* mi_switch(): clean up switch types and their usageMitchell Horne2023-02-092-4/+2
| | | | | | | | | | | | | | | | | | | Overall, this is a non-functional change, except for kernels built with SCHED_STATS. However, the switch types are useful for communicating the intent of the caller. 1. Ensure that every caller provides a type. In most cases, we upgrade the basic yield to sched_relinquish() aka SWT_RELINQUISH. 2. The case of sched_bind() is distinct, so add a new switch type SWT_BIND. 3. Remove the two unused types, SWT_PREEMPT and SWT_SLEEPQTIMO. 4. Remove SWT_NONE altogether and assert that callers always provide a type flag. 5. Reference the mi_switch(9) man page in the comments, as these flags will be documented there.

* dpaa: Don't assume the MDIO is on the same fman as the MACJustin Hibbits2022-11-282-31/+17
| | | | | The P5040 has the MDIO for FMAN2 on FMAN1 for some reason. Instead of trying to manually find the MDIO, use a real xref.
* dpaa: Don't probe disabled devicesJustin Hibbits2022-11-272-0/+6
| | | | Probing disabled devices just adds noise.
* dpaa: Use BUS_PASS_SUPPORTDEV for pqmdioJustin Hibbits2022-11-261-1/+1
| | | | | | | | BUS_PASS_SUPPORTDEV is semantically better than BUS_PASS_RESOURCE, since it's a support device for dtsec, so only needs probed before dtsec, not before interrupts. Suggested by: manu
* dpaa: Probe and attach pqmdio at BUS_PASS_RESOURCEJustin Hibbits2022-11-261-1/+2
| | | | | Avoid the fragile nature of depending on ordering of the devices in the FDT by forcing the MDIO driver to precede the DTSEC driver.
* dpaa: Account for MDIO device not being foundJustin Hibbits2022-11-261-0/+3
| | | | | | | | | It's possible the MDIO device hasn't been and attached, or is incorrect in the device tree so can't probe and attach. In this case, ofw_bus_find_child_device_by_phandle() will fail, and return NULL. Return an error from find_mdio() here to prevent the MAC from attaching, rather than worry about a NULL pointer dereference later on when accessing the PHY.
* dpaa: Go to cleanup exit point on fman attach errorJustin Hibbits2022-11-061-1/+1
| | | | | | | | | If fman_init() fails it can leave things in a state where it cannot attach at all in the future, because it would simply exit without tearing down everything that was already set up. Go to the exit point to clean up on error instead, so that it can try again later. MFC after: 1 week

| | | | | | | | | | | | | | | | | | Remove an old workaround that is no longer necessary since rS343824. There used to be a problem with FMan interrupts firing on multiple CPUS at the same time. This ended up being due to multicast interrupts being unsupported in the Freescale PIC (so instead of using a selection algorithm, it would do some unspecified action, such as interrupting multiple cpus at random.)

* [PowerPC] [Book-E] Fix dpaa interrupt binding.Brandon Bergren2020-02-251-2/+1
| | | | | | | | | | | | | | | | | | | | | | After the network epoch was added, we lost the ability to migrate the ithread in the middle of dispatch, as being in the network epoch will pin the current thread (for safety reasons.) Luckily, we don't actually have to do this workaround in the first place, as we can just bind it to the correct cpu when we preallocate it. Pass dev through to XX_PreallocAndBindIntr() and actually bind it to the cpu like it was supposed to in the first place, instad of leaving it floating and moving it to the correct cpu the first time it fires. This fixes panics while bringing up dtsec on my X5000. Reviewed by: jhibbits Sponsored by: Tag1 Consulting, Inc.

| | | | | | | | | | | | | | | | | | | switch over to opt-in instead of opt-out for epoch. Instead of IFF_NEEDSEPOCH, provide IFF_KNOWSEPOCH. If driver marks itself with IFF_KNOWSEPOCH, then ether_input() would not enter epoch when processing its packets. Now this will create recursive entrance in epoch in >90% network drivers, but will guarantee safeness of the transition. Mark several tested drivers as IFF_KNOWSEPOCH.

* schedlock 4/4Jeff Roberson2019-12-152-4/+2
| | | | | | | | | | | | | | | | | | | | | Don't hold the scheduler lock while doing context switches. Instead we unlock after selecting the new thread and switch within a spinlock section leaving interrupts and preemption disabled to prevent local concurrency. This means that mi_switch() is entered with the thread locked but returns without. This dramatically simplifies scheduler locking because we will not hold the schedlock while spinning on blocked lock in switch. This change has not been made to 4BSD but in principle it would be more straightforward.

| | | | | | | | | | | The BMan softc must exist when dtsec devices are created, else a NULL pointer is dereferenced. QMan likely as well. Until now, we have relied on order within the fdt parsing to attach correctly, but this obviously is not foolproof.

* Align OF_getencprop_alloc API with OF_getencprop and OF_getprop_allocOleksandr Tymoshenko2018-04-091-1/+1
| | | | | | | | | | | | | | | | | | | | | Change OF_getencprop_alloc semantics to be combination of malloc and OF_getencprop and return size of the property, not number of elements allocated. For the use cases where number of elements is preferred introduce OF_getencprop_alloc_multi helper function that copies semantics of OF_getencprop_alloc prior to this change. This is to make OF_getencprop_alloc and OF_getencprop_alloc_multi function signatures consistent with OF_getencprop_alloc and OF_getencprop_alloc_multi. Functionality-wise this patch is mostly rename of OF_getencprop_alloc to OF_getencprop_alloc_multi except two calls in ofw_bus_setup_iinfo where 1 was used as a block size.

* Allow bman-portals and qman-portals to attach to simple-busJustin Hibbits2017-12-142-7/+25
| | | | | | | | | Official Linux dts's put the individual portals under a simple-bus, rather than under a '*-portals' grouping. This adds a hack to permit that, which gets us closer to using stock device trees for DPAA-based devices. Notes: svn path=/head/; revision=326840
* Eliminate 1 XX_VirtToPhys() and 2 XX_PhysToVirt() calls from if_dtsec(4)Justin Hibbits2017-11-201-6/+6
| | | | | | | | | | | XX_VirtToPhys(), by way of pmap_kextract(), is an expensive operation. Profiling via dtrace during a series of iperf tests I found 16111 / 30432 stack frames were located in mmu_booke_kextract(), so eliminating this expensive call should improve performance slightly. XX_PhysToVirt() is not as expensive, but redundant calls in this context is wasteful. Notes: svn path=/head/; revision=326004

* Remove a singleton in the DPAA driver, to allow multiple fman instancesJustin Hibbits2017-11-014-37/+18
| | | | | | | | | | Some devices (P5040, P4080) have multiple frame managers in their DPAA subsystems. This was prevented by use of a softc singleton in the DPAA driver. Since if_dtsec(4) has moved to be a child of fman, it can access the fman device data via the parent object. Notes: svn path=/head/; revision=325255
* Make DPAA work in 64-bit modeJustin Hibbits2017-10-317-11/+205
| | | | | | | | | | Rework the dTSEC and FMan drivers to be more like a full bus relationship, so that dtsec can use bus_alloc_resource() instead of trying to handle the offset from the dts. This required taking some code from the sparc64 ebus driver to allow subdividing the fman region for the dTSEC devices. Notes: svn path=/head/; revision=325204

* Shorten list of arguments to mbuf external storage freeing function.Gleb Smirnoff2017-10-091-2/+4
| | | | | | | | | | | | | | | | | | | | All of these arguments are stored in m_ext, so there is no reason to pass them in the argument list. Not all functions need the second argument, some don't even need the first one. The second argument lives in next cache line, so not dereferencing it is a performance gain. This was discovered in sendfile(2), which will be covered by next commits. The second goal of this commit is to bring even more flexibility to m_ext mbufs, allowing to create more fields in m_ext, opaque to the generic mbuf code, and potentially set and dereferenced by subsystems.

* Make dpaa work with only slightly modified Linux device trees.Justin Hibbits2016-11-128-238/+137
| | | | | | | | | | | | | | | | | Linux has a slightly different device tree definition for DPAA than originally done in the FreeBSD driver. This changes the driver to be mostly compatible with the Linux device tree definitions. Currently the differences are: bman-portals: compatible = "fsl,bman-portals" (Linux is "simple-bus") qman-portals: compatible = "fsl,qman-portals" (Linux is "simple-bus") fman: compatible = "fsl,fman" (Linux is "simple-bus") The Linux device tree doesn't specify anything for rgmii in the mdio. This change still requires the device tree to specify the phy-handle, and doesn't yet support tbi. Notes: svn path=/head/; revision=308584

* Initialize the ofw_bus_devinfo on the portals to prevent a crash.Justin Hibbits2016-10-222-2/+2
| | | | | | | | | | If the device tree doesn't contain a cpu-handle field in any bman-portal or qman-portal, it will exit without setting up the devinfo, leaving it uninitialized. This will lead to attempts to free random memory, and ultimately panic. Notes: svn path=/head/; revision=307763
* Remove a hack requiring dtsec0 to always be enabled for mdio.Justin Hibbits2016-10-217-71/+282
| | | | | | | | | | | | | | | | | | | Instead replace it with a different hack, that turns fman into a simplebus subclass, and maps its children within its address space. Since all PHY communication is done through dtsec0's mdio space, the FDT contains a reference to the dtsec0 mdio handle in all nodes that need it. Instead of using Freescale's implementation for MII access, use our own (copied loosely from the eTSEC driver, and could possibly be merged eventually). This lets us access the registers directly rather than needing a full dtsec interface just to access the registers. Future directions will include turning fman into more of a simplebus, and not mapping the region and playing games. This will require changes to the dtsec driver to make it a child of fman, and possibly other drivers as well. Notes: svn path=/head/; revision=307696
