2021-08-03wan: remove sbni/granch driverArnd Bergmann1-2/+0
The driver was merged in 1999 and has only ever seen treewide cleanups since then, with no indication whatsoever that anyone has actually had access to hardware for testing the patches. >From the information in the link below, it appears that the hardware is for some leased line system in Russia that has since been discontinued, and useless without any remote end to connect to. As the driver still feels like a Linux-2.2 era artifact today, it appears that the best way forward is to just delete it.

2021-08-03bonding: add new option lacp_activeHangbin Liu1-0/+12
Add an option lacp_active, which is similar with team's runner.active. This option specifies whether to send LACPDU frames periodically. If set on, the LACPDU frames are sent along with the configured lacp_rate setting. If set off, the LACPDU frames acts as "speak when spoken to". Note, the LACPDU state frames still will be sent when init or unbind port. v2: remove module parameter Signed-off-by: Hangbin Liu <liuhangbin@gmail.com> Signed-off-by: David S.

2021-08-03KVM: Block memslot updates across range_start() and range_end()Paolo Bonzini1-0/+6
We would like to avoid taking mmu_lock for .invalidate_range_{start,end}() notifications that are unrelated to KVM. Because mmu_notifier_count must be modified while holding mmu_lock for write, and must always be paired across start->end to stay balanced, lock elision must happen in both or none. Therefore, in preparation for this change, this patch prevents memslot updates across range_start() and range_end(). Note, technically flag-only memslot updates could be allowed in parallel, but stalling a memslot update for a relatively short amount of time is not a scalability issue, and this is all more than complex enough. A long note on the locking: a previous version of the patch used an rwsem to block the memslot update while the MMU notifier run, but this resulted in the following deadlock involving the pseudo-lock tagged as "mmu_notifier_invalidate_range_start". ====================================================== WARNING: possible circular locking dependency detected 5.12.0-rc3+ #6 Tainted: G OE ------------------------------------------------------ qemu-system-x86/3069 is trying to acquire lock: ffffffff9c775ca0 (mmu_notifier_invalidate_range_start){+.+.}-{0:0}, at: __mmu_notifier_invalidate_range_end+0x5/0x190 but task is already holding lock: ffffaff7410a9160 (&kvm->mmu_notifier_slots_lock){.+.+}-{3:3}, at: kvm_mmu_notifier_invalidate_range_start+0x36d/0x4f0 [kvm] which lock already depends on the new lock. This corresponds to the following MMU notifier logic: invalidate_range_start take pseudo lock down_read() (*) release pseudo lock invalidate_range_end take pseudo lock (**) up_read() release pseudo lock At point (*) we take the mmu_notifiers_slots_lock inside the pseudo lock; at point (**) we take the pseudo lock inside the mmu_notifiers_slots_lock. This could cause a deadlock (ignoring for a second that the pseudo lock is not a lock): - invalidate_range_start waits on down_read(), because the rwsem is held by install_new_memslots - install_new_memslots waits on down_write(), because the rwsem is held till (another) invalidate_range_end finishes - invalidate_range_end sits waits on the pseudo lock, held by invalidate_range_start. Removing the fairness of the rwsem breaks the cycle (in lockdep terms, it would change the *shared* rwsem readers into *shared recursive* readers), so open-code the wait using a readers count and a spinlock. This also allows handling blockable and non-blockable critical section in the same way. Losing the rwsem fairness does theoretically allow MMU notifiers to block install_new_memslots forever. Note that mm/mmu_notifier.c's own retry scheme in mmu_interval_read_begin also uses wait/wake_up and is likewise not fair. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2021-08-01scsi: ufs: ufshpb: Add HPB 2.0 supportDaejun Park1-0/+35
Version 2.0 of HBP supports reads of varying sizes from 4KB to 1MB. A read operation <= 32KB is supported as single HPB read. A read between 36KB and 1MB is supported by a combination of write buffer command and HPB read command to deliver more PPN. The write buffer commands may not be issued immediately due to busy tags. To use HPB read more aggressively, the driver can requeue the write buffer command. The requeue threshold is implemented as timeout and can be modified with requeue_timeout_ms entry in sysfs.

2021-08-01scsi: ufs: ufshpb: Introduce Host Performance Buffer featureDaejun Park1-0/+127
Implement Host Performance Buffer (HPB) initialization and add function calls to UFS core driver. NAND flash-based storage devices, including UFS, have mechanisms to translate logical addresses of I/O requests to the corresponding physical addresses of the flash storage. In UFS, logical-to-physical-address (L2P) map data, which is required to identify the physical address for the requested I/Os, can only be partially stored in SRAM from NAND flash. Due to this partial loading, accessing the flash address area, where the L2P information for that address is not loaded in the SRAM, can result in serious performance degradation. The basic concept of HPB is to cache L2P mapping entries in host system memory so that both physical block address (PBA) and logical block address (LBA) can be delivered in HPB read command. The HPB read command allows to read data faster than a regular read command in UFS since it provides the physical address (HPB Entry) of the desired logical block in addition to its logical address. The UFS device can access the physical block in NAND directly without searching and uploading L2P mapping table. This improves read performance because the NAND read operation for uploading L2P mapping table is removed. In HPB initialization, the host checks if the UFS device supports HPB feature and retrieves related device capabilities. Then, HPB parameters are configured in the device. Total start-up time of popular applications was measured and the difference observed between HPB being enabled and disabled. Popular applications are 12 game apps and 24 non-game apps. Each test cycle consists of running 36 applications in sequence. We repeated the cycle for observing performance improvement by L2P mapping cache hit in HPB. The following is the test environment: - kernel version: 4.4.0 - RAM: 8GB - UFS 2.1 (64GB) Results: +-------+----------+----------+-------+ | cycle | baseline | with HPB | diff | +-------+----------+----------+-------+ | 1 | 272.4 | 264.9 | -7.5 | | 2 | 250.4 | 248.2 | -2.2 | | 3 | 226.2 | 215.6 | -10.6 | | 4 | 230.6 | 214.8 | -15.8 | | 5 | 232.0 | 218.1 | -13.9 | | 6 | 231.9 | 212.6 | -19.3 | +-------+----------+----------+-------+ We also measured HPB performance using iozone: $ iozone -r 4k -+n -i2 -ecI -t 16 -l 16 -u 16 -s $IO_RANGE/16 -F \ mnt/tmp_1 mnt/tmp_2 mnt/tmp_3 mnt/tmp_4 mnt/tmp_5 mnt/tmp_6 mnt/tmp_7 \ mnt/tmp_8 mnt/tmp_9 mnt/tmp_10 mnt/tmp_11 mnt/tmp_12 mnt/tmp_13 \ mnt/tmp_14 mnt/tmp_15 mnt/tmp_16 Results: +----------+--------+---------+ | IO range | HPB on | HPB off | +----------+--------+---------+ | 1 GB | 294.8 | 300.87 | | 4 GB | 293.51 | 179.35 | | 8 GB | 294.85 | 162.52 | | 16 GB | 293.45 | 156.26 | | 32 GB | 277.4 | 153.25 | +----------+--------+---------+ Link: https://lore.kernel.org/r/20210712085830epcms2p8c1288b7f7a81b044158a18232617b572@epcms2p8 Reported-by: kernel test robot <lkp@intel.com> Tested-by: Bean Huo <beanhuo@micron.com> Tested-by: Can Guo <cang@codeaurora.org> Tested-by: Stanley Chu <stanley.chu@mediatek.com> Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Reviewed-by: Bart Van Assche <bvanassche@acm.org> Reviewed-by: Can Guo <cang@codeaurora.org> Reviewed-by: Bean Huo <beanhuo@micron.com> Reviewed-by: Stanley Chu <stanley.chu@mediatek.com> Acked-by: Avri Altman <Avri.Altman@wdc.com> Signed-off-by: Daejun Park <daejun7.park@samsung.com> Signed-off-by: Martin K.

2021-07-30dt-bindings: arm: Convert Gemini boards to YAMLLinus Walleij3-108/+105
This removes the old plaintext Gemini binding and replace it with a YAML schema, adding some new boards in the process. While we are at it, add the missing vendors to the vendor prefix file. Drop the overly deliberate description of subnodes and the big example from the old document. Keep the elaborate description. I noticed that "wiliboard" is not a real vendor, the vendor is named "wiligear" so deprecated this and replaced with the proper vendor.

Allow to extend expression of sub nodes to optionally indicate bit position. This extension is needed to distinguish between different bit positions in the same address. For example, there are two nvmem nodes starting with bit 4 and bit 0 at the same address 0x54. In this case, it can be expressed as follows. trim@54,4 { reg = <0x54 1>; bits = <4 2>; }; trim@54,0 { reg = <0x54 1>; bits = <0 4>; }; Signed-off-by: Kunihiko Hayashi <hayashi.kunihiko@socionext.com> Link: https://lore.kernel.org/r/1626661864-15473-2-git-send-email-hayashi.kunihiko@socionext.com Signed-off-by: Rob Herring <robh@kernel.org>

2021-07-29printk: Add printk.console_no_auto_verbose boot parameterDmitry Safonov1-0/+9
console_verbose() increases console loglevel to CONSOLE_LOGLEVEL_MOTORMOUTH, which provides more information to debug a panic/oops. Unfortunately, in Arista we maintain some DUTs (Device Under Test) that are configured to have 9600 baud rate. While verbose console messages have their value to post-analyze crashes, on such setup they: - may prevent panic/oops messages being printed - take too long to flush on console resulting in watchdog reboot In all our setups we use kdump which saves dmesg buffer after panic, so in reality those extra messages on console provide no additional value, but rather add risk of not getting to __crash_kexec(). Provide printk.console_no_auto_verbose boot parameter, which allows to switch off printk being verbose on oops/panic/lockdep.

2021-07-29drm: clarify usage of drm leasesDesmond Cheong Zhi Xi1-0/+9
We make the following changes to the documentation of drm leases to make it easier to reason about their usage. In particular, we clarify the lifetime and locking rules of lease fields in drm_master: 1. Make it clear that &drm_device.mode_config.idr_mutex protects the lease idr and list structures for drm_master. The lessor field itself doesn't need to be protected as it doesn't change after it's set in drm_lease_create. 2. Add descriptions for the lifetime of lessors and leases. 3. Add an overview DOC: section in drm-uapi.rst that defines the terminology for drm leasing, and explains how leases work and why they're used.
