If we configure section consist of multiple segments, foreground GC will
do the garbage collection with following approach:
for each segment in victim section
blk_start_plug
for each valid block in segment
write out by OPU method
submit bio cache <---
blk_finish_plug <---
There are two issue:
1) for most of the time, 'submit bio cache' will break the merging in
current bio buffer from writes of next segments, making a smaller bio
submitting.
2) block plug only cover IO submitting in one segment, which reduce
opportunity of merging IOs in plug with multiple segments.
So refactor the code as below structure to strive for biggest
opportunity of merging IOs:
blk_start_plug
for each segment in victim section
for each valid block in segment
write out by OPU method
submit bio cache
blk_finish_plug
Test method:
1. mkfs.f2fs -s 8 /dev/sdX
2. touch 32 files
3. write 2M data into each file
4. punch 1.5M data from offset 0 for each file
5. trigger foreground gc through ioctl
Before patch, there are totoally 40 bios submitted.

When testing f2fs with xfstest, generic/251 is stuck for long time,
the case uses below serials to obtain fresh released space in device,
in order to prepare for following fstrim test.
1. rm -rf /mnt/dir
2. mkdir /mnt/dir/
3. cp -axT `pwd`/ /mnt/dir/
4. goto 1
During preparing step, all nat entries will be cached in nat cache,
most of them are dirty entries with invalid blkaddr, which means
nodes related to these entries have been truncated, and they could
be reused after the dirty entries been checkpointed.
However, there was no checkpoint been triggered, so nid allocators
(e.g. mkdir, creat) will run into long journey of iterating all NAT
pages, looking for free nids in alloc_nid->build_free_nids.
Here, in f2fs_balance_fs_bg we give another chance to do checkpoint
to flush nat entries for reusing them in free nid cache when dirty
entry count exceeds 10% of max count.

Currently we maintain perfect LRU list by moving entry to the tail of
the list when it gets used. However these operations on cache-global
list are relatively expensive.
In this patch we switch to lazy updates of LRU list. Whenever entry gets
used, we set a referenced bit in it. When reclaiming entries, we give
referenced entries another round in the LRU. Since the list is not a
real LRU anymore, rename it to just 'list'.
In my testing this logic gives about 30% boost to workloads with mostly
unique xattr blocks (e.g. xattr-bench with 10 files and 10000 unique
xattr values).

Provide read-only access to PCI config space of the PCI host bridge

Typically config space for a device is mapped out into capability
specific handlers and unassigned space. The latter allows direct
read/write access to config space. Sometimes we know about registers
living in this void space and would like an easy way to virtualize
them, similar to how BAR registers are managed. To do this, create
one more pseudo (fake) PCI capability to be handled as purely virtual
space. Reads and writes are serviced entirely from virtual config
space.

Add support for additional regions with indexes started after the
already defined fixed regions. Device specific code can register
these regions with the new vfio_pci_register_dev_region() function.
The ops structure per region currently only includes read/write
access and a release function, allowing automatic cleanup when the
device is closed. mmap support is only missing here because it's
not needed by the first user queued for this support.
Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
To this point vfio has only provided an interface to the user that
allows them to determine the number of regions and specifics about
each region. What the region represents is left to the vfio bus
driver. vfio-pci chooses to use fixed indexes for fixed resources,
index 0 is BAR0, 1 is BAR1,... 7 is config space, etc. This works
pretty well since all PCI devices have these regions, even if they
don't necessarily populate all of them. Then we start to add things
like VGA, which only certain device even support. We added this the
same way, but now we've wasted a region index, and due to our offset
implementation the corresponding address space, for all devices.
Rather than continuing that process, let's try to make regions self
describing by including a capability that defines their type. For
vfio-pci we'll make the current VFIO_PCI_NUM_REGIONS fixed, defining
the end of the static indexes and the beginning of self describing
regions.

vfio-pci has never allowed the user to directly mmap the MSI-X vector
table, but we've always relied on implicit knowledge of the user that
they cannot do this. Now that we have capability chains that we can
expose in the region info ioctl and a sparse mmap capability that
represents the sub-areas within the region that can be mmap'd, we can
make the mmap constraints more explicit.
Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
We can't always support mmap across an entire device region, for
example we deny mmaps covering the MSI-X table of PCI devices, but
we don't really have a way to report it. We expect the user to
implicitly know this restriction. We also can't split the region
because vfio-pci defines an API with fixed region index to BAR
number mapping. We therefore define a new capability which lists
areas within the region that may be mmap'd. In addition to the
MSI-X case, this potentially enables in-kernel emulation and
extensions to devices.

Allow sub-modules to easily reallocate a buffer for managing
capability chains for info ioctls.
Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
We have a few cases where we need to extend the data returned from the
INFO ioctls in VFIO. For instance we already have devices exposed
through vfio-pci where VFIO_DEVICE_GET_REGION_INFO reports the region
as mmap-capable, but really only supports sparse mmaps, avoiding the
MSI-X table. If we wanted to provide in-kernel emulation or extended
functionality for devices, we'd also want the ability to tell the
user not to mmap various regions, rather than forcing them to figure
it out on their own.
Another example is VFIO_IOMMU_GET_INFO. We'd really like to expose
the actual IOVA capabilities of the IOMMU rather than letting the
user assume the address space they have available to them. We could
add IOVA base and size fields to struct vfio_iommu_type1_info, but
what if we have multiple IOVA ranges. For instance x86 uses a range
of addresses at 0xfee00000 for MSI vectors. These typically are not
available for standard DMA IOVA mappings and splits our available IOVA
space into two ranges. POWER systems have both an IOVA window below
4G as well as dynamic data window which they can use to remap all of
guest memory.
Representing variable sized arrays within a fixed structure makes it
very difficult to parse, we'd therefore like to put this data beyond
fixed fields within the data structures. One way to do this is to
emulate capabilities in PCI configuration space. A new flag indciates
whether capabilties are supported and a new fixed field reports the
offset of the first entry. Users can then walk the chain to find
capabilities, adding capabilities does not require additional fields
in the fixed structure, and parsing variable sized data becomes
trivial.
This patch outlines the theory and base header structure, which
should be shared by all future users.
Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
Consider an IOMMU to be an API rather than an implementation, we might
have multiple implementations supporting the same API, so try another
if one fails. The expectation here is that we'll really only have
one implementation per device type. For instance the existing type1
driver works with any PCI device where the IOMMU API is available. A
vGPU vendor may have a virtual PCI device which provides DMA isolation
and mapping through other mechanisms, but can re-use userspaces that
make use of the type1 VFIO IOMMU API. This allows that to work.

Signed versus unsigned comparisons are implicitly cast to unsigned,
which result in a couple possible overflows. For instance (start +
count) might overflow and wrap, getting through our validation test.
Also when unwinding setup, -1 being compared as unsigned doesn't
produce the intended stop condition. Fix both of these and also fix
vfio_msi_set_vector_signal() to validate parameters before using the
vector index, though none of the callers should pass bad indexes
anymore.

This reverts commit 858d588156.
Joachim reports that this commit breaks lpc18xx boot. This is
because the hardware has circular clk topology where PLLs can
feed into dividers and the same dividers can feed into the PLLs.
The hardware is designed this way so that you can choose to put
the divider before the PLL or after the PLL depending on what you
configure to be the parent of the divider and what you configure
to be the parent of the PLL.
So let's drop this patch for now because we have hardware that
actually has loops. A future patch could check for circular
parents when we change parents and fail the switch, but that's
probably best left to some debugging Kconfig option so that we
don't suffer the sanity checking cost all the time.
