* blkdev: Refactoring block io latency histogram codesHyojun Kim2018-01-19
| | | | | | | | | | | | | The current io_latency_state structure includes entries for read and write requests. There are special types of write commands such as sync and discard (trim) commands, and the current implementation is not general enough if we want to separate latency histogram for such special commands. This change makes io_latency_state structure request-type neutral. It also changes to print the latency average. Signed-off-by: Hyojun Kim <hyojun@google.com>

| * mmc: sdio: fix alignment issue in struct sdio_funcHeiner Kallweit2017-10-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 5ef1ecf060f28ecef313b5723f1fd39bf5a35f56 ] Certain 64-bit systems (e.g. Amlogic Meson GX) require buffers to be used for DMA to be 8-byte-aligned. struct sdio_func has an embedded small DMA buffer not meeting this requirement. When testing switching to descriptor chain mode in meson-gx driver SDIO is broken therefore. Fix this by allocating the small DMA buffer separately as kmalloc ensures that the returned memory area is properly aligned for every basic data type.

| * mmc: dw_mmc: use resource_size_t to store physical addressArnd Bergmann2016-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 260b31643691e8a58683a4ccc3bdf7abfd86f54a upstream. The dw_mmc driver stores the physical address of the MMIO registers in a pointer, which requires the use of type casts, and is actually broken if anyone ever has this device on a 32-bit SoC in registers above 4GB. Gcc warns about this possibility when the driver is built with ARM LPAE enabled: mmc/host/dw_mmc.c: In function 'dw_mci_edmac_start_dma': mmc/host/dw_mmc.c:702:17: warning: cast from pointer to integer of different size cfg.dst_addr = (dma_addr_t)(host->phy_regs + fifo_offset); ^ mmc/host/dw_mmc-pltfm.c: In function 'dw_mci_pltfm_register': mmc/host/dw_mmc-pltfm.c:63:19: warning: cast to pointer from integer of different size host->phy_regs = (void *)(regs->start); This changes the code to use resource_size_t, which gets rid of the warning, the bug and the useless casts.

* mmc: core: Add mmc_regulator_set_vqmmc()Douglas Anderson2015-10-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds logic to the MMC core to set VQMMC. This is expected to be called by MMC drivers like dw_mmc as part of (or instead of) their start_signal_voltage_switch() callback. A few notes: * When setting the signal voltage to 3.3V we do our best to make VQMMC and VMMC match. It's been reported that this makes some old cards happy since they were tested back in the day before UHS when VQMMC and VMMC were provided by the same regulator. A nice side effect of this is that we don't end up on the hairy edge of VQMMC (2.7V), which some EEs claim is a little too close to the minimum for comfort. This is done in two steps. At first we try to find a VQMMC within a 0.3V tolerance of VMMC and if this is not supported by the supplying regulator we try to find a suitable voltage within the whole 2.7V-3.6V area of the spec. * The two step approach is currently necessary, as the used regulator_set_voltage_triplet(min, target, max) uses a simple implementation that just tries two basic steps: regulator_set_voltage(target, max); regulator_set_voltage(min, target); So with only one step with 2.7-3.6V borders, if a suitable voltage is a bit below VMMC, we would directly get the lowest 2.7V which some boards (like Rockchips) don't like at all. * When setting the signal voltage to 1.8V or 1.2V we aim for that specific voltage instead of picking the lowest one in the range. * We very purposely don't print errors in mmc_regulator_set_vqmmc(). There are cases where the MMC core will try several different voltages and we don't want to pollute the logs.

* mmc: core: Remove MMC_CLKGATEUlf Hansson2015-10-26
| | | | | | | | | | | | | | | | | MMC_CLKGATE was once invented to save power by gating the bus clock at request inactivity. At that time it served its purpose. The modern way to deal with power saving for these scenarios, is by using runtime PM. Nowadays, several host drivers have deployed runtime PM, but for those that haven't and which still cares power saving at request inactivity, it's certainly time to deploy runtime PM as it has been around for several years now. To simplify code to mmc core and thus decrease maintenance efforts, this patch removes all code related to MMC_CLKGATE.

* mmc: dw_mmc: add quirk for broken data transfer over schemeAddy Ke2015-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch add a new quirk to add a s/w timer to notify the driver to terminate current transfer and report a data timeout to the core, if DTO interrupt does NOT come within the given time. dw_mmc call mmc_request_done func to finish transfer depends on DTO interrupt. If DTO interrupt does not come in sending data state, the current transfer will be blocked. We got the reply from synopsys: There are two counters but both use the same value of [31:8] bits. Data timeout counter doesn't wait for stop clock and you should get DRTO even when the clock is not stopped. Host Starvation timeout counter is triggered with stop clock condition. This means that host should get DRTO and DTO interrupt. But this case really exists, when driver reads tuning data from card on RK3288-pink2 board. I measured waveforms by oscilloscope and found that card clock was always on and data lines were always holded high level in sending data state. There are two possibility that data over interrupt doesn't come in reading data state on RK3X SoCs: - get command done interrupt, but doesn't get any data-related interrupt. - get data error interrupt, but doesn't get data over interrupt.

| | | | | | | | | | | | | | | | | | | | | | | | | | The dw_mci_init_dma() may decide to not use dma, but pio instead, caused by things like wrong dma settings in the system. Till now the code dw_mci_init_slot() always assumed that dma is available when CONFIG_MMC_DW_IDMAC was defined, ignoring the host->use_dma var set during dma init. So when now the dma init failed for whatever reason, the transfer sizes would still be set for dma transfers, especially including the maximum block-count calculated from host->ring_size and resulting in a [ 4.991109] ------------[ cut here ]------------ [ 4.991111] kernel BUG at drivers/mmc/core/core.c:256!

For some controllers, which have a dedicated write-protection detection logic (like SDHCI controllers), the get_ro() callback can return bogus data in such a case. Instead of handling this on a per controller basis this patch adds a new capability flag to the MMC core that can be set to specify that the result of get_ro() is invalid.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, there is core support for tuning during initialization. There can also be a need to re-tune periodically (e.g. sdhci) or to re-tune after the host controller is powered off (e.g. after PM runtime suspend / resume) or to re-tune in response to CRC errors. The main requirements for re-tuning are: - ability to enable / disable re-tuning - ability to flag that re-tuning is needed - ability to re-tune before any request - ability to hold off re-tuning if the card is busy - ability to hold off re-tuning if re-tuning is in progress - ability to run a re-tuning timer To support those requirements 7 members are added to struct mmc_host: unsigned int can_retune:1; /* re-tuning can be used */ unsigned int doing_retune:1; /* re-tuning in progress */ unsigned int retune_now:1; /* do re-tuning at next req */ int need_retune; /* re-tuning is needed */ int hold_retune; /* hold off re-tuning */ unsigned int retune_period; /* re-tuning period in secs */ struct timer_list retune_timer; /* for periodic re-tuning */ need_retune is an integer so it can be set without needing synchronization. hold_retune is a integer to allow nesting. Various simple functions are provided to set / clear those variables. Subsequent patches take those functions into use.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 6685ac62b2f0 ("mmc: core: Convert mmc_driver to device_driver") The reverted commit went too far in simplifing the device driver parts for mmc. Let's restore the old mmc_driver to enable driver core to sooner or later to remove the ->probe(), ->remove() and ->shutdown() callbacks from the struct device_driver. Note that, the old ->suspend|resume() callbacks in the struct mmc_driver don't need to be restored, since the mmc block layer has converted to the modern system PM ops.

From Floria Fainelli. 3) Allow 'ip address' commands to initiate multicast group join/leave, from Madhu Challa. 4) Many ipv4 FIB lookup optimizations from Alexander Duyck. 5) Support EBPF in cls_bpf classifier and act_bpf action, from Daniel Borkmann. 6) Remove the ugly compat support in ARP for ugly layers like ax25, rose, etc. And use this to clean up the neigh layer, then use it to implement MPLS support. All from Eric Biederman. 7) Support L3 forwarding offloading in switches, from Scott Feldman. 8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed up route lookups even further. From Alexander Duyck. 9) Many improvements and bug fixes to the rhashtable implementation, from Herbert Xu and Thomas Graf. In particular, in the case where an rhashtable user bulk adds a large number of items into an empty table, we expand the table much more sanely. 10) Don't make the tcp_metrics hash table per-namespace, from Eric Biederman. 11) Extend EBPF to access SKB fields, from Alexei Starovoitov. 12) Split out new connection request sockets so that they can be established in the main hash table. Much less false sharing since hash lookups go direct to the request sockets instead of having to go first to the listener then to the request socks hashed underneath. From Eric Dumazet. 13) Add async I/O support for crytpo AF_ALG sockets, from Tadeusz Struk. 14) Support stable privacy address generation for RFC7217 in IPV6. From Hannes Frederic Sowa. 15) Hash network namespace into IP frag IDs, also from Hannes Frederic Sowa. 16) Convert PTP get/set methods to use 64-bit time, from Richard Cochran. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1816 commits) fm10k: Bump driver version to 0.15.2 fm10k: corrected VF multicast update fm10k: mbx_update_max_size does not drop all oversized messages fm10k: reset head instead of calling update_max_size fm10k: renamed mbx_tx_dropped to mbx_tx_oversized fm10k: update xcast mode before synchronizing multicast addresses fm10k: start service timer on probe fm10k: fix function header comment fm10k: comment next_vf_mbx flow fm10k: don't handle mailbox events in iov_event path and always process mailbox fm10k: use separate workqueue for fm10k driver fm10k: Set PF queues to unlimited bandwidth during virtualization fm10k: expose tx_timeout_count as an ethtool stat fm10k: only increment tx_timeout_count in Tx hang path fm10k: remove extraneous "Reset interface" message fm10k: separate PF only stats so that VF does not display them fm10k: use hw->mac.max_queues for stats fm10k: only show actual queues, not the maximum in hardware fm10k: allow creation of VLAN on default vid fm10k: fix unused warnings ...

* | mmc: dw_mmc: fix fifo ordering in big endianBen Dooks2015-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dw_mmc driver changes to make the IO accesors endian agnostic did not take into account the fifo accesses do not need to be swapped. To fix this add a mmci_fifo_read/write wrapper to allow these to be passed through the IO without being swapped. Since these are now specific functions, it would be easier just to store the pointer to the fifo registers in the host block instead of the offset to them. So change the host->data_offset to host->fifo_reg (which also means we catch all the places this is read or written).
