2021-05-03vringh: add 'iotlb_lock' to synchronize iotlb accessesStefano Garzarella2-2/+10
Usually iotlb accesses are synchronized with a spinlock. Let's request it as a new parameter in vringh_set_iotlb() and hold it when we navigate the iotlb in iotlb_translate() to avoid race conditions with any new additions/deletions of ranges from the ioltb.

2021-05-03vdpa_sim: use iova module to allocate IOVA addressesStefano Garzarella3-42/+69
The identical mapping used until now created issues when mapping different virtual pages with the same physical address. To solve this issue, we can use the iova module, to handle the IOVA allocation. For simplicity we use an IOVA allocator with byte granularity. We add two new functions, vdpasim_map_range() and vdpasim_unmap_range(), to handle the IOVA allocation and the registration into the IOMMU/IOTLB. These functions are used by dma_map_ops callbacks.

2021-05-03vhost-vdpa: fix vm_flags for virtqueue doorbell mappingJason Wang1-0/+1
The virtqueue doorbell is usually implemented via registeres but we don't provide the necessary vma->flags like VM_PFNMAP. This may cause several issues e.g when userspace tries to map the doorbell via vhost IOTLB, kernel may panic due to the page is not backed by page structure. This patch fixes this by setting the necessary vm_flags. With this patch, try to map doorbell via IOTLB will fail with bad address.

2021-05-03drm/msm/dpu: Delete bonkers codeRob Clark3-32/+0
dpu_crtc_atomic_flush() was directly poking it's attached planes in a code path that ended up in dpu_plane_atomic_update(), even if the plane was not involved in the current atomic update. While a bit dubious, this worked before because plane->state would always point to something valid. But now using drm_atomic_get_new_plane_state() we could get a NULL state pointer instead, leading to: [ 20.873273] Call trace: [ 20.875740] dpu_plane_atomic_update+0x5c/0xed0 [ 20.880311] dpu_plane_restore+0x40/0x88 [ 20.884266] dpu_crtc_atomic_flush+0xf4/0x208 [ 20.888660] drm_atomic_helper_commit_planes+0x150/0x238 [ 20.894014] msm_atomic_commit_tail+0x1d4/0x7a0 [ 20.898579] commit_tail+0xa4/0x168 [ 20.902102] drm_atomic_helper_commit+0x164/0x178 [ 20.906841] drm_atomic_commit+0x54/0x60 [ 20.910798] drm_atomic_connector_commit_dpms+0x10c/0x118 [ 20.916236] drm_mode_obj_set_property_ioctl+0x1e4/0x440 [ 20.921588] drm_connector_property_set_ioctl+0x60/0x88 [ 20.926852] drm_ioctl_kernel+0xd0/0x120 [ 20.930807] drm_ioctl+0x21c/0x478 [ 20.934235] __arm64_sys_ioctl+0xa8/0xe0 [ 20.938193] invoke_syscall+0x64/0x130 [ 20.941977] el0_svc_common.constprop.3+0x5c/0xe0 [ 20.946716] do_el0_svc+0x80/0xa0 [ 20.950058] el0_svc+0x20/0x30 [ 20.953145] el0_sync_handler+0x88/0xb0 [ 20.957014] el0_sync+0x13c/0x140 The reason for the codepath seems dubious, the atomic suspend/resume heplers should handle the power-collapse case.

Make sure that the cmd_per_lun value placed in the host template never exceeds the can_queue value. If the max_queue driver parameter is not specified then both cmd_per_lun and can_queue are set to CAN_QUEUE. CAN_QUEUE is a compile time constant and is used to dimension an array to hold queued requests. If the max_queue driver parameter is given it is must be less than or equal to CAN_QUEUE and if so, the host template values are adjusted. Remove undocumented code that allowed queue_depth to exceed CAN_QUEUE and cause stack full type errors. There is a documented way to do that with every_nth and echo 0x8000 > /sys/bus/pseudo/drivers/scsi_debug/opts See: https://sg.danny.cz/sg/scsi_debug.html Tweak some formatting, and add a suggestion to the "trim poll_queues" warning.

Currently, netif_tx_stop_all_queues() is used to ensure that the xmit is not running, but for the concurrent case it will not take effect, since netif_tx_stop_all_queues() just sets a flag without locking to indicate that the xmit queue(s) should not be run. So use netif_tx_disable() to replace netif_tx_stop_all_queues(), it takes the xmit queue lock while marking the queue stopped.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "There is a lot going on! Core changes: - A semantic change to handle pinmux and pinconf in explicit order while up until now we depended on the semantic order in the device tree. The device tree is a functional programming language and does not imply any order, so the right thing is for the pin control core to provide these semantics. - Add a new pinmux-select debugfs file which makes it possible to go in and select functions for a pin manually (iteratively, at the prompt) for debugging purposes. - Fixes to gpio regmap handling for a new pin control driver making use of regmap-gpio. - Use octal permissions on debugfs files. New drivers: - A massive rewrite of the former custom pin control driver for MIPS Broadcom devices to instead use the pin control subsystem. New pin control drivers for BCM6345, BCM6328, BCM6358, BCM6362, BCM6368, BCM63268 and BCM6318 SoC variants are implemented. - Support for PM8350, PM8350B, PM8350C, PMK8350, PMR735A and PMR735B in the Qualcomm PMIC GPIO driver. Also the two GPIOs on PM8008 are supported. - Support for the Rockchip RK3568/RK3566 pin controller. - Support for Ingenic JZ4730, JZ4750, JZ4755, JZ4775 and X2000. - Support for Mediatek MTK8195. - Add a new Xilinx ZynqMP pin control driver. Driver improvements and non-urgent fixes: - Modularization and improvements of the Rockchip drivers. - Some new pins added to the description of new Renesas SoCs. - Clarifications of the GPIO base calculation in the Intel driver. - Fix the function names for the MPP54 and MPP55 pins in the Armada CP110 pin controller. - GPIO wakeup interrupt map for Qualcomm SC7280 and SM8350. - Support for ACPI probing of the Qualcomm SC8180x. - Fix interrupt clear status on rockchip - Fix some missing pins on the Ingenic JZ4770, some semantic fixes for the behaviour of the Ingenic pin controller.

2021-04-30PCI: Allow VPD access for QLogic ISP2722Arun Easi1-1/+0
0d5370d1d852 ("PCI: Prevent VPD access for QLogic ISP2722") disabled access to VPD of the ISP2722-based 16/32Gb Fibre Channel to PCIe Adapter because reading past the end of the VPD caused NMIs. 104daa71b396 ("PCI: Determine actual VPD size on first access") limits reads to the actual size of VPD, which should prevent these NMIs. 104daa71b396 was merged *before* 0d5370d1d852, but we think the testing that prompted 0d5370d1d852 ("PCI: Prevent VPD access for QLogic ISP2722") was done with a kernel that lacked 104daa71b396. See [1, 2]. Remove the quirk added by 0d5370d1d852 ("PCI: Prevent VPD access for QLogic ISP2722") so customers can read the HBA VPD.
