In such case, calling the newly introduced function from patch 1 should be enough ? Thanks, Maxime

So the below mentioned phys such as AQR111, AQR111B0, AQR114C = supports speed up to 5Gbps which means i cannot use the function defined in the previous patch as that sets speeds up to 2.5Gbps and all lower speeds.

I understand your point, and it's hard indeed to be sure that no regression was introduced. It does feel like you're reading the PHY features, then reconstructing them almost from scratch again, but given that the PMA report looks totally incorrect, there not much choice indeed. So that's fine for me then. Maxime

So that's fine for me then. I think this is getting overly complex, so let's rewind a bit. I believe Abhishek mentioned in a previous review what the differences are between what the PHY reports when read, and what it actually supports, and the result was that there was not a single bit in the supported mask that was correct. I was hopeful that maybe Andrew would respond to that, but seems not to, so I'm putting this statement here. More on this below. Therefore, I believe that using genphy_c45_pma_read_abilities() here is a mistake. Now, looking at these two patches, patch 1 clears: ETHTOOL_LINK_MODE_10000baseT_Full_BIT ETHTOOL_LINK_MODE_10000baseKX4_Full_BIT ETHTOOL_LINK_MODE_10000baseKR_Full_BIT ETHTOOL_LINK_MODE_5000baseT_Full_BIT and sets: phy_gbit_features ETHTOOL_LINK_MODE_2500baseT_Full_BIT Patch 2 clears: ETHTOOL_LINK_MODE_10000baseT_Full_BIT ETHTOOL_LINK_MODE_10000baseKX4_Full_BIT ETHTOOL_LINK_MODE_10000baseKR_Full_BIT and sets: phy_gbit_features ETHTOOL_LINK_MODE_5000baseT_Full_BIT ETHTOOL_LINK_MODE_2500baseT_Full_BIT So, the only difference between the code in patch 1 and patch 2 is whether ETHTOOL_LINK_MODE_5000baseT_Full_BIT is set. Everything else is the same. So, the function in patch 2 can call the function in patch 1, and then do: linkmode_set_bit(ETHTOOL_LINK_MODE_5000baseT_Full_BIT, phydev->supported); However, I go back to my original point. Is it worth all this complexity clearing and setting these bits, when what is read from the PHY is so wrong? This is what was said in previous emails: | //Print added by me in the AQR driver | [ 5.583440] AQR supported mask=00,00000000,00018000,000e102c | | key points :- | | AQR115c supports 10Mbps(F/H) but feature discovery says no | AQR115C supports 1Gbps(F/H) but feature discovery says no | AQR115C supports 2500BaseX but feature discovery says no | AQR115C supports Autoneg but feature discovery says Hell no! | AQR115C does not support 10GBaseT/KX4/KR but feature discovery says yes | AQR115c does not support 5GbaseT but feature discovery says yes Providing a fuller picture: - bit 0,1 not set (10baseT_{Half,Full}) - but should be set. - bit 2,3 are set (100baseT_{Half,Full}) - correct! - bit 4 not set (1000baseT_Half) - but should be set. - bit 5 is set (1000baseT_Full) - correct! - bit 6 not set (Autoneg) - but should be set. - bit 12 is set (10000baseT_Full) - no idea! - bits 17-19 set (1000baseKX_Full, 10000baseKX4_Full, 10000baseKR_Full) - but should be clear. - bit 47 is set (2500baseT_Full) - correct! - bit 48 is set (5000baseT_Full) - but should be clear. Sorting this by status (correct, should be clear, should be set): Should be clear: - bits 17-19 set (1000baseKX_Full, 10000baseKX4_Full, 10000baseKR_Full) - bit 48 is set (5000baseT_Full) Should be set: - bit 0,1 not set (10baseT_{Half,Full}) - bit 4 not set (1000baseT_Half) - bit 6 not set (Autoneg) Correct: - bit 2,3 are set (100baseT_{Half,Full}) - bit 5 is set (1000baseT_Full) - bit 47 is set (2500baseT_Full) Unknown: - bit 12 is set (10000baseT_Full) So that's four bits to be cleared, four bits to be set, four bits are correct, and one we don't know. Is it really worth reading the PHY abilities, or would just having a list of the ethtool link modes that the PHY actually supports be a saner, more maintainable solution as originally proposed?

As you point out, it is more wrong than right. My thinking with calling the usual feature discovery mechanism and then fixing them up, is that we keep extending them. BaseT1 has been added etc. If a PHY is mostly getting it right, we might in the future get new features implemented for free, if the hardware correctly declares them. But in this case, if it cannot get even the basics mostly correct, there is little hope it will get more exotic features correct. So, i agree in Russell. Forget about asking the hardware, just hard code the correct features. Sorry for making you do extra work which you now need to discard. However, please do keep it as two patches. It makes it easier to deal with regressions on the device you cannot test if we can just revert one patch. Andrew

Remove the use of phy_set_max_speed in phy driver as the function is mainly used in MAC driver to set the max speed. Instead use get_features to fix up Phy PMA capabilities for AQR111, AQR111B0, AQR114C and AQCS109 Fixes: 038ba1dc4e54 ("net: phy: aquantia: add AQR111 and AQR111B0 PHY ID") Fixes: 0974f1f03b07 ("net: phy: aquantia: remove false 5G and 10G speed ability for AQCS109") Fixes: c278ec644377 ("net: phy: aquantia: add support for AQR114C PHY ID") Link: https://lore.kernel.org/all/20240913011635.1286027-1-quic_abchauha@quicinc.com/T/ Signed-off-by: Abhishek Chauhan <quic_abchauha@quicinc.com> --- Changes since v3 1. remove setting of 2500baseX bit introduced as part of previous patches. 2. follow reverse xmas declaration of variables. 3. remove local mask introduced as part of previous patch and optimize the logic. Changes since v2 1. seperate out the changes into two different patches. 2. use phy_gbit_features instead of initializing each and every link mode bits. 3. write seperate functions for 2.5Gbps supported phy. 4. remove FIBRE bit which was introduced in patch 1. Changes since v1 1. remove usage of phy_set_max_speed in the aquantia driver code. 2. Introduce aqr_custom_get_feature which checks for the phy id and takes necessary actions based on max_speed supported by the phy. 3. remove aqr111_config_init as it is just a wrapper function. drivers/net/phy/aquantia/aquantia_main.c | 51 +++++++++++++++--------- 1 file changed, 32 insertions(+), 19 deletions(-)
