2021-05-31tick/nohz: Only check for RCU deferred wakeup on user/guest entry when neededFrederic Weisbecker2-1/+9
Checking for and processing RCU-nocb deferred wakeup upon user/guest entry is only relevant when nohz_full runs on the local CPU, otherwise the periodic tick should take care of it. Make sure we don't needlessly pollute these fast-paths as a -3% performance regression on a will-it-scale.per_process_ops has been reported so far.

2021-05-26PCI/MSI: Fix MSIs for generic hosts that use device-tree's "msi-map"Jean-Philippe Brucker1-0/+2
Since commit 9ec37efb8783 ("PCI/MSI: Make pci_host_common_probe() declare its reliance on MSI domains"), platforms that rely on the "msi-map" device-tree property don't get MSIs anymore. On the Arm Fast Model for example [1], the host bridge doesn't have a "msi-parent" property since it doesn't itself generate MSIs, and so doesn't get a MSI domain. It has an "msi-map" property instead to describe MSI controllers of child devices. As a result, due to the new msi_domain check in pci_register_host_bridge(), the whole bus gets PCI_BUS_FLAGS_NO_MSI. Check whether the root complex has an "msi-map" property before giving up on MSIs.

2021-05-26net: zero-initialize tc skb extension on allocationVlad Buslov1-0/+11
Function skb_ext_add() doesn't initialize created skb extension with any value and leaves it up to the user. However, since extension of type TC_SKB_EXT originally contained only single value tc_skb_ext->chain its users used to just assign the chain value without setting whole extension memory to zero first. This assumption changed when TC_SKB_EXT extension was extended with additional fields but not all users were updated to initialize the new fields which leads to use of uninitialized memory afterwards.

Calling this function in a plane's .atomic_update ensures that all the data in the backing memory have been written to RAM. v3: - Only sync data if using GEM objects backed by non-coherent memory. - Use a drm_device pointer instead of device pointer in prototype v5: - Rename to drm_fb_cma_sync_non_coherent - Invert loops for better cache locality - Only sync BOs that have the non-coherent flag - Move to drm_fb_cma_helper.c to avoid circular dependency Signed-off-by: Paul Cercueil <paul@crapouillou.net> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20210523170415.90410-3-paul@crapouillou.net
2021-05-25drm: Add support for GEM buffers backed by non-coherent memoryPaul Cercueil1-0/+3
Having GEM buffers backed by non-coherent memory is interesting in the particular case where it is faster to render to a non-coherent buffer then sync the data cache, than to render to a write-combine buffer, and (by extension) much faster than using a shadow buffer. This is true for instance on some Ingenic SoCs, where even simple blits (e.g. memcpy) are about three times faster using this method. Add a 'map_noncoherent' flag to the drm_gem_cma_object structure, which can be set by the drivers when they create the dumb buffer. Since this really only applies to software rendering, disable this flag as soon as the CMA objects are exported via PRIME. v3: New patch. Now uses a simple 'map_noncoherent' flag to control how the objects are mapped, and use the new dma_mmap_pages function. v4: Make sure map_noncoherent is always disabled when creating GEM objects meant to be used with dma-buf.

GENMASK() has an input check which uses __builtin_choose_expr() to enable a compile time sanity check of its inputs if they are known at compile time. However, it turns out that __builtin_constant_p() does not always return a compile time constant [0]. It was thought this problem was fixed with gcc 4.9 [1], but apparently this is not the case [2]. Switch to use __is_constexpr() instead which always returns a compile time constant, regardless of its inputs.

They typically get evicted by DMABuf move notifiers of MMU notifiers. If those notifiers don't need to wait for hardware fences (i.e. the SG BOs are used in a preemptible context), then we don't need to limit them to the GTT size and we don't need TTM to evict them.

2021-05-21drivers: base: Fix device link removalRafael J. Wysocki1-4/+2
When device_link_free() drops references to the supplier and consumer devices of the device link going away and the reference being dropped turns out to be the last one for any of those device objects, its ->release callback will be invoked and it may sleep which goes against the SRCU callback execution requirements. To address this issue, make the device link removal code carry out the device_link_free() actions preceded by SRCU synchronization from a separate work item (the "long" workqueue is used for that, because it does not matter when the device link memory is released and it may take time to get to that point) instead of using SRCU callbacks. While at it, make the code work analogously when SRCU is not enabled to reduce the differences between the SRCU and non-SRCU cases.

The alpha and sparc siginfo structure layout had changed with the addition of SIGTRAP TRAP_PERF and the new field si_perf. The reason only alpha and sparc were affected is that they are the only architectures that use si_trapno. Looking deeper it was discovered that si_trapno is used for only a few select signals on alpha and sparc, and that none of the other _sigfault fields past si_addr are used at all. Which means technically no regression on alpha and sparc. While the alignment concerns might be dismissed the abuse of si_errno by SIGTRAP TRAP_PERF does have the potential to cause regressions in existing userspace. While we still have time before userspace starts using and depending on the new definition siginfo for SIGTRAP TRAP_PERF this set of changes cleans up siginfo_t. - The si_trapno field is demoted from magic alpha and sparc status and made an ordinary union member of the _sigfault member of siginfo_t.

2021-05-20block: prevent block device lookups at the beginning of del_gendiskChristoph Hellwig1-2/+0
As an artifact of how gendisk lookup used to work in earlier kernels, GENHD_FL_UP is only cleared very late in del_gendisk, and a global lock is used to prevent opens from succeeding while del_gendisk is tearing down the gendisk. Switch to clearing the flag early and under bd_mutex so that callers can use bd_mutex to stabilize the flag, which removes the need for the global mutex.
