Existing transfer size "len" is either generated randomly or set to the
size of test_buf_size. In some cases we need to explicitly specify a
transfer size that is different from the buffer size and non aligned to
test the target device's ability to handle unaligned transfers.
This patch adds optional parameter "transfer_size" to allow setting
explicit transfer size for dma transfers.

Add parameter "alignment" to allow setting the address alignment
manually. Having the ability to configure address alignment from
user space adds new testing capabilities where different alignments can
be configured for testing without having to modify the dma device
alignment properties.
If configured, the alignment value will override the device alignment
property of the target device.

Add support for running tests on multiple channels simultaneously as the
driver currently limits to 1 channel per test run. This will add support
for stress testing DMA controllers with multi channel capabilities.
This is done by adding a callback function to the "channel" parameter
that registers the requested channel prior to the "run" parameter being
set to 1. Each time the "channel" parameter is populated with a new
dma channel, a new test is appended to the thread queue. Once the "run"
parameter is set to 1, the test will kick start all pending threads.

According to the documentation in include/uapi/asm-generic/ioctl.h,
_IOW means userspace is writing and kernel is reading, and
_IOR means userspace is reading and kernel is writing.
In case of these two ioctls, kernel is writing and userspace is reading,
so they have to be _IOR instead of _IOW.

Previously when a device was being emulated by an L1 guest for an L2
guest, that device couldn't then be passed through to an L3 guest. This
was because the L1 guest had no method for accessing L3 memory.
The hcall H_COPY_TOFROM_GUEST provides this access. Thus this setup for
passthrough can now be allowed.

quadrants 1 & 2
A guest cannot access quadrants 1 or 2 as this would result in an
exception. Thus introduce the hcall H_COPY_TOFROM_GUEST to be used by a
guest when it wants to perform an access to quadrants 1 or 2, for
example when it wants to access memory for one of its nested guests.
Also provide an implementation for the kvm-hv module.

Allow for a device which is being emulated at L0 (the host) for an L1
guest to be passed through to a nested (L2) guest.
The existing kvmppc_hv_emulate_mmio function can be used here. The main
challenge is that for a load the result must be stored into the L2 gpr,
not an L1 gpr as would normally be the case after going out to qemu to
complete the operation. This presents a challenge as at this point the
L2 gpr state has been written back into L1 memory.
To work around this we store the address in L1 memory of the L2 gpr
where the result of the load is to be stored and use the new io_gpr
value KVM_MMIO_REG_NESTED_GPR to indicate that this is a nested load for
which completion must be done when returning back into the kernel. Then
in kvmppc_complete_mmio_load() the resultant value is written into L1
memory at the location of the indicated L2 gpr.
Note that we don't currently let an L1 guest emulate a device for an L2
guest which is then passed through to an L3 guest.

The functions kvmppc_st and kvmppc_ld are used to access guest memory
from the host using a guest effective address. They do so by translating
through the process table to obtain a guest real address and then using
kvm_read_guest or kvm_write_guest to make the access with the guest real
address.
This method of access however only works for L1 guests and will give the
incorrect results for a nested guest.
We can however use the store_to_eaddr and load_from_eaddr kvmppc_ops to
perform the access for a nested guesti (and a L1 guest). So attempt this
method first and fall back to the old method if this fails and we aren't
running a nested guest.
At this stage there is no fall back method to perform the access for a
nested guest and this is left as a future improvement. For now we will
return to the nested guest and rely on the fact that a translation
should be faulted in before retrying the access.

The kvmppc_ops struct is used to store function pointers to kvm
implementation specific functions.
Introduce two new functions load_from_eaddr and store_to_eaddr to be
used to load from and store to a guest effective address respectively.
Also implement these for the kvm-hv module. If we are using the radix
mmu then we can call the functions to access quadrant 1 and 2.

The POWER9 radix mmu has the concept of quadrants. The quadrant number
is the two high bits of the effective address and determines the fully
qualified address to be used for the translation. The fully qualified
address consists of the effective lpid, the effective pid and the
effective address. This gives then 4 possible quadrants 0, 1, 2, and 3.
When accessing these quadrants the fully qualified address is obtained
as follows:
Quadrant | Hypervisor | Guest
--------------------------------------------------------------------------
| EA[0:1] = 0b00 | EA[0:1] = 0b00
0 | effLPID = 0 | effLPID = LPIDR
| effPID = PIDR | effPID = PIDR
--------------------------------------------------------------------------
| EA[0:1] = 0b01 |
1 | effLPID = LPIDR | Invalid Access
| effPID = PIDR |
--------------------------------------------------------------------------
| EA[0:1] = 0b10 |
2 | effLPID = LPIDR | Invalid Access
| effPID = 0 |
--------------------------------------------------------------------------
| EA[0:1] = 0b11 | EA[0:1] = 0b11
3 | effLPID = 0 | effLPID = LPIDR
| effPID = 0 | effPID = 0
--------------------------------------------------------------------------
In the Guest;
Quadrant 3 is normally used to address the operating system since this
uses effPID=0 and effLPID=LPIDR, meaning the PID register doesn't need to
be switched.
Quadrant 0 is normally used to address user space since the effLPID and
effPID are taken from the corresponding registers.
In the Host;
Quadrant 0 and 3 are used as above, however the effLPID is always 0 to
address the host.
Quadrants 1 and 2 can be used by the host to address guest memory using
a guest effective address. Since the effLPID comes from the LPID register,
the host loads the LPID of the guest it would like to access (and the
PID of the process) and can perform accesses to a guest effective
address.
This means quadrant 1 can be used to address the guest user space and
quadrant 2 can be used to address the guest operating system from the
hypervisor, using a guest effective address.
Access to the quadrants can cause a Hypervisor Data Storage Interrupt
(HDSI) due to being unable to perform partition scoped translation.
Previously this could only be generated from a guest and so the code
path expects us to take the KVM trampoline in the interrupt handler.
This is no longer the case so we modify the handler to call
bad_page_fault() to check if we were expecting this fault so we can
handle it gracefully and just return with an error code. In the hash mmu
case we still raise an unknown exception since quadrants aren't defined
for the hash mmu.

This adds code to flush the partition-scoped page tables for a radix
guest when dirty tracking is turned on or off for a memslot. Only the
guest real addresses covered by the memslot are flushed. The reason
for this is to get rid of any 2M PTEs in the partition-scoped page
tables that correspond to host transparent huge pages, so that page
dirtiness is tracked at a system page (4k or 64k) granularity rather
than a 2M granularity. The page tables are also flushed when turning
dirty tracking off so that the memslot's address space can be
repopulated with THPs if possible.
To do this, we add a new function kvmppc_radix_flush_memslot(). Since
this does what's needed for kvmppc_core_flush_memslot_hv() on a radix
guest, we now make kvmppc_core_flush_memslot_hv() call the new
kvmppc_radix_flush_memslot() rather than calling kvm_unmap_radix()
for each page in the memslot. This has the effect of fixing a bug in
that kvmppc_core_flush_memslot_hv() was previously calling
kvm_unmap_radix() without holding the kvm->mmu_lock spinlock, which
is required to be held.

For radix guests, this makes KVM map guest memory as individual pages
when dirty page logging is enabled for the memslot corresponding to the
guest real address. Having a separate partition-scoped PTE for each
system page mapped to the guest means that we have a separate dirty
bit for each page, thus making the reported dirty bitmap more accurate.
Without this, if part of guest memory is backed by transparent huge
pages, the dirty status is reported at a 2MB granularity rather than
a 64kB (or 4kB) granularity for that part, causing userspace to have
to transmit more data when migrating the guest.

mlxsw: spectrum_acl: Add Bloom filter support
Nir says:
Spectrum-2 uses Bloom filter to reduce the number of lookups in the
algorithmic TCAM (A-TCAM). HW performs multiple exact match lookups in a
given region using a key composed of { packet & mask, mask ID, region ID }.
The masks which are used in a region are called rule patterns or RP.
When such multiple masks are used, the A-TCAM region uses an eRP
(extended RP) table that describes which rule patterns are in use and
defines the order of the lookup. When eRP table is used in a region, one
way to reduce the number of the lookups is to consult a Bloom filter
before doing the lookup.
A Bloom filter is a space-efficient probabilistic data structure, on
which a query returns either "possibly in set" or "definitely not in
set". HW can skip a lookup if a query on the Bloom filter results a
"definitely not set" response. The mlxsw driver implements a "counting
filter" and when either a new entry is marked or the last entry is
removed it will update the HW. Update of this counting filter occurs
when rule is configured or deleted from a region.
Patch #1 adds PEABFE register which is used for setting Bloom filter
entries.
Patch #2 adds Bloom filter resources.
Patch #3 and patch #4 provide Bloom filter handling within mlxsw, by
adding initialization and logic for updating the Bloom bit vector in HW.
Patch #5 and patch #6 add required calls for Bloom filter update as part
of rule configuration flow.
Patch #7 handles transitions to and from eRP table. It uses a list to
keep A-TCAM rules in order to update rules in Bloom filter, in cases of
transitions from master mask based A-TCAM region to an eRP table based
region and vice versa.
Patch #8 removes a trick done on master RP index to a remaining RP,
since Bloom filter is updated on eRP transitions.
Finally, patch #9 activates Bloom filter mechanism in HW, by cancelling
the bypass that was configured before and the remaining three patches
are selftests that exercise the new code.

The eRP table is active when there is more than a single rule
pattern. It may be that the patterns are close enough and use delta
mechanism. Bloom filter index computation is based on the values of
{rule & mask, mask ID, region ID} where the rule delta bits must be
cleared.
Add a test that exercises Bloom filter with delta mechanism.
Configure rules within delta range and pass a packet which is
supposed to hit the correct rule.

Bloom filter is updated on transitions from a single rule pattern,
also called master RP, to eRP table and vice versa. Since rules are
being written to or deleted from the Bloom filter on such transitions,
it is not required to keep the same eRP bank ID for the master RP.
Change master RP index assignment so it will be assigned with zero.
This is consistent with the assignment of the first available spot
that is used for allocating eRP's indices.

Bloom filter update is required only for rules which reside on an
eRP. When the region has only a single rule pattern then eRP table
is not used, however insertion of another pattern would trigger a
move to an active eRP table so it is imperative to update the Bloom
filter with all previously configured rules.
Add a method that updates Bloom filter entries for all rules
currently configured in the region, on the event of a transition
from master mask to eRP, or vice versa. For that purpose, maintain
a list of all A-TCAM rules within mlxsw_sp_acl_atcam_region.

Spectrum-2 HW uses Bloom filter in order to skip lookups on specific
eRPs. It uses crc-16-Msbit-first calculation over a specific layout
of a rule's key fields combined with eRP ID as well as region ID.
Per potential lookup, iff the Bloom filter entry of the calculated
index is empty, then the lookup can be skipped. Hence, the mlxsw
driver should update the Bloom filter entry per each rule insertion
or deletion when rules are part of an eRP.
Add functions for adding and deleting entries in the Bloom filter.
In order to do so also add crc-16 computation based on the specific
Spectrum-2 polynomial and a function for encoding the crc-16 input
in the manner dictated by HW implementation.
