2022-10-03drm/i915: Reject excessive dotclocks earlyVille Syrjälä1-0/+18
Make sure modes with crazy big dotclocks are rejected early, so as to not cause problems for subsequent code via integer overflows and whatnot. These would eventually be rejected in intel_crtc_compute_pipe_mode() but that is now too late as we do the clock computations a bit earlier than that. And we don't want to just reorder the two since we still want to check the final computed dotclock against the hardware limit to make sure we didn't end up above the limit due to rounding/etc. Fixes: 0ff0e219d9b8 ("drm/i915: Compute clocks earlier") Signed-off-by: Ville Syrjälä <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Reviewed-by: Jani Nikula <[email protected]> (cherry picked from commit df2f59c5857b56a5cc40b6562b032c5d8d50cdfc) Signed-off-by: Tvrtko Ursulin <[email protected]>

2022-10-03drm/i915/psr: Fix PSR_IMR/IIR field handlingJouni Högander2-35/+59
Current PSR code is supposed to use TRANSCODER_EDP to force 0 shift for bits in PSR_IMR/IIR registers: /* * gen12+ has registers relative to transcoder and one per transcoder * using the same bit definition: handle it as TRANSCODER_EDP to force * 0 shift in bit definition */ At the time of writing the code assumption "TRANSCODER_EDP == 0" was made. This is not the case and all fields in PSR_IMR and PSR_IIR are shifted incorrectly if DISPLAY_VER >= 12. Fix this by adding separate register field defines for >=12 and add bit getter functions to keep code readability. v4: - Remove EDP from TGL definitions (José) - Use REG_BIT and REG_GENMASK (José) v3: - Add separate register field defines (José) - Add bit getter functions (José) v2: - Improve commit message (José) Cc: José Roberto de Souza <[email protected]> Cc: Mika Kahola <[email protected]> Fixes: 8241cfbe67f4 ("drm/i915/tgl: Access the right register when handling PSR interruptions") Signed-off-by: Jouni Högander <[email protected]> Reviewed-by: José Roberto de Souza <[email protected]> Signed-off-by: José Roberto de Souza <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] (cherry picked from commit 8da8e32e0b095613af2c2ce4b322240269164a8e) Signed-off-by: Tvrtko Ursulin <[email protected]>

2022-10-03irqchip/ls-extirq: Fix invalid wait context by avoiding to use regmapVladimir Oltean1-24/+63
The irqchip->irq_set_type method is called by __irq_set_trigger() under the desc->lock raw spinlock. The ls-extirq implementation, ls_extirq_irq_set_type(), uses an MMIO regmap created by of_syscon_register(), which uses plain spinlocks (the kind that are sleepable on RT). Therefore, this is an invalid locking scheme for which we get a kernel splat stating just that ("[ BUG: Invalid wait context ]"), because the context in which the plain spinlock may sleep is atomic due to the raw spinlock. We need to go raw spinlocks all the way. Make this driver ioremap its INTPCR register on its own, and stop relying on syscon to provide a regmap.

2022-10-03octeontx2-pf: mcs: Introduce MACSEC hardware offloadingSubbaraya Sundeep5-0/+1776
This patch introduces the macsec offload feature to cn10k PF netdev driver. The macsec offload ops like adding, deleting and updating SecYs, SCs, SAs and stats are supported. XPN support will be added in later patches. Some stats use same counter in hardware which means based on the SecY mode the same counter represents different stat. Hence when SecY mode/policy is changed then snapshot of current stats are captured. Also there is no provision to specify the unique flow-id/SCI per packet to hardware hence different mac address needs to be set for macsec interfaces.

CN10K-B and CNF10K-B has macsec block(MCS) to encrypt and decrypt packets at MAC level. This block is a global resource with hardware resources like SecYs, SCs and SAs and is in between NIX block and RPM LMAC. CN10K-B silicon has only one MCS block which receives packets from all LMACS whereas CNF10K-B has seven MCS blocks for seven LMACs. Both MCS blocks are similar in operation except for few register offsets and some configurations require writing to different registers. Those differences between IPs are handled using separate ops.

2022-10-03net: fec: using page pool to manage RX buffersShenwei Wang3-58/+119
This patch optimizes the RX buffer management by using the page pool. The purpose for this change is to prepare for the following XDP support. The current driver uses one frame per page for easy management. Added __maybe_unused attribute to the following functions to avoid the compiling warning. Those functions will be removed by a separate patch once this page pool solution is accepted. - fec_enet_new_rxbdp - fec_enet_copybreak The following are the comparing result between page pool implementation and the original implementation (non page pool). --- small packet (64 bytes) testing are almost the same --- no matter what the implementation is --- on both i.MX8 and i.MX6SX

But when "pad + len > fp->rx_buf_size" is true, bnx2x_tpa_stop() returns without releasing the new_data, which will lead to a memory leak.

Some multigig SFPs from RollBall and Hilink do not expose functional MDIO access to the internal PHY of the SFP via I2C address 0x56 (although there seems to be read-only clause 22 access on this address). Instead these SFPs PHY can be accessed via I2C via the SFP Enhanced Digital Diagnostic Interface - I2C address 0x51. The SFP_PAGE has to be selected to 3 and the password must be filled with 0xff bytes for this PHY communication to work. This extends the mdio-i2c driver to support this protocol by adding a special parameter to mdio_i2c_alloc function via which this RollBall protocol can be selected.

2022-10-03net: phy: marvell10g: select host interface configurationRussell King1-0/+112
Select the host interface configuration according to the capabilities of the host if the host provided them. This is currently provided only when connecting PHY that is inside a SFP. The PHY supports several configurations of host communication: - always communicate with host in 10gbase-r, even if copper speed is lower (rate matching mode), - the same as above but use xaui/rxaui instead of 10gbase-r, - switch host SerDes mode between 10gbase-r, 5gbase-r, 2500base-x and sgmii according to copper speed, - the same as above but use xaui/rxaui instead of 10gbase-r. This mode of host communication, called MACTYPE, is by default selected by strapping pins, but it can be changed in software. This adds support for selecting this mode according to which modes are supported by the host. This allows the kernel to: - support SFP modules with 88X33X0 or 88E21X0 inside them Note: we use mv3310_select_mactype() for both 88X3310 and 88X3340, although 88X3340 does not support XAUI. This is not a problem because 88X3340 does not declare XAUI in it's supported_interfaces, and so this function will never choose that MACTYPE.

Pass the supported PHY interface types to phylib if the PHY we are connecting is inside a SFP, so that the PHY driver can select an appropriate host configuration mode for their interface according to the host capabilities. For example the Marvell 88X3310 PHY inside RollBall SFP modules defaults to 10gbase-r mode on host's side, and the marvell10g driver currently does not change this setting. But a host may not support 10gbase-r. For example Turris Omnia only supports sgmii, 1000base-x and 2500base-x modes. The PHY can be configured to use those modes, but in order for the PHY driver to do that, it needs to know which modes are supported.

On pre-ddi platforms we have slightly different code being used for HDMI TMDS clock to dotclock conversion between the state computation and state readout. Both of these need to round the same way in order to not get a mismatch between the computed and read out states. Fix up the rounding direction in the readout path to match what is used during state computation. Another option would to just use intel_crtc_dotclock() in the readout path as well, but I don't really want to do that as the current code more accurately represents how the hardware really works; The HDMI port register defines whether we're actually outputting 8bpc or 12bpc over HDMI, and the PIPECONF bpc setting just defines what goes over FDI between the CPU and PCH. The fact that we try to cram all that into a single pipe_bpp during state computation is perhaps not entirely great...
