2024-02-28mmc: sdhci-esdhc-mcf: Flag the sg_miter as atomicLinus Walleij
The sg_miter used to loop over the returned sglist from a transfer in the esdhc subdriver for SDHCI can be called from atomic context so the miter needs to be atomic. sdhci_request_done() is always called from process context, either as a work or as part of the threaded interrupt handler, but the one case when we are actually calling .request_done() from an atomic context is in sdhci_irq(). Fix this by flagging the miter atomic so we always use kmap_atomic().

2024-02-28Merge branch 'eee-linkmode-bitmaps'David S. Miller
Andrew Lunn says: ==================== drivers: net: Convert EEE handling to use linkmode bitmaps EEE has until recently been limited to lower speeds due to the use of the legacy u32 for link speeds. This restriction has been lifted, with the use of linkmode bitmaps, added in the following patches: 1f069de63602 ethtool: add linkmode bitmap support to struct ethtool_keee 1d756ff13da6 ethtool: add suffix _u32 to legacy bitmap members of struct ethtool_keee 285cc15cc555 ethtool: adjust struct ethtool_keee to kernel needs 0b3100bc8fa7 ethtool: switch back from ethtool_keee to ethtool_eee for ioctl d80a52335374 ethtool: replace struct ethtool_eee with a new struct ethtool_keee on kernel side This patchset converts the remaining MAC drivers still using the old _u32 to link modes. A couple of Intel drivers do odd things with EEE, setting the autoneg bit. It is unclear why, no other driver does, ethtool does not display it, and EEE is always negotiated. One patch in this series deletes this code. With all users of the legacy _u32 changed to link modes, the _u32 values are removed from keee, and support for them in the ethtool core is removed. --- Changes in v5: - Restore zeroing eee_data.advertised in ax8817_178a - Fix lp_advertised -> supported in ixgdb - Link to v4: https://lore.kernel.org/r/20240218-keee-u32-cleanup-v4-0-71f13b7c3e60@lunn.ch Changes in v4: - Add missing conversion in igb - Add missing conversion in r8152 - Add patch to remove now unused _u32 members - Link to v3: https://lore.kernel.org/r/20240217-keee-u32-cleanup-v3-0-fcf6b62a0c7f@lunn.ch Changes in v3: - Add list of commits adding linkmodes to EEE to cover letter - Fix grammar error in cover letter. - Add Reviewed-by from Jacob Keller - Link to v2: https://lore.kernel.org/r/20240214-keee-u32-cleanup-v2-0-4ac534b83d66@lunn.ch Changes in v2: - igb: Fix type 100BaseT to 1000BaseT. - Link to v1: https://lore.kernel.org/r/20240204-keee-u32-cleanup-v1-0-fb6e08329d9a@lunn.ch ==================== Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

2024-02-28bitfield: suppress "dubious: x & !y" sparse warningJohannes Berg
There's a somewhat common pattern of using FIELD_PREP() even for single bits, e.g. cmd->info1 |= FIELD_PREP(HTT_SRNG_SETUP_CMD_INFO1_RING_FLAGS_MSI_SWAP, !!(params.flags & HAL_SRNG_FLAGS_MSI_SWAP)); which might as well be written as if (params.flags & HAL_SRNG_FLAGS_MSI_SWAP) cmd->info1 |= HTT_SRNG_SETUP_CMD_INFO1_RING_FLAGS_MSI_SWAP; (since info1 is fully initialized to start with), but in a long chain of FIELD_PREP() this really seems fine. However, it triggers a sparse warning, in the check in the macro for whether a constant value fits into the mask, as this contains a "& (_val)". In this case, this really is always intentional, so just suppress the warning by adding "0+" to the expression, indicating explicitly that this is correct.

2024-02-28stmmac: Clear variable when destroying workqueueJakub Raczynski
Currently when suspending driver and stopping workqueue it is checked whether workqueue is not NULL and if so, it is destroyed. Function destroy_workqueue() does drain queue and does clear variable, but it does not set workqueue variable to NULL. This can cause kernel/module panic if code attempts to clear workqueue that was not initialized. This scenario is possible when resuming suspended driver in stmmac_resume(), because there is no handling for failed stmmac_hw_setup(), which can fail and return if DMA engine has failed to initialize, and workqueue is initialized after DMA engine. Should DMA engine fail to initialize, resume will proceed normally, but interface won't work and TX queue will eventually timeout, causing 'Reset adapter' error. This then does destroy workqueue during reset process. And since workqueue is initialized after DMA engine and can be skipped, it will cause kernel/module panic. To secure against this possible crash, set workqueue variable to NULL when destroying workqueue. Log/backtrace from crash goes as follows: [88.031977]------------[ cut here ]------------ [88.031985]NETDEV WATCHDOG: eth0 (sxgmac): transmit queue 1 timed out [88.032017]WARNING: CPU: 0 PID: 0 at net/sched/sch_generic.c:477 dev_watchdog+0x390/0x398 <Skipping backtrace for watchdog timeout> [88.032251]---[ end trace e70de432e4d5c2c0 ]--- [88.032282]sxgmac 16d88000.ethernet eth0: Reset adapter.

2024-02-28net: stmmac: dwmac-qcom-ethqos: Update link clock rate only for RGMIISarosh Hasan
Updating link clock rate for different speeds is only needed when using RGMII, as that mode requires changing clock speed when the link speed changes. Let's restrict updating the link clock speed in ethqos_update_link_clk() to just RGMII. Other modes such as SGMII only need to enable the link clock (which is already done in probe).

Justin Iurman says: ==================== ioam6: netlink multicast event v5: - remove the "must be the destination" check before sending an ioam6 event v4: - rebase on top of net merge v3: - patchset was mistakenly superseded due to same cover title used for iproute2-next equivalent patch -> resend (renamed) v2: - fix warnings Add generic netlink multicast event support to ioam6 as another solution to share IOAM data with user space. The other one being via IPv6 raw sockets combined with ancillary data (or packet socket, if the listener does not need the processing of the IOAM Option-Type, since the hook is before in that case). This patchset focuses on the IOAM Pre-allocated Trace (the only Option-Type currently supported in the kernel), and so on IOAM "trace" events. See an example of a consumer here [1].

If we're processing an IOAM Pre-allocated Trace Option-Type (the only one supported currently), then send the trace as an ioam6 event to the netlink multicast group. This way, user space apps will be able to collect IOAM data. Reviewed-by: David Ahern <dsahern@kernel.org> Signed-off-by: Justin Iurman <justin.iurman@uliege.be> Signed-off-by: David S.

2024-02-28drm: Remove drm_num_crtcs() helperThierry Reding
The drm_num_crtcs() helper determines the number of CRTCs by iterating over the list of CRTCs that have been registered with the mode config. However, we already keep track of that number in the mode config's num_crtcs field, so we can simply retrieve the value from that and remove the extra helper function.
