2018-08-27drm/amd/display: Add support for toggling DFS bypassNicholas Kazlauskas4-6/+76
[Why] If the hardware supports DFS bypass it will always be enabled after creation of the DCCG. DFS bypass should only be enabled when the current stream consists of a single embedded panel and the minimum display clock is below the DFS bypass threshold. [How] Add a function to the DCCG table that updates the DFS bypass state when setting the bandwidth. If the DFS bypass state is changed, the clock needs to be reprogrammed to reflect this before the DPREFCLK is updated for audio endpoints. The existing display clock value is used as the target display clock value when reprogramming since the resulting change will be equal or larger to the current value. These changes only specifically target dce110 but do offer a framework for support on other applicable targets.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fixes from Thomas Gleixner: - Correct the L1TF fallout on 32bit and the off by one in the 'too much RAM for protection' calculation. - Add a helpful kernel message for the 'too much RAM' case - Unbreak the VDSO in case that the compiler desides to use indirect jumps/calls and emits retpolines which cannot be resolved because the kernel uses its own thunks, which does not work for the VDSO. Make it use the builtin thunks. - Re-export start_thread() which was unexported when the 32/64bit implementation was unified. start_thread() is required by modular binfmt handlers. - Trivial cleanups * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/speculation/l1tf: Suggest what to do on systems with too much RAM x86/speculation/l1tf: Fix off-by-one error when warning that system has too much RAM x86/kvm/vmx: Remove duplicate l1d flush definitions x86/speculation/l1tf: Fix overflow in l1tf_pfn_limit() on 32bit x86/process: Re-export start_thread() x86/mce: Add notifier_block forward declaration x86/vdso: Fix vDSO build if a retpoline is emitted

gitolite.kernel.org:pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm memory-failure update from Dave Jiang: "As it stands, memory_failure() gets thoroughly confused by dev_pagemap backed mappings. The recovery code has specific enabling for several possible page states and needs new enabling to handle poison in dax mappings. In order to support reliable reverse mapping of user space addresses: 1/ Add new locking in the memory_failure() rmap path to prevent races that would typically be handled by the page lock. 2/ Since dev_pagemap pages are hidden from the page allocator and the "compound page" accounting machinery, add a mechanism to determine the size of the mapping that encompasses a given poisoned pfn. 3/ Given pmem errors can be repaired, change the speculatively accessed poison protection, mce_unmap_kpfn(), to be reversible and otherwise allow ongoing access from the kernel. A side effect of this enabling is that MADV_HWPOISON becomes usable for dax mappings, however the primary motivation is to allow the system to survive userspace consumption of hardware-poison via dax. Specifically the current behavior is: mce: Uncorrected hardware memory error in user-access at af34214200 {1}[Hardware Error]: It has been corrected by h/w and requires no further action mce: [Hardware Error]: Machine check events logged {1}[Hardware Error]: event severity: corrected Memory failure: 0xaf34214: reserved kernel page still referenced by 1 users [..] Memory failure: 0xaf34214: recovery action for reserved kernel page: Failed mce: Memory error not recovered <reboot> ...and with these changes: Injecting memory failure for pfn 0x20cb00 at process virtual address 0x7f763dd00000 Memory failure: 0x20cb00: Killing dax-pmd:5421 due to hardware memory corruption Memory failure: 0x20cb00: recovery action for dax page: Recovered Given all the cross dependencies I propose taking this through nvdimm.git with acks from Naoya, x86/core, x86/RAS, and of course dax folks" * tag 'libnvdimm-for-4.19_dax-memory-failure' of gitolite.kernel.org:pub/scm/linux/kernel/git/nvdimm/nvdimm: libnvdimm, pmem: Restore page attributes when clearing errors x86/memory_failure: Introduce {set, clear}_mce_nospec() x86/mm/pat: Prepare {reserve, free}_memtype() for "decoy" addresses mm, memory_failure: Teach memory_failure() about dev_pagemap pages filesystem-dax: Introduce dax_lock_mapping_entry() mm, memory_failure: Collect mapping size in collect_procs() mm, madvise_inject_error: Let memory_failure() optionally take a page reference mm, dev_pagemap: Do not clear ->mapping on final put mm, madvise_inject_error: Disable MADV_SOFT_OFFLINE for ZONE_DEVICE pages filesystem-dax: Set page->index device-dax: Set page->index device-dax: Enable page_mapping() device-dax: Convert to vmf_insert_mixed and vm_fault_t
