Based on hw/usb/hcd-ehci.c and hw/usb/hcd-ohci.c. Note that to use this with the dwc-otg driver in the Raspbian kernel, you must pass the option "dwc_otg.fiq_fsm_enable=0" on the kernel command line. Emulation of slave mode and of descriptor-DMA mode has not been implemented yet. These modes are seldom used. I have used some on-line sources of information while developing this emulation, including: http://www.capital-micro.com/PDF/CME-M7_Family_User_Guide_EN.pdf which has a pretty complete description of the controller starting on page 370. https://sourceforge.net/p/wive-ng/wive-ng-mt/ci/master/tree/docs/DataSheets/RT3050_5x_V2.0_081408_0902.pdf which has a description of the controller registers starting on page 130. Thanks to Felippe Mathieu-Daude for providing a cleaner method of implementing the memory regions for the controller registers.

In QEMU, we have 3 kinds of cpus regarding cryptographic instructions: + no support + cortex-a57/a72: cryptographic extension is optional, floating-point/neon is not. + cortex-a53: crytographic extension is optional as well as floating-point/neon. But cryptographic requires floating-point/neon support. Therefore we can safely clear the ISAR fields when neon is disabled. Note that other Arm cpus seem to follow this. For example cortex-a55 is like cortex-a53 and cortex-a76/cortex-a710 are like cortex-a57/a72.

The description of the equivalent SMMU feature in the SMMU specification (IHI0070D.b section 3.21.1) is perhaps a bit more detailed and includes some example valid implementation choices. (The SMMU version of this feature is slightly tighter than the CPU version: the CPU is permitted to raise TLB Conflict aborts in some situations that the SMMU may not. This doesn't matter for QEMU because we don't want to do TLB Conflict aborts anyway.) The informal summary of FEAT_BBM is that it is about permitting an OS to switch a range of memory between "covered by a huge page" and "covered by a sequence of normal pages" without having to engage in the 'break-before-make' dance that has traditionally been necessary. The 'break-before-make' sequence is: * replace the old translation table entry with an invalid entry * execute a DSB insn * execute a broadcast TLB invalidate insn * execute a DSB insn * write the new translation table entry * execute a DSB insn The point of this is to ensure that no TLB can simultaneously contain TLB entries for the old and the new entry, which would traditionally be UNPREDICTABLE (allowing the CPU to generate a TLB Conflict fault or to use a random mishmash of values from the old and the new entry). FEAT_BBM level 2 says "for the specific case where the only thing that changed is the size of the block, the TLB is guaranteed not to do weird things even if there are multiple entries for an address", which means that software can now do: * replace old translation table entry with new entry * DSB * broadcast TLB invalidate * DSB As the SMMU spec notes, valid ways to do this include: * if there are multiple entries in the TLB for an address, choose one of them and use it, ignoring the others * if there are multiple entries in the TLB for an address, throw them all out and do a page table walk to get a new one QEMU's page table walk implementation for Arm CPUs already meets the requirements for FEAT_BBM level 2. When we cache an entry in our TCG TLB, we do so only for the specific (non-huge) page that the address is in, and there is no way for the TLB data structure to ever have more than one TLB entry for that page. (We handle huge pages only in that we track what part of the address space is covered by huge pages so that a TLB invalidate operation for an address in a huge page results in an invalidation of the whole TLB.) We ignore the Contiguous bit in page table entries, so we don't have to do anything for the parts of FEAT_BBM that deal with changis to the Contiguous bit. FEAT_BBM level 2 also requires that the nT bit in block descriptors must be ignored; since commit 39a1fd25287f5dece5 we do this. It's therefore safe for QEMU to advertise FEAT_BBM level 2 by setting ID_AA64MMFR2_EL1.BBM to 2.

(This is particularly important for the SMMU, because devices performing I/O through an SMMU are less likely to be able to cope with the window in the sequence where an access results in a translation fault.) The SMMU spec explicitly notes that one of the valid ways to be a BBM level 2 compliant implementation is: * if there are multiple entries in the TLB for an address, choose one of them and use it, ignoring the others Our SMMU TLB implementation (unlike our CPU TLB) does allow multiple TLB entries for an address, because the translation table level is part of the SMMUIOTLBKey, and so our IOTLB hashtable can include entries for the same address where the leaf was at different levels (i.e. both hugepage and normal page). Our TLB lookup implementation in smmu_iotlb_lookup() will always find the entry with the lowest level (i.e. it prefers the hugepage over the normal page) and ignore any others. TLB invalidation correctly removes all TLB entries matching the specified address or address range (unless the guest specifies the leaf level explicitly, in which case it gets what it asked for). So we can validly advertise support for BBML level 2. Note that we still can't yet advertise ourselves as an SMMU v3.2, because v3.2 requires support for the S2FWB feature, which we don't yet implement.
