The later revision of v3 hw has added an function of interrupt coalesce
according to time for PHY RX errors. We set the coalesce time to 1s. Then
we print PHY RX errors count when PHY RX errors happen, and don't need to
worry that there may be too much log prints.
Besides, we use hisi_sas_phy.lock to protect error count value. Because we
update them by calling phy_get_events_v3_hw(), which is also used by core
driver (for get PHY events function).
We relocate phy_get_events_v3_hw() to avoid a further declaration.

For internal IO and SMP IO, there is a time-out timer for them. In the
timer handler, it checks whether IO is done according to the flag
task->task_state_lock.
There is an issue which may cause system suspended: internal IO or SMP IO
is sent, but at that time because of hardware exception (such as inject
2Bit ECC error), so IO is not completed and also not timeout. But, at that
time, the SAS controller reset occurs to recover system. It will release
the resource and set the status of IO to be SAS_TASK_STATE_DONE, so when IO
timeout, it will never complete the completion of IO and wait for ever.

In "XFS over network block device" scenario XFS can create IO requests with
slab-based XFS metadata. During processing such requests tcp_sendpage() can
merge skb fragments with neighbour slab objects.
If receiving side is located on the same host tcp_recvmsg() can trigger
BUG_ON in hardening check and crash the host with following message:
usercopy: kernel memory exposure attempt detected
from XXXXXXXX (kmalloc-512) (1024 bytes)

Depending on the target architecture and configuration, both phys_addr_t

~~~^
There are special %pad and %pap format strings in Linux that we could use
here, but since the driver already does 64-bit arithmetic on the values,
using a plain 'u64' seems more consistent here.
Note: A possible related issue may be that the driver possibly checks the
wrong kind of overflow: when an IOMMU is in use, buffers that cross a
32-bit boundary in physical addresses would still be mapped into dma
addresses within the low 4GB space, so I suspect that we actually want to
check sg_dma_address() instead of sg_phys() here.

megaraid_sas takes 1+ seconds to load while waiting for firmware:
[2.822603] megaraid_sas 0000:03:00.0: Waiting for FW to come to ready state
[3.871003] megaraid_sas 0000:03:00.0: FW now in Ready state
This is due to the following loop in megasas_transition_to_ready(), which
waits a minimum of 1 second, even though the FW becomes ready in tens of
millisecs:
/*
* The cur_state should not last for more than max_wait secs
*/
for (i = 0; i < max_wait; i++) {
...
msleep(1000);
...
dev_info(&instance->pdev->dev, "FW now in Ready state\n");
This is a regression, caused by a change of the msleep granularity from 1
to 1000 due to concern about waiting too long on systems with coarse
jiffies.
To fix, increase iterations and use msleep(20), which results in:
[2.670627] megaraid_sas 0000:03:00.0: Waiting for FW to come to ready state

The largest thing by far is the new habanalabs driver for their AI

probably move to a new directory soon along with other drivers of this
type.
Other than that, just the usual set of individual driver updates and
fixes. There's an "odd" merge in here from the DRM tree that they
asked me to do as the MEI driver is starting to interact with the i915
driver, and it needed some coordination. All of those patches have
been properly acked by the relevant subsystem maintainers.
All of these have been in linux-next with no reported issues, most for

The virtio scsi spec defines struct virtio_scsi_ctrl_tmf as a set of
device-readable records and a single device-writable response entry:
struct virtio_scsi_ctrl_tmf
{
// Device-readable part
le32 type;
le32 subtype;
u8 lun[8];
le64 id;
// Device-writable part
u8 response;
}
The above should be organised as two descriptor entries (or potentially
more if using VIRTIO_F_ANY_LAYOUT), but without any extra data after "le64
id" or after "u8 response".
The Linux driver doesn't respect that, with virtscsi_abort() and
virtscsi_device_reset() setting cmd->sc before calling virtscsi_tmf(). It
results in the original scsi command payload (or writable buffers) added to
the tmf.
This fixes the problem by leaving cmd->sc zeroed out, which makes
virtscsi_kick_cmd() add the tmf to the control vq without any payload.

[ 5526.588562] scsi_alloc_sdev: Allocation failure during SCSI scanning, some SCSI devices might not be configured
Looking at the code of scsi_alloc_sdev(), and all the calling contexts,
there seems to be no reason to use GFP_ATMOIC here. All the different
call-contexts use a mutex at some point, and nothing in between that
requires no sleeping, as far as I could see. Additionally, the code that
later allocates the block queue for the device (scsi_mq_alloc_queue())
already uses GFP_KERNEL.
There are similar allocations in two other functions:
scsi_probe_and_add_lun(), and scsi_add_lun(),; that can also be done with
GFP_KERNEL.
Here is the contexts for the three functions so far:
scsi_alloc_sdev()
scsi_probe_and_add_lun()
scsi_sequential_lun_scan()
__scsi_scan_target()
scsi_scan_target()
mutex_lock()
scsi_scan_channel()
scsi_scan_host_selected()
mutex_lock()
scsi_report_lun_scan()
__scsi_scan_target()
...
__scsi_add_device()
mutex_lock()
__scsi_scan_target()
...
scsi_report_lun_scan()
...
scsi_get_host_dev()
mutex_lock()
scsi_probe_and_add_lun()
...
scsi_add_lun()
scsi_probe_and_add_lun()
...
So replace all these, and give them a bit of a better chance to succeed,
with more chances of reclaim.

Negative constant left-shift is undefined behaviour in the C standard, and
as such newer versions of clang (at least) warn against it. GCC supports it
for a long time, but it would be better to remove it and rely on defined
behaviour.
My understanding is "~(-1 << N)" in 2's complement is intended to generate
a bit pattern of zeroes ending with N '1' bits. The same can be achieved by
"(1 << N) - 1" in a well-defined way, so switch to it to remove the
warning.
Tested: building a kernel with generic SCSI tape, and checking basic
operations (mt status, mt eject) on a real LTO unit. Cannot test the osst
driver.

Add this functionality, placing the descriptor being read in the actual
data buffer in the bio.
That is, for both read and write descriptors query upiu, we are using the
job's request_payload. This in turn, is mapped back in user land to the
applicable sg_io_v4 xferp: dout_xferp for write descriptor, and din_xferp
for read descriptor.

When we had a write descriptor query upiu, we appended the descriptor right
after the bsg request. This was fine as the bsg driver allows to allocate
whatever buffer we needed in its job request.
Still, the proper way to deliver payload, however small (we only write
config descriptors of 144 bytes), is by using the job request payload data
buffer.
So change this ABI now, while ufs-bsg is still new, and nobody is actually
using it.

Resolution: keep HEAD, and delete the ufshcd_set_vccq_rail_unused() call
and corresponding error-handling code.
Clean up loose ends in a follow-up patch.
60f0187031c0 introduced a small power optimization: ignore the vccq load
specified in the UFSHC DT node when said host controller is connected to
specific Flash chips (currently, Samsung and Hynix).
Unfortunately, this optimization breaks UFS on systems where vccq powers
not only the Flash chip, but the host controller as well, such as APQ8098
MEDIABOX or MTP8998:

In my opinion, the rationale for the original patch is questionable. If
neither the UFSHC, nor the Flash chip, require any load from vccq, then
that power rail should simply not be specified at all in the DT.
Working around that fact in the driver is detrimental, as evidenced by the
failure to initialize the host controller on MSM8998.

It was reported that some devices report an OPTIMAL TRANSFER LENGTH of
0xFFFF blocks. That looks bogus, especially for a device with a
4096-byte physical block size.
Ignore OPTIMAL TRANSFER LENGTH if it is not a multiple of the device's
reported physical block size.
To make the sanity checking conditionals more readable--and to
facilitate printing warnings--relocate the checking to a helper
function. No functional change aside from the printks.

commit 1917d42d14b7 ("fcoe: use enum for fip_mode") introduces a separate
enum for the fip_mode that shall be used during initialisation handling
until it is passed to fcoe_ctrl_link_up to set the initial fip_state. That
change was incomplete and gcc quietly converted in various places between
the fip_mode and the fip_state enum values with implicit enum conversions,
which fortunately cannot cause any issues in the actual code's execution.
clang however warns about these implicit enum conversions in the scsi
drivers. This commit consolidates the use of the two enums, guided by
clang's enum-conversion warnings.
This commit now completes the use of the fip_mode: It expects and uses
fip_mode in {bnx2fc,fcoe}_interface_create and fcoe_ctlr_init, and it calls
fcoe_ctrl_set_set() with the correct values in fcoe_ctlr_link_up(). It
also breaks the association between FIP_MODE_AUTO and FIP_ST_AUTO to
indicate these two enums are distinct.
