IPA version 4.9 and later use a different layout of some fields found in the COMP_CFG register. Define arbitration_lock_disable_encoded(), and use it to encode a value into the ATOMIC_FETCHER_ARB_LOCK_DIS field based on the IPA version. And define full_flush_rsc_closure_en_encoded() to encode a value into the FULL_FLUSH_WAIT_RSC_CLOSE_EN field based on the IPA version. The values of these fields are neither modified nor extracted by current code, but this patch makes this possible for all supported versions. Fix a mistaken comment above ipa_hardware_config_comp() intended to describe the purpose for the register. Signed-off-by:

Add and update IPA register definitions. Extend these definitions to incorporate a fairly small number of new symbols (register offsets and fields) to support IPA v3.0, v3.1, v3.5, v4.0, v4.1, v4.7, 4.9, and v4.11, and have the comments reflect when they are valid. None of the added symbols require changes elsewhere in the code. Update rsrc_grp_encoded() to support these other IPA versions. Add kerneldoc comments for the IPA IRQ numbers and sequencer type. Fix a few spots where the version check should be less restrictive (missed by an earlier patch). Signed-off-by:

Jakub Kicinski says: ==================== ethtool: clarify the ethtool FEC interface Our FEC configuration interface is one of the more confusing. It also lacks any error checking in the core. This certainly shows in the varying implementations across the drivers. Improve the documentation and add most basic checks. Sadly, it's probably too late now to try to enforce much more uniformity. Any thoughts & suggestions welcome. Next step is to add netlink for FEC, then stats. ==================== Signed-off-by: -
Jakub Kicinski authored
The definition of the FEC driver interface is quite unclear. Improve the documentation. This is based on current driver and user space code, as well as the discussions about the interface: RFC v1 (24 Oct 2016): https://lore.kernel.org/netdev/1477363849-36517-1-git-send-email-vidya@cumulusnetworks.com/ - this version has the autoneg field - no active_fec field - none vs off confusion is already present RFC v2 (10 Feb 2017): https://lore.kernel.org/netdev/1486727004-11316-1-git-send-email-vidya@cumulusnetworks.com/ - autoneg removed - active_fec added v1 (10 Feb 2017): https://lore.kernel.org/netdev/1486751311-42019-1-git-send-email-vidya@cumulusnetworks.com/ - no changes in the code v1 (24 Jun 2017): https://lore.kernel.org/netdev/1498331985-8525-1-git-send-email-roopa@cumulusnetworks.com/ - include in tree user v2 (27 Jul 2017): https://lore.kernel.org/netdev/1501199248-24695-1-git-send-email-roopa@cumulusnetworks.com/Signed-off-by:

Reject NONE on set, this mode means device does not support FEC so it's a little out of place in the set interface. This should be safe to do - user space ethtool does not allow the use of NONE on set. A few drivers treat it the same as OFF, but none use it instead of OFF. Similarly reject an empty FEC mask. The common user space tool will not send such requests and most drivers correctly reject it already. Signed-off-by:

struct ethtool_fecparam::active_fec is a GET-only field, all in-tree drivers correctly ignore it on SET. Clear the field on SET to avoid any confusion. Again, we can't reject non-zero now since ethtool user space does not zero-init the param correctly. Signed-off-by:

struct ethtool_fecparam::reserved is never looked at by the core. Make sure it's actually 0. Unfortunately we can't return an error because old ethtool doesn't zero-initialize the structure for SET. On GET we can be more verbose, there are no in tree (ab)users. Fix up the kdoc on the structure. Remove the mention of FEC bypass. Seems like a niche thing to configure in the first place.

Commit 34dc2efb ("memblock: fix section mismatch warning") marked memblock_bottom_up() and memblock_set_bottom_up() as __init, but they could be referenced from non-init functions like memblock_find_in_range_node() on architectures that enable CONFIG_ARCH_KEEP_MEMBLOCK. For such builds kernel test robot reports: WARNING: modpost: vmlinux.o(.text+0x74fea4): Section mismatch in reference from the function memblock_find_in_range_node() to the function .init.text:memblock_bottom_up() The function memblock_find_in_range_node() references the function __init memblock_bottom_up(). This is often because memblock_find_in_range_node lacks a __init annotation or the annotation of memblock_bottom_up is wrong. Replace __init annotations with __init_memblock annotations so that the appropriate section will be selected depending on CONFIG_ARCH_KEEP_MEMBLOCK.

Because memblock allocations are registered with kmemleak, the KFENCE pool was seen by kmemleak as one large object. Later allocations through kfence_alloc() that were registered with kmemleak via slab_post_alloc_hook() would then overlap and trigger a warning. Therefore, once the pool is initialized, we can remove (free) it from kmemleak again, since it should be treated as allocator-internal and be seen as "free memory". The second problem is that kmemleak is passed the rounded size, and not the originally requested size, which is also the size of KFENCE objects. To avoid kmemleak scanning past the end of an object and trigger a KFENCE out-of-bounds error, fix the size if it is a KFENCE object. For simplicity, to avoid a call to kfence_ksize() in slab_post_alloc_hook() (and avoid new IS_ENABLED(CONFIG_DEBUG_KMEMLEAK) guard), just call kfence_ksize() in mm/kmemleak.c:create_object().

LLVM changed the expected function signatures for llvm_gcda_start_file() and llvm_gcda_emit_function() in the clang-11 release. Users of clang-11 or newer may have noticed their kernels failing to boot due to a panic when enabling CONFIG_GCOV_KERNEL=y +CONFIG_GCOV_PROFILE_ALL=y. Fix up the function signatures so calling these functions doesn't panic the kernel.
