2020-11-13drm/amd/display: Extract 3rd plane from metadataBas Nieuwenhuizen
Now that we actually expose the right number of planes we get problems with modifier aware libva if we use an unsupported modifier. So this ensures that we as much as possible use a modifier that radeonsi can actually render to without going to extreme difficulty to synchronize an extra DCC metadata plane with implicit sync. Looking into the opaque metadata isn't ideal but this converts to something mainly for the purpose of the userspace driver and falls back properly if it isn't what we expect.

2020-11-13drm/amd/display: Set new format info for converted metadata.Bas Nieuwenhuizen
If we use DCC modifiers this can increase the number of planes from the initial 1 plane with metadata, so that we get a valid modifier from getfb2. Since the code didn't update the format_info getfb2 would only ever return 1 plane with a modifier for which userspace expects > 1. This moves the format lookup to amdgpu_display.c so we do not have issues when DC is not compiled.

2020-11-13drm/amd/display: Store gem objects for planes 1-3Bas Nieuwenhuizen
Also do the proper validation which was missed. Besides the missing validation, not storing the objects in the framebuffer led to wrong results in the getfb2 ioctl. Note that this should really have been done for multi-plane formats like NV12 already before modifiers landed.

2020-11-13drm/fourcc: add table describing AMD modifiers bit layoutSimon Ser
The table describes how each bit in the u64 value is used. Explicitly state which values a field can take if we have defines for them. Also add a note when a field isn't always populated. Forcing people to update the table when changing the bit layout should make it more obvious when there's a mistake, I hope. If we get to the point where the bit layout gets more complicated, it might be worth it to split the table into multiple tables (e.g. one for GFX8, one for GFX9+, and so on).

2020-11-13drm/fourcc: Fix modifier field mask for AMD modifiers.Bas Nieuwenhuizen
The DCC_MAX_COMPRESSED_BLOCK has to contain one of AMD_FMT_MOD_DCC_BLOCK_* and with 3 values this doesn't fit in 1 bit. Fix this cleanly while it is only in drm-next.

This patch fixes nearly 400 warnings! These structures are too widely used in too many varying configurations to be split-up into different headers or moved into source files. Instead, we'll mark them as __maybe_unused which tells the compiler that we're aware they're being included into source files which do not make use of them - but we've looked into it, and it's okay.

2020-11-13net: Exempt multicast addresses from five-second neighbor lifetimeJeff Dike
Commit 58956317c8de ("neighbor: Improve garbage collection") guarantees neighbour table entries a five-second lifetime. Processes which make heavy use of multicast can fill the neighour table with multicast addresses in five seconds. At that point, neighbour entries can't be GC-ed because they aren't five seconds old yet, the kernel log starts to fill up with "neighbor table overflow!" messages, and sends start to fail. This patch allows multicast addresses to be thrown out before they've lived out their five seconds. This makes room for non-multicast addresses and makes messages to all addresses more reliable in these circumstances.

This is true for data reservation and mostly true for metadata. Since data space reservation always happens before we start a transaction, and for most metadata operation we reserve space in start_transaction(). But there is an exception, btrfs_delayed_inode_reserve_metadata(). It holds a transaction handle, while still trying to reserve extra metadata space. When we hit EDQUOT inside btrfs_delayed_inode_reserve_metadata(), we will join current transaction and commit, while we still have transaction handle from qgroup code. [FIX] Let's check current->journal before we join the transaction. If current->journal is unset or BTRFS_SEND_TRANS_STUB, it means we are not holding a transaction, thus are able to join and then commit transaction. If current->journal is a valid transaction handle, we avoid committing transaction and just end it This is less effective than committing current transaction, as it won't free metadata reserved space, but we may still free some data space before new data writes.

2020-11-13btrfs: fix missing delalloc new bit for new delalloc rangesFilipe Manana
When doing a buffered write, through one of the write family syscalls, we look for ranges which currently don't have allocated extents and set the 'delalloc new' bit on them, so that we can report a correct number of used blocks to the stat(2) syscall until delalloc is flushed and ordered extents complete. However there are a few other places where we can do a buffered write against a range that is mapped to a hole (no extent allocated) and where we do not set the 'new delalloc' bit. Those places are: - Doing a memory mapped write against a hole; - Cloning an inline extent into a hole starting at file offset 0; - Calling btrfs_cont_expand() when the i_size of the file is not aligned to the sector size and is located in a hole. For example when cloning to a destination offset beyond EOF. So after such cases, until the corresponding delalloc range is flushed and the respective ordered extents complete, we can report an incorrect number of blocks used through the stat(2) syscall. In some cases we can end up reporting 0 used blocks to stat(2), which is a particular bad value to report as it may mislead tools to think a file is completely sparse when its i_size is not zero, making them skip reading any data, an undesired consequence for tools such as archivers and other backup tools, as reported a long time ago in the following thread (and other past threads): https://lists.gnu.org/archive/html/bug-tar/2016-07/msg00001.html Example reproducer: $ cat reproducer.sh #!/bin/bash MNT=/mnt/sdi DEV=/dev/sdi mkfs.btrfs -f $DEV > /dev/null # mkfs.xfs -f $DEV > /dev/null # mkfs.ext4 -F $DEV > /dev/null # mkfs.f2fs -f $DEV > /dev/null mount $DEV $MNT xfs_io -f -c "truncate 64K" \ -c "mmap -w 0 64K" \ -c "mwrite -S 0xab 0 64K" \ -c "munmap" \ $MNT/foo blocks_used=$(stat -c %b $MNT/foo) echo "blocks used: $blocks_used" if [ $blocks_used -eq 0 ]; then echo "ERROR: blocks used is 0" fi umount $DEV $ ./reproducer.sh blocks used: 0 ERROR: blocks used is 0 So move the logic that decides to set the 'delalloc bit' bit into the function btrfs_set_extent_delalloc(), since that is what we use for all those missing cases as well as for the cases that currently work well. This change is also preparatory work for an upcoming patch that fixes other problems related to tracking and reporting the number of bytes used by an inode.

2020-11-13arm64: implement CPPC FFH support using AMUsIonela Voinescu
If Activity Monitors (AMUs) are present, two of the counters can be used to implement support for CPPC's (Collaborative Processor Performance Control) delivered and reference performance monitoring functionality using FFH (Functional Fixed Hardware). Given that counters for a certain CPU can only be read from that CPU, while FFH operations can be called from any CPU for any of the CPUs, use smp_call_function_single() to provide the requested values. Therefore, depending on the register addresses, the following values are returned: - 0x0 (DeliveredPerformanceCounterRegister): AMU core counter - 0x1 (ReferencePerformanceCounterRegister): AMU constant counter The use of Activity Monitors is hidden behind the generic cpu_read_{corecnt,constcnt}() functions. Read functionality for these two registers represents the only current FFH support for CPPC. Read operations for other register values or write operation for all registers are unsupported. Therefore, keep CPPC's FFH unsupported if no CPUs have valid AMU frequency counters. For this purpose, the get_cpu_with_amu_feat() is introduced.
