+This document describes the requirement from hardware for PCI MMIO resource
+sizing and assignment on PowerKVM and how generic PCI code handles this
+requirement. The first two sections describe the concepts of Partitionable
+Endpoints and the implementation on P8 (IODA2). The next two sections talks
+about considerations on enabling SRIOV on IODA2.
+
+1. Introduction to Partitionable Endpoints
+
+A Partitionable Endpoint (PE) is a way to group the various resources
+associated with a device or a set of devices to provide isolation between
+partitions (i.e., filtering of DMA, MSIs etc.) and to provide a mechanism
+to freeze a device that is causing errors in order to limit the possibility
+of propagation of bad data.
+
+There is thus, in HW, a table of PE states that contains a pair of "frozen"
+state bits (one for MMIO and one for DMA, they get set together but can be
+cleared independently) for each PE.
+
+When a PE is frozen, all stores in any direction are dropped and all loads
+return all 1's value. MSIs are also blocked. There's a bit more state that
+captures things like the details of the error that caused the freeze etc., but
+that's not critical.
+
+The interesting part is how the various PCIe transactions (MMIO, DMA, ...)
+are matched to their corresponding PEs.
+
+The following section provides a rough description of what we have on P8
+(IODA2). Keep in mind that this is all per PHB (PCI host bridge). Each PHB
+is a completely separate HW entity that replicates the entire logic, so has
+its own set of PEs, etc.
+
+2. Implementation of Partitionable Endpoints on P8 (IODA2)
+
+P8 supports up to 256 Partitionable Endpoints per PHB.
+
+ * Inbound
+
+ For DMA, MSIs and inbound PCIe error messages, we have a table (in
+ memory but accessed in HW by the chip) that provides a direct
+ correspondence between a PCIe RID (bus/dev/fn) with a PE number.
+ We call this the RTT.
+
+ - For DMA we then provide an entire address space for each PE that can
+ contain two "windows", depending on the value of PCI address bit 59.
+ Each window can be configured to be remapped via a "TCE table" (IOMMU
+ translation table), which has various configurable characteristics
+ not described here.
+
+ - For MSIs, we have two windows in the address space (one at the top of
+ the 32-bit space and one much higher) which, via a combination of the
+ address and MSI value, will result in one of the 2048 interrupts per
+ bridge being triggered. There's a PE# in the interrupt controller
+ descriptor table as well which is compared with the PE# obtained from
+ the RTT to "authorize" the device to emit that specific interrupt.
+
+ - Error messages just use the RTT.
+
+ * Outbound. That's where the tricky part is.
+
+ Like other PCI host bridges, the Power8 IODA2 PHB supports "windows"
+ from the CPU address space to the PCI address space. There is one M32
+ window and sixteen M64 windows. They have different characteristics.
+ First what they have in common: they forward a configurable portion of
+ the CPU address space to the PCIe bus and must be naturally aligned
+ power of two in size. The rest is different:
+
+ - The M32 window:
+
+ * Is limited to 4GB in size.
+
+ * Drops the top bits of the address (above the size) and replaces
+ them with a configurable value. This is typically used to generate
+ 32-bit PCIe accesses. We configure that window at boot from FW and
+ don't touch it from Linux; it's usually set to forward a 2GB
+ portion of address space from the CPU to PCIe
+ 0x8000_0000..0xffff_ffff. (Note: The top 64KB are actually
+ reserved for MSIs but this is not a problem at this point; we just
+ need to ensure Linux doesn't assign anything there, the M32 logic
+ ignores that however and will forward in that space if we try).
+
+ * It is divided into 256 segments of equal size. A table in the chip
+ maps each segment to a PE#. That allows portions of the MMIO space
+ to be assigned to PEs on a segment granularity. For a 2GB window,
+ the segment granularity is 2GB/256 = 8MB.
+
+ Now, this is the "main" window we use in Linux today (excluding
+ SR-IOV). We basically use the trick of forcing the bridge MMIO windows
+ onto a segment alignment/granularity so that the space behind a bridge
+ can be assigned to a PE.
+
+ Ideally we would like to be able to have individual functions in PEs
+ but that would mean using a completely different address allocation
+ scheme where individual function BARs can be "grouped" to fit in one or
+ more segments.
+
+ - The M64 windows:
+
+ * Must be at least 256MB in size.
+
+ * Do not translate addresses (the address on PCIe is the same as the
+ address on the PowerBus). There is a way to also set the top 14
+ bits which are not conveyed by PowerBus but we don't use this.
+
+ * Can be configured to be segmented. When not segmented, we can
+ specify the PE# for the entire window. When segmented, a window
+ has 256 segments; however, there is no table for mapping a segment
+ to a PE#. The segment number *is* the PE#.
+
+ * Support overlaps. If an address is covered by multiple windows,
+ there's a defined ordering for which window applies.
+
+ We have code (fairly new compared to the M32 stuff) that exploits that
+ for large BARs in 64-bit space:
+
+ We configure an M64 window to cover the entire region of address space
+ that has been assigned by FW for the PHB (about 64GB, ignore the space
+ for the M32, it comes out of a different "reserve"). We configure it
+ as segmented.
+
+ Then we do the same thing as with M32, using the bridge alignment
+ trick, to match to those giant segments.
+
+ Since we cannot remap, we have two additional constraints:
+
+ - We do the PE# allocation *after* the 64-bit space has been assigned
+ because the addresses we use directly determine the PE#. We then
+ update the M32 PE# for the devices that use both 32-bit and 64-bit
+ spaces or assign the remaining PE# to 32-bit only devices.
+
+ - We cannot "group" segments in HW, so if a device ends up using more
+ than one segment, we end up with more than one PE#. There is a HW
+ mechanism to make the freeze state cascade to "companion" PEs but
+ that only works for PCIe error messages (typically used so that if
+ you freeze a switch, it freezes all its children). So we do it in
+ SW. We lose a bit of effectiveness of EEH in that case, but that's
+ the best we found. So when any of the PEs freezes, we freeze the
+ other ones for that "domain". We thus introduce the concept of
+ "master PE" which is the one used for DMA, MSIs, etc., and "secondary
+ PEs" that are used for the remaining M64 segments.
+
+ We would like to investigate using additional M64 windows in "single
+ PE" mode to overlay over specific BARs to work around some of that, for
+ example for devices with very large BARs, e.g., GPUs. It would make
+ sense, but we haven't done it yet.
+
+3. Considerations for SR-IOV on PowerKVM
+
+ * SR-IOV Background
+
+ The PCIe SR-IOV feature allows a single Physical Function (PF) to
+ support several Virtual Functions (VFs). Registers in the PF's SR-IOV
+ Capability control the number of VFs and whether they are enabled.
+
+ When VFs are enabled, they appear in Configuration Space like normal
+ PCI devices, but the BARs in VF config space headers are unusual. For
+ a non-VF device, software uses BARs in the config space header to
+ discover the BAR sizes and assign addresses for them. For VF devices,
+ software uses VF BAR registers in the *PF* SR-IOV Capability to
+ discover sizes and assign addresses. The BARs in the VF's config space
+ header are read-only zeros.
+
+ When a VF BAR in the PF SR-IOV Capability is programmed, it sets the
+ base address for all the corresponding VF(n) BARs. For example, if the
+ PF SR-IOV Capability is programmed to enable eight VFs, and it has a
+ 1MB VF BAR0, the address in that VF BAR sets the base of an 8MB region.
+ This region is divided into eight contiguous 1MB regions, each of which
+ is a BAR0 for one of the VFs. Note that even though the VF BAR
+ describes an 8MB region, the alignment requirement is for a single VF,
+ i.e., 1MB in this example.
+
+ There are several strategies for isolating VFs in PEs:
+
+ - M32 window: There's one M32 window, and it is split into 256
+ equally-sized segments. The finest granularity possible is a 256MB
+ window with 1MB segments. VF BARs that are 1MB or larger could be
+ mapped to separate PEs in this window. Each segment can be
+ individually mapped to a PE via the lookup table, so this is quite
+ flexible, but it works best when all the VF BARs are the same size. If
+ they are different sizes, the entire window has to be small enough that
+ the segment size matches the smallest VF BAR, which means larger VF
+ BARs span several segments.
+
+ - Non-segmented M64 window: A non-segmented M64 window is mapped entirely
+ to a single PE, so it could only isolate one VF.
+
+ - Single segmented M64 windows: A segmented M64 window could be used just
+ like the M32 window, but the segments can't be individually mapped to
+ PEs (the segment number is the PE#), so there isn't as much
+ flexibility. A VF with multiple BARs would have to be in a "domain" of
+ multiple PEs, which is not as well isolated as a single PE.
+
+ - Multiple segmented M64 windows: As usual, each window is split into 256
+ equally-sized segments, and the segment number is the PE#. But if we
+ use several M64 windows, they can be set to different base addresses
+ and different segment sizes. If we have VFs that each have a 1MB BAR
+ and a 32MB BAR, we could use one M64 window to assign 1MB segments and
+ another M64 window to assign 32MB segments.
+
+ Finally, the plan to use M64 windows for SR-IOV, which will be described
+ more in the next two sections. For a given VF BAR, we need to
+ effectively reserve the entire 256 segments (256 * VF BAR size) and
+ position the VF BAR to start at the beginning of a free range of
+ segments/PEs inside that M64 window.
+
+ The goal is of course to be able to give a separate PE for each VF.
+
+ The IODA2 platform has 16 M64 windows, which are used to map MMIO
+ range to PE#. Each M64 window defines one MMIO range and this range is
+ divided into 256 segments, with each segment corresponding to one PE.
+
+ We decide to leverage this M64 window to map VFs to individual PEs, since
+ SR-IOV VF BARs are all the same size.
+
+ But doing so introduces another problem: total_VFs is usually smaller
+ than the number of M64 window segments, so if we map one VF BAR directly
+ to one M64 window, some part of the M64 window will map to another
+ device's MMIO range.
+
+ IODA supports 256 PEs, so segmented windows contain 256 segments, so if
+ total_VFs is less than 256, we have the situation in Figure 1.0, where
+ segments [total_VFs, 255] of the M64 window may map to some MMIO range on
+ other devices:
+
+ 0 1 total_VFs - 1
+ +------+------+- -+------+------+
+ | | | ... | | |
+ +------+------+- -+------+------+
+
+ VF(n) BAR space
+
+ 0 1 total_VFs - 1 255
+ +------+------+- -+------+------+- -+------+------+
+ | | | ... | | | ... | | |
+ +------+------+- -+------+------+- -+------+------+
+
+ M64 window
+
+ Figure 1.0 Direct map VF(n) BAR space
+
+ Our current solution is to allocate 256 segments even if the VF(n) BAR
+ space doesn't need that much, as shown in Figure 1.1:
+
+ 0 1 total_VFs - 1 255
+ +------+------+- -+------+------+- -+------+------+
+ | | | ... | | | ... | | |
+ +------+------+- -+------+------+- -+------+------+
+
+ VF(n) BAR space + extra
+
+ 0 1 total_VFs - 1 255
+ +------+------+- -+------+------+- -+------+------+
+ | | | ... | | | ... | | |
+ +------+------+- -+------+------+- -+------+------+
+
+ M64 window
+
+ Figure 1.1 Map VF(n) BAR space + extra
+
+ Allocating the extra space ensures that the entire M64 window will be
+ assigned to this one SR-IOV device and none of the space will be
+ available for other devices. Note that this only expands the space
+ reserved in software; there are still only total_VFs VFs, and they only
+ respond to segments [0, total_VFs - 1]. There's nothing in hardware that
+ responds to segments [total_VFs, 255].
+
+4. Implications for the Generic PCI Code
+
+The PCIe SR-IOV spec requires that the base of the VF(n) BAR space be
+aligned to the size of an individual VF BAR.
+
+In IODA2, the MMIO address determines the PE#. If the address is in an M32
+window, we can set the PE# by updating the table that translates segments
+to PE#s. Similarly, if the address is in an unsegmented M64 window, we can
+set the PE# for the window. But if it's in a segmented M64 window, the
+segment number is the PE#.
+
+Therefore, the only way to control the PE# for a VF is to change the base
+of the VF(n) BAR space in the VF BAR. If the PCI core allocates the exact
+amount of space required for the VF(n) BAR space, the VF BAR value is fixed
+and cannot be changed.
+
+On the other hand, if the PCI core allocates additional space, the VF BAR
+value can be changed as long as the entire VF(n) BAR space remains inside
+the space allocated by the core.
+
+Ideally the segment size will be the same as an individual VF BAR size.
+Then each VF will be in its own PE. The VF BARs (and therefore the PE#s)
+are contiguous. If VF0 is in PE(x), then VF(n) is in PE(x+n). If we
+allocate 256 segments, there are (256 - numVFs) choices for the PE# of VF0.
+
+If the segment size is smaller than the VF BAR size, it will take several
+segments to cover a VF BAR, and a VF will be in several PEs. This is
+possible, but the isolation isn't as good, and it reduces the number of PE#
+choices because instead of consuming only numVFs segments, the VF(n) BAR
+space will consume (numVFs * n) segments. That means there aren't as many
+available segments for adjusting base of the VF(n) BAR space.
