[PATCH v2] mtd: spi-nor: check 4-byte address support when parsing 4bait
by Yicong Yang 02 Feb '21

02 Feb '21

The spi-nor core will convert the address mode to 4-btye, without checking whether 4-byte address is supported or not. For example, the 16M s25fs128s1 can work under both 3-byte and 4-byte address and provides a 4bait table. The spi-nor will drive the flash under 4-byte address mode after parsing the 4bait and will cause it unusable on platforms doesn't support 4-byte. Add checking of 4-byte address support when parsing the 4bait table, stop converting the address mode if it's not supported. The issue maybe addressed by moving the address mode set and 4-byte operation check out of paring 4bait table[1], but fix this with this patch to make the flash work properly on some platform first.

[PATCH 0/2] Add check of 4-byte when parsing SFDP 4bait table
by Yicong Yang 01 Feb '21

01 Feb '21

Add check of 4-byte address mode support when parsing SFDP 4bait. Some flash will provide a 4bait table and the spi-nor core will convert the address mode to 4-byte without checking whether it's actually supported or not by the controller. For example, the 16M s25fs128s1 provides the 4bait and will be convert to 4-byte address mode, which makes it unusable on hisi-sfc-v3xx on hip08 platform. Add the check before convert the address mode when parsing the 4bait will solve this issue.

[PATCH v2] iommu: Check dev->iommu in iommu_dev_xxx functions
by Shameer Kolothum 01 Feb '21

01 Feb '21

The device iommu probe/attach might have failed leaving dev->iommu to NULL and device drivers may still invoke these functions resulting in a crash in iommu vendor driver code. Hence make sure we check that. Also added iommu_ops to the "struct dev_iommu" and set it if the dev is successfully associated with an iommu.

Hi Team, I have a question about bonding. During testing bonding mode 4 scenarios, I find that there is a very low probability that the pointer is null. The following information is displayed: [99359.795934] bond0: (slave eth13.2001): Port 2 did not find a suitable aggregator [99359.796960] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000020 [99359.798127] Mem abort info: [99359.798526] ESR = 0x96000004 [99359.798938] EC = 0x25: DABT (current EL), IL = 32 bits [99359.799673] SET = 0, FnV = 0 [99359.800106] EA = 0, S1PTW = 0 [99359.800554] Data abort info: [99359.800952] ISV = 0, ISS = 0x00000004 [99359.801522] CM = 0, WnR = 0 [99359.801970] user pgtable: 4k pages, 48-bit VAs, pgdp=00000000c64e6000 [99359.802876] [0000000000000020] pgd=0000000000000000 [99359.803555] Internal error: Oops: 96000004 [#1] PREEMPT SMP [99359.804369] Modules linked in: bonding hns3(-) hclgevf hnae3 [last unloaded: bonding] [99359.805494] CPU: 1 PID: 951 Comm: kworker/u10:2 Not tainted 5.7.0-rc4+ #1 [99359.806455] Hardware name: linux,dummy-virt (DT) [99359.807107] Workqueue: bond0 bond_3ad_state_machine_handler [bonding] [99359.808056] pstate: 60c00005 (nZCv daif +PAN +UAO) [99359.808722] pc : bond_3ad_state_machine_handler+0x7fc/0xdb8 [bonding] [99359.809652] lr : bond_3ad_state_machine_handler+0x7f4/0xdb8 [bonding] [99359.810535] sp : ffff80001882bd20 [99359.811012] x29: ffff80001882bd20 x28: ffff000085939a38 [99359.811791] x27: ffff00008649bb68 x26: 00000000aaaaaaab [99359.812871] x25: ffff800009401000 x24: ffff800009408de4 [99359.814049] x23: ffff80001882bd98 x22: ffff00008649b880 [99359.815210] x21: 0000000000000000 x20: ffff000085939a00 [99359.816401] x19: ffff00008649b880 x18: ffff800012572988 [99359.817637] x17: 0000000000000000 x16: 0000000000000000 [99359.818870] x15: ffff80009882b987 x14: 726f746167657267 [99359.820090] x13: 676120656c626174 x12: 697573206120646e [99359.821374] x11: 696620746f6e2064 x10: 696420322074726f [99359.822659] x9 : 50203a2931303032 x8 : 0000000000081391 [99359.823891] x7 : ffff8000108e3ad0 x6 : ffff8000128858bb [99359.825109] x5 : 0000000000000000 x4 : 0000000000000000 [99359.826262] x3 : 00000000ffffffff x2 : 906b329bb5362a00 [99359.827394] x1 : 906b329bb5362a00 x0 : 0000000000000000 [99359.828540] Call trace: [99359.829071] bond_3ad_state_machine_handler+0x7fc/0xdb8 [bonding] [99359.830367] process_one_work+0x15c/0x4a0 [99359.831216] worker_thread+0x50/0x478 [99359.832022] kthread+0x130/0x160 [99359.832716] ret_from_fork+0x10/0x18 [99359.833487] Code: 910c0021 95f704bb f9403f80 b5ffe300 (f9401000) [99359.834742] ---[ end trace c7a8e02914afc4e0 ]--- [99359.835817] Kernel panic - not syncing: Fatal exception in interrupt [99359.837334] SMP: stopping secondary CPUs [99359.838277] Kernel Offset: disabled [99359.839086] CPU features: 0x080002,22208218 [99359.840053] Memory Limit: none [99359.840783] ---[ end Kernel panic - not syncing: Fatal exception in interrupt ]--- The test procedure is as follows: 1.

[PATCH for-next] RDMA/hns: Add support of direct wqe
by Weihang Li 30 Jan '21

From: Yixing Liu <liuyixing1(a)huawei.com> Direct wqe is a mechanism to fill wqe directly into the hardware. In the case of light load, the wqe will be filled into pcie bar space of the hardware, this will reduce one memory access operation and therefore reduce the latency.
