2026-02-23mmc: core: Avoid bitfield RMW for claim/retune flagsPenghe Geng
Move claimed and retune control flags out of the bitfield word to avoid unrelated RMW side effects in asynchronous contexts. The host->claimed bit shared a word with retune flags. Writes to claimed in __mmc_claim_host() or retune_now in mmc_mq_queue_rq() can overwrite other bits when concurrent updates happen in other contexts, triggering spurious WARN_ON(!host->claimed). Convert claimed, can_retune, retune_now and retune_paused to bool to remove shared-word coupling.

2026-02-23mmc: core: Optimize time for secure erase/trim for some Kingston eMMCsLuke Wang
Kingston eMMC IY2964 and IB2932 takes a fixed ~2 seconds for each secure erase/trim operation regardless of size - that is, a single secure erase/trim operation of 1MB takes the same time as 1GB. With default calculated 3.5MB max discard size, secure erase 1GB requires ~300 separate operations taking ~10 minutes total. Add a card quirk, MMC_QUIRK_FIXED_SECURE_ERASE_TRIM_TIME, to set maximum secure erase size for those devices. This allows 1GB secure erase to complete in a single operation, reducing time from 10 minutes to just 2 seconds.

2026-02-23mmc: core: Add quirk for incorrect manufacturing dateAvri Altman
Some eMMC vendors need to report manufacturing dates beyond 2025 but are reluctant to update the EXT_CSD revision from 8 to 9. Changing the Updating the EXT_CSD revision may involve additional testing or qualification steps with customers. To ease this transition and avoid a full re-qualification process, a workaround is needed. This patch introduces a temporary quirk that re-purposes the year codes corresponding to 2010, 2011, and 2012 to represent the years 2026, 2027, and 2028, respectively. This solution is only valid for this three-year period. After 2028, vendors must update their firmware to set EXT_CSD_REV=9 to continue reporting the correct manufacturing date in compliance with the JEDEC standard. The `MMC_QUIRK_BROKEN_MDT` is introduced and enabled for all Sandisk devices to handle this behavior.

2025-08-22mmc: core: Add infrastructure for undervoltage handlingOleksij Rempel
Implement the core infrastructure to allow MMC bus types to handle REGULATOR_EVENT_UNDER_VOLTAGE events from power regulators. This is primarily aimed at allowing devices like eMMC to perform an emergency shutdown to prevent data corruption when a power failure is imminent. This patch introduces: - A new 'handle_undervoltage' function pointer to 'struct mmc_bus_ops'. Bus drivers (e.g., for eMMC) can implement this to define their emergency procedures. - A workqueue ('uv_work') in 'struct mmc_supply' to handle the event asynchronously in a high-priority context. - A new function 'mmc_handle_undervoltage()' which is called from the workqueue. It stops the host queue to prevent races with card removal, checks for the bus op, and invokes the handler. - Functions to register and unregister the regulator notifier, intended to be called by bus drivers like 'mmc_attach_mmc' when a compatible card is detected. The notifier is only registered for the main vmmc supply, as undervoltage handling for vqmmc or vqmmc2 is not required at this time.

To allow an additional external regulator to be controlled by an mmc host driver, let's add support for a vqmmc2 regulator to the mmc core. For an SD UHS-II interface the vqmmc2 regulator may correspond to the so called vdd2 supply, as described by the SD spec. Initially, only 1.8V is needed, hence limit the new helper function, mmc_regulator_set_vqmmc2() to this too. Note that, to allow for flexibility mmc host drivers need to manage the enable/disable of the vqmmc2 regulator themselves, while the regulator is looked up through the common mmc_regulator_get_supply().

2024-10-14mmc: core: Prepare to support SD UHS-II cardsUlf Hansson
The SD UHS-II interface was introduced to the SD spec v4.00 several years ago. The interface is fundamentally different from an electrical and a protocol point of view, comparing to the legacy SD interface. However, the legacy SD protocol is supported through a specific transport layer (SD-TRAN) defined in the UHS-II addendum of the spec. This allows the SD card to be managed in a very similar way as a legacy SD card, hence a lot of code can be re-used to support these new types of cards through the mmc subsystem. Moreover, an SD card that supports the UHS-II interface shall also be backwards compatible with the legacy SD interface, which allows a UHS-II card to be inserted into a legacy slot. As a matter of fact, this is already supported by mmc subsystem as of today. To prepare to add support for UHS-II, this change puts the basic foundation in the mmc core in place, allowing it to be more easily reviewed before subsequent changes implements the actual support. Basically, the approach here adds a new UHS-II bus_ops type and adds a separate initialization path for the UHS-II card. The intent is to avoid us from sprinkling the legacy initialization path, but also to simplify implementation of the UHS-II specific bits. At this point, there is only one new host ops added to manage the various ios settings needed for UHS-II. Additional host ops that are needed, are being added from subsequent changes.

SDUC memory addressing spans beyond 2TB and up to 128TB. Therefore, 38 bits are required to access the entire memory space of all sectors. Those extra 6 bits are to be carried by CMD22 prior of sending read/write/erase commands: CMD17, CMD18, CMD24, CMD25, CMD32, and CMD33. CMD22 will carry the higher order 6 bits, and must precedes any of the above commands even if it targets sector < 2TB. No error related to address or length is indicated in CMD22 but rather in the read/write command itself.

2024-10-14mmc: sd: SDUC Support RecognitionAvri Altman
Ultra Capacity SD cards (SDUC) was already introduced in SD7.0. Those cards support capacity larger than 2TB and up to including 128TB. ACMD41 was extended to support the host-card handshake during initialization. The card expects that the HCS & HO2T bits to be set in the command argument, and sets the applicable bits in the R3 returned response. On the contrary, if a SDUC card is inserted to a non-supporting host, it will never respond to this ACMD41 until eventually, the host will timed out and give up. Also, add SD CSD version 3.0 - designated for SDUC, and properly parse the csd register as the c_size field got expanded to 28 bits. Do not enable SDUC for now - leave it to the last patch in the series.

2024-10-14mmc: core: Add SD card quirk for broken poweroff notificationKeita Aihara
GIGASTONE Gaming Plus microSD cards manufactured on 02/2022 report that they support poweroff notification and cache, but they are not working correctly. Flush Cache bit never gets cleared in sd_flush_cache() and Poweroff Notification Ready bit also never gets set to 1 within 1 second from the end of busy of CMD49 in sd_poweroff_notify(). This leads to I/O error and runtime PM error state. I observed that the same card manufactured on 01/2024 works as expected. This problem seems similar to the Kingston cards fixed with commit c467c8f08185 ("mmc: Add MMC_QUIRK_BROKEN_SD_CACHE for Kingston Canvas Go Plus from 11/2019") and should be handled using quirks. CID for the problematic card is here. 12345641535443002000000145016200 Manufacturer ID is 0x12 and defined as CID_MANFID_GIGASTONE as of now, but would like comments on what naming is appropriate because MID list is not public and not sure it's right.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "Core & protocols: - Complete rework of garbage collection of AF_UNIX sockets. AF_UNIX is prone to forming reference count cycles due to fd passing functionality. New method based on Tarjan's Strongly Connected Components algorithm should be both faster and remove a lot of workarounds we accumulated over the years. - Add TCP fraglist GRO support, allowing chaining multiple TCP packets and forwarding them together. Useful for small switches / routers which lack basic checksum offload in some scenarios (e.g. PPPoE). - Support using SMP threads for handling packet backlog i.e. packet processing from software interfaces and old drivers which don't use NAPI. This helps move the processing out of the softirq jumble. - Continue work of converting from rtnl lock to RCU protection. Don't require rtnl lock when reading: IPv6 routing FIB, IPv6 address labels, netdev threaded NAPI sysfs files, bonding driver's sysfs files, MPLS devconf, IPv4 FIB rules, netns IDs, tcp metrics, TC Qdiscs, neighbor entries, ARP entries via ioctl(SIOCGARP), a lot of the link information available via rtnetlink. - Small optimizations from Eric to UDP wake up handling, memory accounting, RPS/RFS implementation, TCP packet sizing etc. - Allow direct page recycling in the bulk API used by XDP, for +2% PPS. - Support peek with an offset on TCP sockets. - Add MPTCP APIs for querying last time packets were received/sent/acked and whether MPTCP "upgrade" succeeded on a TCP socket. - Add intra-node communication shortcut to improve SMC performance. - Add IPv6 (and IPv{4,6}-over-IPv{4,6}) support to the GTP protocol driver. - Add HSR-SAN (RedBOX) mode of operation to the HSR protocol driver. - Add reset reasons for tracing what caused a TCP reset to be sent. - Introduce direction attribute for xfrm (IPSec) states. State can be used either for input or output packet processing. Things we sprinkled into general kernel code: - Add bitmap_{read,write}(), bitmap_size(), expose BYTES_TO_BITS(). This required touch-ups and renaming of a few existing users. - Add Endian-dependent __counted_by_{le,be} annotations. - Make building selftests "quieter" by printing summaries like "CC object.o" rather than full commands with all the arguments. Netfilter: - Use GFP_KERNEL to clone elements, to deal better with OOM situations and avoid failures in the .commit step. BPF: - Add eBPF JIT for ARCv2 CPUs. - Support attaching kprobe BPF programs through kprobe_multi link in a session mode, meaning, a BPF program is attached to both function entry and return, the entry program can decide if the return program gets executed and the entry program can share u64 cookie value with return program. "Session mode" is a common use-case for tetragon and bpftrace. - Add the ability to specify and retrieve BPF cookie for raw tracepoint programs in order to ease migration from classic to raw tracepoints. - Add an internal-only BPF per-CPU instruction for resolving per-CPU memory addresses and implement support in x86, ARM64 and RISC-V JITs. This allows inlining functions which need to access per-CPU state. - Optimize x86 BPF JIT's emit_mov_imm64, and add support for various atomics in bpf_arena which can be JITed as a single x86 instruction. Support BPF arena on ARM64. - Add a new bpf_wq API for deferring events and refactor process-context bpf_timer code to keep common code where possible. - Harden the BPF verifier's and/or/xor value tracking. - Introduce crypto kfuncs to let BPF programs call kernel crypto APIs. - Support bpf_tail_call_static() helper for BPF programs with GCC 13. - Add bpf_preempt_{disable,enable}() kfuncs in order to allow a BPF program to have code sections where preemption is disabled. Driver API: - Skip software TC processing completely if all installed rules are marked as HW-only, instead of checking the HW-only flag rule by rule. - Add support for configuring PoE (Power over Ethernet), similar to the already existing support for PoDL (Power over Data Line) config. - Initial bits of a queue control API, for now allowing a single queue to be reset without disturbing packet flow to other queues. - Common (ethtool) statistics for hardware timestamping. Tests and tooling: - Remove the need to create a config file to run the net forwarding tests so that a naive "make run_tests" can exercise them. - Define a method of writing tests which require an external endpoint to communicate with (to send/receive data towards the test machine). Add a few such tests. - Create a shared code library for writing Python tests. Expose the YAML Netlink library from tools/ to the tests for easy Netlink access. - Move netfilter tests under net/, extend them, separate performance tests from correctness tests, and iron out issues found by running them "on every commit". - Refactor BPF selftests to use common network helpers. - Further work filling in YAML definitions of Netlink messages for: nftables, team driver, bonding interfaces, vlan interfaces, VF info, TC u32 mark, TC police action. - Teach Python YAML Netlink to decode attribute policies. - Extend the definition of the "indexed array" construct in the specs to cover arrays of scalars rather than just nests. - Add hyperlinks between definitions in generated Netlink docs. Drivers: - Make sure unsupported flower control flags are rejected by drivers, and make more drivers report errors directly to the application rather than dmesg (large number of driver changes from Asbjørn Sloth Tønnesen). - Ethernet high-speed NICs: - Broadcom (bnxt): - support multiple RSS contexts and steering traffic to them - support XDP metadata - make page pool allocations more NUMA aware - Intel (100G, ice, idpf): - extract datapath code common among Intel drivers into a library - use fewer resources in switchdev by sharing queues with the PF - add PFCP filter support - add Ethernet filter support - use a spinlock instead of HW lock in PTP clock ops - support 5 layer Tx scheduler topology - nVidia/Mellanox: - 800G link modes and 100G SerDes speeds - per-queue IRQ coalescing configuration - Marvell Octeon: - support offloading TC packet mark action - Ethernet NICs consumer, embedded and virtual: - stop lying about skb->truesize in USB Ethernet drivers, it messes up TCP memory calculations - Google cloud vNIC: - support changing ring size via ethtool - support ring reset using the queue control API - VirtIO net: - expose flow hash from RSS to XDP - per-queue statistics - add selftests - Synopsys (stmmac): - support controllers which require an RX clock signal from the MII bus to perform their hardware initialization - TI: - icssg_prueth: support ICSSG-based Ethernet on AM65x SR1.0 devices - icssg_prueth: add SW TX / RX Coalescing based on hrtimers - cpsw: minimal XDP support - Renesas (ravb): - support describing the MDIO bus - Realtek (r8169): - add support for RTL8168M - Microchip Sparx5: - matchall and flower actions mirred and redirect - Ethernet switches: - nVidia/Mellanox: - improve events processing performance - Marvell: - add support for MV88E6250 family internal PHYs - Microchip: - add DCB and DSCP mapping support for KSZ switches - vsc73xx: convert to PHYLINK - Realtek: - rtl8226b/rtl8221b: add C45 instances and SerDes switching - Many driver changes related to PHYLIB and PHYLINK deprecated API cleanup - Ethernet PHYs: - Add a new driver for Airoha EN8811H 2.5 Gigabit PHY. - micrel: lan8814: add support for PPS out and external timestamp trigger - WiFi: - Disable Wireless Extensions (WEXT) in all Wi-Fi 7 devices drivers.

Since this is the exception rather then the rule adding a config parameter to mmc_gpiod_request_cd() seems undesirable, so instead add a new mmc_gpiod_set_cd_config() function.

2024-04-02mmc: sdio: store owner from modules with sdio_register_driver()Krzysztof Kozlowski
Modules registering driver with sdio_register_driver() might forget to set .owner field. The field is used by some of other kernel parts for reference counting (try_module_get()), so it is expected that drivers will set it. Solve the problem by moving this task away from the drivers to the core code, just like we did for platform_driver in commit 9447057eaff8 ("platform_device: use a macro instead of platform_driver_register"). Since many drivers forget to set the .owner, this effectively will fix them. Examples of fixed drivers are: ath6kl, b43, btsdio.c, ks7010, libertas, MediaTek WiFi drivers, Realtek WiFi drivers, rsi, siano, wilc1000, wl1251 and more.

2024-01-02mmc: core: Add wp_grp_size sysfs nodeLin Gui
The eMMC card can be set into write-protected mode to prevent data from being accidentally modified or deleted. Wp_grp_size (Write Protect Group Size) refers to an attribute of the eMMC card, used to manage write protection and is the CSD register [36:32] of the eMMC device. Wp_grp_size (Write Protect Group Size) indicates how many eMMC blocks are contained in each write protection group on the eMMC card. To allow userspace easy access of the CSD register bits, let's add sysfs node "wp_grp_size".

Packed commands support was removed long time ago, but some bits got left behind. Remove them. Signed-off-by: Avri Altman <avri.altman@wdc.com> Link: https://lore.kernel.org/r/20231030062226.1895692-1-avri.altman@wdc.com Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2023-11-03mmc: Add quirk MMC_QUIRK_BROKEN_CACHE_FLUSH for Micron eMMC Q2J54ABean Huo
Micron MTFC4GACAJCN eMMC supports cache but requires that flush cache operation be allowed only after a write has occurred. Otherwise, the cache flush command or subsequent commands will time out.

2023-09-27mmc: core: Allow dynamical updates of the number of requests for hsqWenchao Chen
To allow dynamical updates of the current number of used in-flight requests, let's move away from using a hard-coded value to a use a corresponding variable in the struct mmc_host. This can be valuable when optimizing for certain I/O request sequences, as shown by subsequent changes.

2023-08-25mmc: core: Add host specific tuning support for SD HS modeWenchao Chen
To support the need for host specific tuning for SD high-speed mode, let's add two new optional callbacks, ->prepare|execute_sd_hs_tuning() and let's call them when switching into the SD high-speed mode. Note that, during the tuning process it's also needed for host drivers to send commands to the SD card to verify that the tuning process succeeds. Therefore, let's also share the corresponding functions from the core to allow this.
