, use an intermediate
variable for rk_crypto_info.
This will help later, when 2 different rk_crypto_info would be used.

Instead of using lot of ctx->dev->xx indirections, use an intermediate
variable for rk_crypto_info.
This will help later, when 2 different rk_crypto_info would be used.

RK3399 has 2 crypto instance, named crypto0 and crypto1 in the TRM.
Only reset for crypto1 is correctly named, but crypto0 is not.
Since nobody use them , add a 0 to be consistent with the TRM and crypto1 entries.

The rk3399 has a crypto IP handled by the rk3288 crypto driver so adds a
node for it.

Add the number of clocks needed for each compatible.
Rockchip's datasheet give maximum frequencies for some clocks, so add
checks for verifying they are within limits. Let's start with rk3288 for
clock frequency check, other will came later.

rk_ahash_reg_init() use crypto_info from TFM context, since we will
remove it, let's take if from parameters.

The RK3399 has 3 resets, so the driver to handle multiple resets.
This is done by using devm_reset_control_array_get_exclusive().

* [PATCH v7 33/33] crypto: rockchip: Add support for RK3399

The RK3399 has 2 rk3288 compatible crypto device named crypto0 and
crypto1. The only difference is lack of RSA in crypto1.
We need to add driver support for 2 parallel instance as only one need
to register crypto algorithms.
Then the driver will round robin each request on each device.
For avoiding complexity (device bringup after a TFM is created), PM is
modified to be handled per request.

@ 2022-05-08 18:59 ` Corentin Labbe

From: Corentin Labbe @ 2022-05-08 18:59 UTC (permalink / raw)

Cc: devicetree, linux-arm-kernel, linux-crypto, linux-kernel,
linux-rockchip, Corentin Labbe
The RK3399 has 2 rk3288 compatible crypto device named crypto0 and
crypto1. The only difference is lack of RSA in crypto1.
We need to add driver support for 2 parallel instance as only one need
to register crypto algorithms.
Then the driver will round robin each request on each device.
For avoiding complexity (device bringup after a TFM is created), PM is
modified to be handled per request.

The RK3399 has 2 rk3288 compatible crypto device named crypto0 and
crypto1. The only difference is lack of RSA in crypto1.
We need to add driver support for 2 parallel instance as only one need
to register crypto algorithms.
Then the driver will round robin each request on each device.
For avoiding complexity (device bringup after a TFM is created), PM is
modified to be handled per request.

I've just replied to patch 14 with a comment, but other than that I
agree that patches 1-24 look good. It would be good to get these merged
soon as crypto acceleration on Rockchip hardware has been totally broken
for several releases now.
Patches 1-13 and 15-24 are:
Reviewed-by: John Keeping <john@metanate.com>
I'm less sure about patches 25-33 as I don't really know much about the
crypto API, but it seems strange that dispatching requests to two
(nearly) identical accelerators should need so much special handling in
the driver and that there isn't some higher level management for this.

https://salsa.debian.org/kernel-team/linux/-/merge_requests/493 is where I
integrated this patch set with the Debian kernel and tested that successfully
on my Pine64 Rock64.
IOW: Tested-by Diederik de Haas <didi.debian@cknow.org>
AFAIK, this patch set has also been tested on rk3399-rockpro64 by sigmaris.
