2018-08-28drm/amdgpu: Need to set moved to true when evict boEmily Deng1-0/+1
Fix the VMC page fault when the running sequence is as below: 1.amdgpu_gem_create_ioctl 2.ttm_bo_swapout->amdgpu_vm_bo_invalidate, as not called amdgpu_vm_bo_base_init, so won't called list_add_tail(&base->bo_list, &bo->va). Even the bo was evicted, it won't set the bo_base->moved. 3.drm_gem_open_ioctl->amdgpu_vm_bo_base_init, here only called list_move_tail(&base->vm_status, &vm->evicted), but not set the bo_base->moved. 4.amdgpu_vm_bo_map->amdgpu_vm_bo_insert_map, as the bo_base->moved is not set true, the function amdgpu_vm_bo_insert_map will call list_move(&bo_va->base.vm_status, &vm->moved) 5.amdgpu_cs_ioctl won't validate the swapout bo, as it is only in the moved list, not in the evict list. So VMC page fault occurs. Signed-off-by: Emily Deng <[email protected]> Reviewed-by: Christian König <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

Make wmm_rule be part of the reg_rule structure. This simplifies the code a lot at the cost of having bigger memory usage. However in most cases we have only few reg_rule's and when we do have many like in iwlwifi we do not save memory as it allocates a separate wmm_rule for each channel anyway.

2018-08-28nvme-fcloop: Fix dropped LS's to removed target portJames Smart1-1/+2
When a targetport is removed from the config, fcloop will avoid calling the LS done() routine thinking the targetport is gone. This leaves the initiator reset/reconnect hanging as it waits for a status on the Create_Association LS for the reconnect. Change the filter in the LS callback path. If tport null (set when failed validation before "sending to remote port"), be sure to call done. This was the main bug. But, continue the logic that only calls done if tport was set but there is no remoteport (e.g. case where remoteport has been removed, thus host doesn't expect a completion).

2018-08-28nvme-pci: add a memory barrier to nvme_dbbuf_update_and_check_eventMichal Wnukowski1-0/+8
In many architectures loads may be reordered with older stores to different locations. In the nvme driver the following two operations could be reordered: - Write shadow doorbell (dbbuf_db) into memory. - Read EventIdx (dbbuf_ei) from memory. This can result in a potential race condition between driver and VM host processing requests (if given virtual NVMe controller has a support for shadow doorbell). If that occurs, then the NVMe controller may decide to wait for MMIO doorbell from guest operating system, and guest driver may decide not to issue MMIO doorbell on any of subsequent commands. This issue is purely timing-dependent one, so there is no easy way to reproduce it. Currently the easiest known approach is to run "Oracle IO Numbers" (orion) that is shipped with Oracle DB: orion -run advanced -num_large 0 -size_small 8 -type rand -simulate \ concat -write 40 -duration 120 -matrix row -testname nvme_test Where nvme_test is a .lun file that contains a list of NVMe block devices to run test against. Limiting number of vCPUs assigned to given VM instance seems to increase chances for this bug to occur. On test environment with VM that got 4 NVMe drives and 1 vCPU assigned the virtual NVMe controller hang could be observed within 10-20 minutes. That correspond to about 400-500k IO operations processed (or about 100GB of IO read/writes). Orion tool was used as a validation and set to run in a loop for 36 hours (equivalent of pushing 550M IO operations). No issues were observed. That suggest that the patch fixes the issue.

2018-08-27mtd: rawnand: denali: do not pass zero maxchips to nand_scan()Masahiro Yamada1-0/+5
Commit 49aa76b16676 ("mtd: rawnand: do not execute nand_scan_ident() if maxchips is zero") gave a new meaning for calling nand_scan_ident() with maxchips=0. It is a special usage for some drivers such as docg4, but actually the Denali driver may pass maxchips=0 to nand_scan() when the driver is enabled but no NAND chip is found on the board for some reasons. If nand_scan_with_ids() is called with maxchips=0, nand_scan_ident() is skipped, then nand_set_defaults() is skipped as well. Thus, the driver must set chip->controller beforehand. Otherwise, nand_attach() causes NULL pointer dereference. In fact, the Denali controller knows the number of connected chips before calling nand_scan_ident(); if DEVICE_RESET fails, there is no chip in that chip select. Then, denali_reset_banks() sets the maxchips to the number of detected chips. If no chip is found, maxchips is zero. In this case, there is no point for calling nand_scan() because we know it will fail for sure. Let's make the probe function fail immediately.

single module" The TODO item named "make spi and sdio components coexist in one build" was apparently addressed a long time ago, but never removed from the TODO file. However, the new patch that tries to address it actually makes it worse again by duplicating the common parts of the driver into two separate modules rather than sharing them. This also introduces a build regression when one of the two is built-in while the other is a loadable module: drivers/staging/wilc1000/wilc_debugfs.o:(.data+0x10): undefined reference to `__this_module' Reverting the patch makes it build again. I'm leaving the TODO file modification though, as there is nothing left to do for this item. A related problem however still seems to exist: one still cannot have multiple concurrent instances of wilc1000 devices present in the system, as there are lots of shared global variables such as host_interface.c:static struct wilc_vif *periodic_rssi_vif; wilc_sdio.c:static struct wilc_sdio g_sdio; wilc_wlan.c:static enum chip_ps_states chip_ps_state = CHIP_WAKEDUP; wilc_wlan.c:static u32 pending_acks; wilc_wfi_cfgoperations.c:int wilc_connecting; In order to have multiple instances working (sdio, spi, or mixed), all such variables need to be dynamically allocated per instance and stored in 'struct wilc' or one of the structures referenced by it.

2018-08-27xen/blkback: move persistent grants flags to boolJuergen Gross2-13/+7
The struct persistent_gnt flags member is meant to be a bitfield of different flags. There is only PERSISTENT_GNT_ACTIVE flag left, so convert it to a bool named "active".

2018-08-27xen/blkfront: reorder tests in xlblk_init()Juergen Gross1-9/+9
In case we don't want pv block devices we should not test parameters for sanity and eventually print out error messages. So test precluding conditions before checking parameters.

2018-08-27xen/blkfront: cleanup stale persistent grantsJuergen Gross1-4/+90
Add a periodic cleanup function to remove old persistent grants which are no longer in use on the backend side. This avoids starvation in case there are lots of persistent grants for a device which no longer is involved in I/O business.

2018-08-27xen/blkback: don't keep persistent grants too longJuergen Gross2-46/+50
Persistent grants are allocated until a threshold per ring is being reached. Those grants won't be freed until the ring is being destroyed meaning there will be resources kept busy which might no longer be used. Instead of freeing only persistent grants until the threshold is reached add a timestamp and remove all persistent grants not having been in use for a minute.

2018-08-27USB: serial: ti_usb_3410_5052: fix array underflow in completion handlerJohan Hovold1-1/+1
Similarly to a recently reported bug in io_ti, a malicious USB device could set port_number to a negative value and we would underflow the port array in the interrupt completion handler. As these devices only have one or two ports, fix this by making sure we only consider the seventh bit when determining the port number (and ignore bits 0xb0 which are typically set to 0x30).

2018-08-27mtd: rawnand: docg4: Remove wrong __init annotationsGeert Uytterhoeven1-2/+2
If gcc (e.g. 4.1.2) decides not to inline init_mtd_structs() and read_id_reg(), this will cause section mismatches, and crashes: WARNING: drivers/mtd/nand/raw/docg4.o(.text+0xc10): Section mismatch in reference from the function docg4_attach_chip() to the function .init.text:init_mtd_structs() The function docg4_attach_chip() references the function __init init_mtd_structs(). This is often because docg4_attach_chip lacks a __init annotation or the annotation of init_mtd_structs is wrong. WARNING: drivers/mtd/nand/raw/docg4.o(.text+0xc3e): Section mismatch in reference from the function docg4_attach_chip() to the function .init.text:read_id_reg() The function docg4_attach_chip() references the function __init read_id_reg(). This is often because docg4_attach_chip lacks a __init annotation or the annotation of read_id_reg is wrong. Fix this by dropping the now incorrect __init annotations from init_mtd_structs() and read_id_reg().

2018-08-27drm/mediatek: use layer_nr function to get layer number to init planeStu Hsieh2-8/+14
This patch use layer_nr function to get layer number to init plane When plane init in crtc create, it use the number of OVL layer to init plane. That's OVL can read 4 memory address. For mt2712 third ddp, it use RDMA to read memory. RDMA can read 1 memory address, so it just init one plane. For compatibility, this patch use mtk_ddp_comp_layer_nr function to get layer number from their HW component in ddp for plane init.
