| * | | | | printk: implement support for extended console driversTejun Heo2015-06-25

The metadata is currently available only through /dev/kmsg and stripped out before passed onto console drivers. We want this metadata to be available to console drivers too so that console consumers can get full information including the metadata and dictionary, which among other things can be used to detect whether messages got lost in transit. This patch implements support for extended console drivers. Consoles can indicate that they want extended messages by setting the new CON_EXTENDED flag and they'll be fed messages formatted the same way as /dev/kmsg. "<level>,<sequnum>,<timestamp>,<contflag>;<message text>\n" If extended consoles exist, in-kernel fragment assembly is disabled. This ensures that all messages emitted to consoles have full metadata including sequence number. The contflag carries enough information to reassemble the fragments from the reader side trivially. Note that this only affects /dev/kmsg. Regular console and /proc/kmsg outputs are not affected by this change. * Extended message formatting for console drivers is enabled iff there are registered extended consoles. * Comment describing /dev/kmsg message format updated to add missing contflag field and help distinguishing variable from verbatim terms.

The one and only way to have N zram devices is to specify num_devices module parameter (default value: 1). IOW if, for some reason, at some point, user wants to have N + 1 devies he/she must umount all the existing devices, unload the module, load the module passing num_devices equals to N + 1. And do this again, if needed. This patch introduces zram control sysfs class, which has two sysfs attrs: - hot_add -- add a new zram device - hot_remove -- remove a specific (device_id) zram device hot_add sysfs attr is read-only and has only automatic device id assignment mode (as requested by Minchan Kim). read operation performed on this attr creates a new zram device and returns back its device_id or error status. Usage example: # add a new specific zram device cat /sys/class/zram-control/hot_add 2 # remove a specific zram device echo 4 > /sys/class/zram-control/hot_remove Returning zram_add() error code back to user (-ENOMEM in this case) cat /sys/class/zram-control/hot_add cat: /sys/class/zram-control/hot_add: Cannot allocate memory NOTE, there might be users who already depend on the fact that at least zram0 device gets always created by zram_init().

But for situation when /dev/mem usage is disabled, the utils have to use dmi sysfs instead, which doesn't represent SMBIOS entry and adds code/delay redundancy when direct access for table is needed. So this patch creates dmi/tables and adds SMBIOS entry point to allow utils in question to work correctly without /dev/mem. Also patch adds raw dmi table to simplify dmi table processing in user space, as proposed by Jean Delvare.

There we have slightly different carrier boards than the janz-cmodio supported in the kernel sources, called CAN-PCI2 with two submodules. But the pci configuration regions are identical. So extending the supported pci devices to the corresponding device ids is sufficient to get the drivers working. * The old ICAN3-modules with firmware 1.28 need more then 250ms for the restart after reset. I've increased the timeout to 500ms. * The janz_ican3 module uses the raw can services of the Janz-firmware, this means firmware must be ICANOS/2. Our ICAN3-modules are equipped with CAL/CANopen-firmware, so I must use the appropriate commands for the layer management services. Te driver detects the firmware after module reset and selects the commands matching the firmware. This affects the bus on/off-command (ican3_set_bus_state) and the configuration of the bittiming (ican3_set_bittiming). For better diagnostics the detected firmware string is presented as sysfs attribute (fwinfo).

This may be needed for bridge setups used for network troubleshooting or any other scenario where forwarding of LLDP frames is desired (e.g. bridge connecting a virtual machine to real switch transmitting LLDP frames that virtual machine needs to receive). Tested on a simple bridge setup with two interfaces and host transmitting LLDP frames on one side of this bridge (used lldpd). Setting group_fwd_mask as described above lets LLDP frames traverse bridge. Signed-off-by: Bernhard Thaler <bernhard.thaler@wvnet.at> Signed-off-by: David S. Miller <davem@davemloft.net>

Current no statistics are available for tape I/O and there is no easy way to reuse the block layer statistics for tape as tape is a character device and does not have perform I/O in sector sized chunks (the size of the data written to tape can change). For tapes we also need extra stats related to things like tape movement (via other I/O). There have been multiple end users requesting statistics including AT&T (and some HP customers who have not given permission to be named). It is impossible for them to investigate any issues related to tape performance in a non-invasive way.

Add a per-device sysfs attribute to allow the user to control how long a request, that is a reasonable merge candidate, can be queued on the request queue. The resolution of this request dispatch deadline is in microseconds (ranging from 1 to 100000 usecs), to set a 20us deadline: echo 20 > /sys/block/dm-7/dm/rq_based_seq_io_merge_deadline The dm_request_fn's merge heuristic and associated extra accounting is disabled by default (rq_based_seq_io_merge_deadline is 0). This sysfs attribute is not applicable to bio-based DM devices so it will only ever report 0 for them. By allowing a request to remain on the queue it will block others requests on the queue. But introducing a short dequeue delay has proven very effective at enabling certain sequential IO workloads on really fast, yet IOPS constrained, devices to build up slightly larger IOs -- yielding 90+% throughput improvements. Having precise control over the time taken to wait for larger requests to build affords control beyond that of waiting for certain IO sizes to accumulate (which would require a deadline anyway). This knob will only ever make sense with sequential IO workloads and the particular value used is storage configuration specific. Given the expected niche use-case for when this knob is useful it has been deemed acceptable to expose this relatively crude method for crafting optimal IO on specific storage -- especially given the solution is simple yet effective. In the context of DM multipath, it is advisable to tune this sysfs attribute to a value that offers the best performance for the common case (e.g. if 4 paths are expected active, tune for that; if paths fail then performance may be slightly reduced). Alternatives were explored to have request-based DM autotune this value (e.g. if/when paths fail) but they were quickly deemed too fragile and complex to warrant further design and development time. If this problem proves more common as faster storage emerges we'll have to look at elevating a generic solution into the block core.
