* Add the sfxge(4) device driver, providing support for 10Gb Ethernet adaptersPhilip Paeps2011-11-2845-0/+38371
| | | | | | | | | | | | | | | | | based on Solarflare SFC9000 family controllers. The driver supports jumbo frames, transmit/receive checksum offload, TCP Segmentation Offload (TSO), Large Receive Offload (LRO), VLAN checksum offload, VLAN TSO, and Receive Side Scaling (RSS) using MSI-X interrupts. This work was sponsored by Solarflare Communications, Inc. My sincere thanks to Ben Hutchings for doing a lot of the hard work! Sponsored by: Solarflare Communications, Inc.

| | | | | | | | | | | | | | | The DC calibration result obtained during initialization can't be passed over to the runtime firmware on 6050 devices. Instead let the runtime firmware do the calibration itself. This fixes support for the 6050 series devices.

| | | | | | | | | | | | | | | | | The maximum TSO frame size should be: maximum IP datagram size (65535 bytes) + Ethernet header size (14 bytes) + 2 * VLAN tag size (4 bytes) [1]. [1] We need to multiply by 2 to account for the double VLAN tag provision added in IEEE 802.1ad.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | As it turns out, r186347 actually is insufficient to avoid the use of the curthread-accessing part of mtx_{,un}lock(9) when using a r210623-style curthread implementation on sparc64, crashing the kernel in its early cycles as PCPU isn't set up, yet (and can't be set up as OFW is one of the things we need for that, which leads to a chicken-and-egg problem). What happens is that due to the fact that the idea of r210623 actually is to allow the compiler to cache invocations of curthread, it factors out obtaining curthread needed for both mtx_lock(9) and mtx_unlock(9) to before the branch based on kobj_mutex_inited when compiling the kernel without the debugging options. So change kobj_class_compile_static(9) to just never acquire kobj_mtx, effectively restricting it to its documented use, and add a kobj_init_static(9) for initializing objects using a class compiled with the former and that also avoids using mutex(9) (and malloc(9)). Also assert in both of these functions that they are used in their intended way only. While at it, inline kobj_register_method() and kobj_unregister_method() as there wasn't much point for factoring them out in the first place and so that a reader of the code has to figure out the locking for fewer functions missing a KOBJ_ASSERT.

A new feature flag NCR_F_LARGEXFER was introduced so we just need to check for this one and not for individual controllers supporting large transfers in several places. - Let the LSI64854 core load transfer buffers using BUS_DMA_NOWAIT as the NCR53C9x core can't handle EINPROGRESS. Due to lack of bounce buffers support, sparc64 doesn't actually use EINPROGRESS and likely never will, as an example for writing additional front-ends for the NCR53C9x core it makes sense to set BUS_DMA_NOWAIT anyway though. - Some minor cleanup.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Import the common MII bitbang'ing code from NetBSD and convert drivers to take advantage of it instead of duplicating it. This reduces the size of the i386 GENERIC kernel by about 8k. The only potential in-tree users left unconverted are ed(4) and xe(4). Xe(4) generally should be changed to use miibus(4) instead of implementing PHY handling on its own, as otherwise it makes not much sense to add a dependency on miibus(4)/mii_bitbang(4) to it just for the MII bitbang'ing code. Ed(4) has some chip specific things interwinded with the MII bitbang'ing code and it's unclear whether it can be converted to common code, at least not without thorough testing of all the various chips supported by ed(4). The common MII bitbang'ing code also is useful in the embedded space for using GPIO pins to implement MII access. - Based on lessons learnt with dc(4) (see r185750), add bus barriers to the MII bitbang read and write functions of the other drivers converted in order to ensure the intended ordering. Given that register access via an index register as well as register bank/window switching is subject to the same problem, also add bus barriers to the respective functions of smc(4), tl(4) and xl(4). - Sprinkle some const.

| | | | | | | | | | | | | | | | | | | | | | | | option is defined. This sysctl can be queried by feature_present(3). Query for this feature in /sbin/atacontrol and /usr/sbin/burncd. If these utilities detect that ATA_CAM is enabled, then these utilities will error out. These utilities are compatible with the old ATA driver, but are incomptible with the new ATA_CAM driver. By erroring out, we give end-users an idea as to what remedies to use, and reduce the need for them to file PR's. For atacontrol, camcontrol must be used instead, and for burncd, alternative utilties from the ports collection must be used such as sysutils/cdrtools. In future, maybe someone can re-write burncd to work with ATA_CAM, but at least for now, we give a somewhat useful error message to end users.

Desriptor sense is a new sense data format that originated in SPC-3. Among other things, it allows for an 8-byte info field, which is necessary to pass back block numbers larger than 4 bytes. This change adds a number of new functions to scsi_all.c (and therefore libcam) that abstract out most access to sense data. This includes a bump of CAM_VERSION, because the CCB ABI has changed. Userland programs that use the CAM pass(4) driver will need to be recompiled. camcontrol.c: Change uses of scsi_extract_sense() to use scsi_extract_sense_len(). Use scsi_get_sks() instead of accessing sense key specific data directly. scsi_modes: Update the control mode page to the latest version (SPC-4). scsi_cmds.c, scsi_target.c: Change references to struct scsi_sense_data to struct scsi_sense_data_fixed. This should be changed to allow the user to specify fixed or descriptor sense, and then use scsi_set_sense_data() to build the sense data. ps3cdrom.c: Use scsi_set_sense_data() instead of setting sense data manually. cam_periph.c: Use scsi_extract_sense_len() instead of using scsi_extract_sense() or accessing sense data directly. cam_ccb.h: Bump the CAM_VERSION from 0x15 to 0x16. The change of struct scsi_sense_data from 32 to 252 bytes changes the size of struct ccb_scsiio, but not the size of union ccb. So the version must be bumped to prevent structure mis-matches. scsi_all.h: Lots of updated SCSI sense data and other structures. Add function prototypes for the new sense data functions. Take out the inline implementation of scsi_extract_sense(). It is now too large to put in a header file. Add macros to calculate whether fields are present and filled in fixed and descriptor sense data scsi_all.c: In scsi_op_desc(), allow the user to pass in NULL inquiry data, and we'll assume a direct access device in that case. Changed the SCSI RESERVED sense key name and description to COMPLETED, as it is now defined in the spec. Change the error recovery action for a number of read errors to prevent lots of retries when the drive has said that the block isn't accessible. This speeds up reconstruction of the block by any RAID software running on top of the drive (e.g. ZFS). In scsi_sense_desc(), allow for invalid sense key numbers. This allows calling this routine without checking the input values first. Change scsi_error_action() to use scsi_extract_sense_len(), and handle things when invalid asc/ascq values are encountered. Add a new routine, scsi_desc_iterate(), that will call the supplied function for every descriptor in descriptor format sense data. Add scsi_set_sense_data(), and scsi_set_sense_data_va(), which build descriptor and fixed format sense data. They currently default to fixed format sense data. Add a number of scsi_get_*() functions, which get different types of sense data fields from either fixed or descriptor format sense data, if the data is present. Add a number of scsi_*_sbuf() functions, which print formatted versions of various sense data fields. These functions work for either fixed or descriptor sense. Add a number of scsi_sense_*_sbuf() functions, which have a standard calling interface and print the indicated field. These functions take descriptors only. Add scsi_sense_desc_sbuf(), which will print a formatted version of the given sense descriptor. Pull out a majority of the scsi_sense_sbuf() function and put it into scsi_sense_only_sbuf(). This allows callers that don't use struct ccb_scsiio to easily utilize the printing routines. Revamp that function to handle descriptor sense and use the new sense fetching and printing routines. Move scsi_extract_sense() into scsi_all.c, and implement it in terms of the new function, scsi_extract_sense_len(). The _len() version takes a length (which should be the sense length - residual) and can indicate which fields are present and valid in the sense data. Add a couple of new scsi_get_*() routines to get the sense key, asc, and ascq only. mly.c: Rename struct scsi_sense_data to struct scsi_sense_data_fixed. sbp_targ.c: Use the new sense fetching routines to get sense data instead of accessing it directly. sbp.c: Change the firewire/SCSI sense data transformation code to use struct scsi_sense_data_fixed instead of struct scsi_sense_data. This should be changed later to use scsi_set_sense_data(). ciss.c: Calculate the sense residual properly. Use scsi_get_sense_key() to fetch the sense key. mps_sas.c, mpt_cam.c: Set the sense residual properly. iir.c: Use scsi_set_sense_data() instead of building sense data by hand. iscsi_subr.c: Use scsi_extract_sense_len() instead of grabbing sense data directly. umass.c: Use scsi_set_sense_data() to build sense data. Grab the sense key using scsi_get_sense_key(). Calculate the sense residual properly. isp_freebsd.h: Use scsi_get_*() routines to grab asc, ascq, and sense key values. Calculate and set the sense residual. Approved by: re (kib) Sponsored by: Spectra Logic Corporation Notes: svn path=/stable/9/; revision=226067

| | | | | | | | | | | | | | | | | | | | PV devices with the ioemu attribute set. sys/dev/xen/netfront/netfront.c: o If a mac address for the interface cannot be found in the front-side XenStore tree, look for an entry in the back-side tree. With ioemu devices, the emulator does not populate the front side tree and neither does Xend. o Return an error rather than panic when an attach attempt fails.

* Correct suspend/resume support in the Netfront driver.Justin T. Gibbs2011-09-211-26/+54
| | | | | | | | | | | | | | | | | | | | | | | | Sponsored by: BQ Internet sys/dev/xen/netfront/netfront.c: o Implement netfront_suspend(), a specialized suspend handler for the netfront driver. This routine simply disables the carrier so the driver is idle during system suspend processing. o Fix a leak when re-initializing LRO during a link reset. o In netif_release_tx_bufs(), when cleaning up the grant references for our TX ring, use gnttab_end_foreign_access_ref instead of attempting to grant the page again. o In netif_release_tx_bufs(), we do not track mbufs associated with mbuf chains, but instead just free each mbuf directly. Use m_free(), not m_freem(), to avoid double frees of mbufs. o Refactor some code to enhance clarity. Approved by: re MFC after: 1 week Notes: svn path=/head/; revision=225707
* Add suspend/resume support to the Xen blkfront driver.Justin T. Gibbs2011-09-212-46/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sponsored by: BQ Internet sys/dev/xen/blkfront/block.h: sys/dev/xen/blkfront/blkfront.c: Remove now unused blkif_vdev_t from the blkfront soft. sys/dev/xen/blkfront/blkfront.c: o In blkfront_suspend(), indicate the desire to suspend by changing the softc connected state to SUSPENDED, and then wait for any I/O pending on the remote peer to drain. Cancel suspend processing if I/O does not drain within 30 seconds. o Enable and update blkfront_resume(). Since I/O is drained prior to the suspension of the VM, the complicated recovery process performed by other Xen blkfront implementations is avoided. We simply tear down the connection to our old peer, and then re-connect. o In blkif_initialize(), fix a resource leak and botched return if we cannot allocate shadow memory for our requests. o In blkfront_backend_changed(), correct our response to the XenbusStateInitialised state. This state indicates that our backend peer has published sufficient data for blkfront to publish ring information and other XenStore data, not that a connection can occur. Blkfront now will only perform connection processing in response to the XenbusStateConnected state. This corrects an issue where blkfront connected before the backend was ready during resume processing. Approved by: re MFC after: 1 week Notes: svn path=/head/; revision=225705
* Properly handle suspend/resume events in the Xen deviceJustin T. Gibbs2011-09-201-9/+31

Sponsored by: BQ Internet sys/xen/xenbus/xenbusb.c: o In xenbusb_resume(), publish the state transition of the resuming device into XenbusStateIntiailising so that the remote peer can see it. Recording the state locally is not sufficient to trigger a re-connect sequence. o In xenbusb_resume(), defer new-bus resume processing until after the remote peer's XenStore address has been updated. The drivers may need to refer to this information during resume processing. sys/xen/xenbus/xenbusb_back.c: sys/xen/xenbus/xenbusb_front.c: Register xenbusb_resume() rather than bus_generic_resume() as the handler for device_resume events. sys/xen/xenstore/xenstore.c: o Fix grammer in a comment. o In xs_suspend(), pass suspend events on to the child devices (e.g. xenbusb_front/back, that are attached to the XenStore.

| | | | | | | | | | | | | | | | patch modifies makesyscalls.sh to prefix all of the non-compatibility calls (e.g. not linux_, freebsd32_) with sys_ and updates the kernel entry points and all places in the code that use them. It also fixes an additional name space collision between the kernel function psignal and the libc function of the same name by renaming the kernel psignal kern_psignal(). By introducing this change now we will ease future MFCs that change syscalls. Reviewed by: rwatson Approved by: re (bz) Notes: svn path=/head/; revision=225617
