2025-01-10net: stmmac: remove redundant code from ethtool EEE opsRussell King (Oracle)
Setting edata->tx_lpi_enabled in stmmac_ethtool_op_get_eee() gets overwritten by phylib, so there's no point setting this. In stmmac_ethtool_op_set_eee(), now that stmmac is using the result of phylib's evaluation of EEE, there is no need to handle anything in the ethtool EEE ops other than calling through to the appropriate phylink function, which will pass on to phylib the users request. As stmmac_disable_eee_mode() is now no longer called from outside stmmac_main.c, make it static.

2025-01-10net: stmmac: make EEE depend on phy->enable_tx_lpiRussell King (Oracle)
Make stmmac EEE depend on phylib's evaluation of user settings and PHY negotiation, as indicated by phy->enable_tx_lpi. This will ensure when phylib has evaluated that the user has disabled LPI, phy_init_eee() will not be called, and priv->eee_active will be false, causing LPI/EEE to be disabled. This is an interim measure - phy_init_eee() will be removed in a later patch.

2025-01-10net: stmmac: use unsigned int for eee_timerRussell King (Oracle)
Since eee_timer is used to initialise priv->tx_lpi_timer, this also should be unsigned to avoid a negative number being interpreted as a very large positive number. Note that this makes the check for negative numbers passed in as a module parameter redundant, and passing a negative number will now produce a large delay rather than the default. Since the default is used without an argument, passing a negative number would be quite obscure. However, if users do, then this will need to be revisited.

2025-01-10net: stmmac: use correct type for tx_lpi_timerRussell King (Oracle)
The ethtool interface uses u32 for tx_lpi_timer, and so does phylib. Use u32 to store this internally within stmmac rather than "int" which could misinterpret large values. Correct "value" in dwmac4_set_eee_lpi_entry_timer() to use u32 rather than int, which is derived from tx_lpi_timer. Even though this path won't be used with values larger than STMMAC_ET_MAX, this brings consistency of type usage to the stmmac code for this variable. We leave eee_timer unchanged for now, with the assumption that values up to INT_MAX will safely fit in a u32.

2025-01-10net: stmmac: move tx_lpi_timer tracking to phylibRussell King (Oracle)
When stmmac_ethtool_op_get_eee() is called, stmmac sets the tx_lpi_timer and tx_lpi_enabled members, and then calls into phylink and thus phylib. phylib overwrites these members. phylib will also cause a link down/link up transition when settings that impact the MAC have been changed. Convert stmmac to use the tx_lpi_timer setting in struct phy_device, updating priv->tx_lpi_timer each time when the link comes up, rather than trying to maintain this user setting itself. We initialise the phylib tx_lpi_timer setting by doing a get_ee-modify-set_eee sequence with the last known priv->tx_lpi_timer value. In order for this to work correctly, we also need this member to be initialised earlier. As stmmac_eee_init() is no longer called outside of stmmac_main.c, make it static.

2025-01-10scsi: st: Don't set pos_unknown just after device recognitionKai Mäkisara
Commit 9604eea5bd3a ("scsi: st: Add third party poweron reset handling") in v6.6 added new code to handle the Power On/Reset Unit Attention (POR UA) sense data. This was in addition to the existing method. When this Unit Attention is received, the driver blocks attempts to read, write and some other operations because the reset may have rewinded the tape. Because of the added code, also the initial POR UA resulted in blocking operations, including those that are used to set the driver options after the device is recognized. Also, reading and writing are refused, whereas they succeeded before this commit. Add code to not set pos_unknown to block operations if the POR UA is received from the first test_ready() call after the st device has been created. This restores the behavior before v6.6.

2025-01-10drm/amd/display: Do not elevate mem_type change to full updateLeo Li
[Why] There should not be any need to revalidate bandwidth on memory placement change, since the fb is expected to be pinned to DCN-accessable memory before scanout. For APU it's DRAM, and DGPU, it's VRAM. However, async flips + memory type change needs to be rejected. [How] Do not set lock_and_validation_needed on mem_type change. Instead, reject an async_flip request if the crtc's buffer(s) changed mem_type. This may fix stuttering/corruption experienced with PSR SU and PSR1 panels, if the compositor allocates fbs in both VRAM carveout and GTT and flips between them.

2025-01-10drm/amd/display: Do not wait for PSR disable on vbl enableLeo Li
[Why] Outside of a modeset/link configuration change, we should not have to wait for the panel to exit PSR. Depending on the panel and it's state, it may take multiple frames for it to exit PSR. Therefore, waiting in all scenarios may cause perceived stuttering, especially in combination with faster vblank shutdown. [How] PSR1 disable is hooked up to the vblank enable event, and vice versa. In case of vblank enable, do not wait for panel to exit PSR, but still wait in all other cases. We also avoid a call to unnecessarily change power_opts on disable - this ends up sending another command to dmcub fw. When testing against IGT, some crc tests like kms_plane_alpha_blend and amd_hotplug were failing due to CRC timeouts. This was found to be caused by the early return before HW has fully exited PSR1. Fix this by first making sure we grab a vblank reference, then waiting for panel to exit PSR1, before programming hw for CRC generation.

2025-01-10drm/amd/display: Reduce accessing remote DPCD overheadWayne Lin
[Why] Observed frame rate get dropped by tool like glxgear. Even though the output to monitor is 60Hz, the rendered frame rate drops to 30Hz lower. It's due to code path in some cases will trigger dm_dp_mst_is_port_support_mode() to read out remote Link status to assess the available bandwidth for dsc maniplation. Overhead of keep reading remote DPCD is considerable. [How] Store the remote link BW in mst_local_bw and use end-to-end full_pbn as an indicator to decide whether update the remote link bw or not. Whenever we need the info to assess the BW, visit the stored one first.

2025-01-10drm/amd/display: Validate mdoe under MST LCT=1 case as wellWayne Lin
[Why & How] Currently in dm_dp_mst_is_port_support_mode(), when valdidating mode under dsc decoding at the last DP link config, we only validate the case when there is an UFP. However, if the MSTB LCT=1, there is no UFP. Under this case, use root_link_bw_in_kbps as the available bw to compare.
