Subject: [PATCH 01/31] scsi: hisi_sas: Feed back linkrate(max/min) when
re-attached
Origin: https://git.kernel.org/linus/5a54691f874ab29ec82f08bc6936866a3ccdaa91
At directly attached situation, if the user modifies the sysfs interface
of maximum_linkrate and minimum_linkrate to renegotiate the linkrate
between SAS controller and target, the value of both files mentioned
above should have change to user setting after renegotiate is over, but
it remains unchanged.
To fix this bug, maximum_linkrate and minimum_linkrate will be directly
fed back to relevant sas_phy structure.

Subject: [PATCH 03/31] scsi: hisi_sas: Fix the race between IO completion and
timeout for SMP/internal IO
Origin: https://git.kernel.org/linus/584f53fe5f529d877968c711a095923c1ed12307
If SMP/internal IO times out, we will possibly free the task immediately.
However if the IO actually completes at the same time, the IO completion
may refer to task which has been freed.
So to solve the issue, flush the tasklet to finish IO completion before
free'ing slot/task.

Origin: https://git.kernel.org/linus/3e178f3ecfcf91a258e832b0f0843a4cfd9059ac
If an SSP/SMP IO times out, it may be actually in reality be
simultaneously processing completion of the slot in
slot_complete_vx_hw().
Then if the slot is freed in slot_complete_vx_hw() (this IPTT is freed
and it may be re-used by other slot), and we may abort the wrong slot in
hisi_sas_abort_task().
So to solve the issue, free the slot after the check of
SAS_TASK_STATE_ABORTED in slot_complete_vx_hw().

so we need to unmask the interrupts and process them first in the driver.

Origin: https://git.kernel.org/linus/784b46b7cba0ae914dd293f23848c5057c6ba017
Currently we use the IPTT defined in LLDD to identify IOs. Actually for
IOs which are from the block layer, they have tags to identify them. So
for those IOs, use tag of the block layer directly, and for IOs which is
not from the block layer (such as internal IOs from libsas/LLDD), reserve
96 IPTTs for them.

Subject: [PATCH 07/31] scsi: hisi_sas: Update v3 hw AIP_LIMIT and
CFG_AGING_TIME register values
Origin: https://git.kernel.org/linus/3bccfba8312762becfb05b35d698ba8cffd440f2
Update registers as follows:
- Default value of AIP timer is 1ms, and it is easy for some expanders to
cause IO error. Change the value to max value 65ms to avoid IO error for
those expanders.
- A CQ completion will be reported by HW when 4 CQs have occurred or the
aging timer expires, whichever happens first. Sor serial IO scenario, it
will still wait 8us for every IO before it is reported. So in the
situation, the performance is poor. So to improve it, change the limit
time to the least value.
For other scenario, it does little affect to the performance.

Subject: [PATCH 11/31] scsi: hisi_sas: Add support for interrupt converge for
v3 hw
Origin: https://git.kernel.org/linus/488cf558e3d7c95daf737d9cae165019ee3f2840
If CQ_INT_CONVERGE_EN is enabled, the interrupts of all the 16 CQ queues
will be reported by CQ0.
So we need to change the process of CQ tasklet for this situation.

Subject: [PATCH 12/31] scsi: hisi_sas: Add support for interrupt coalescing
for v3 hw
Origin: https://git.kernel.org/linus/37359798ec44ae03fab383a9bef3b7c9df819063
If INT_COAL_EN is enabled, configure time and count of interrupt
coalescing. Then if CQ collects count of CQ entries in time, it will
report the interrupt. Or if CQ doesn't collect enough CQ entries in time,
it will report the interrupt at timeout.
As all the registers are not supported to be changed dynamically, we need
to config those register between disable and enable PHYs.

Subject: [PATCH 13/31] scsi: hisi_sas: Relocate some codes to avoid an unused
check
Origin: https://git.kernel.org/linus/745b6847634c11dda1079d0290781a443eddb4b7
In function hisi_sas_task_prep(), we check asd_sas_port, but in function
hisi_sas_task_exec(), we already refer to asd_sas_port by using function
dev_to_hisi_hba() implicitly. So to avoid this possible invalid
dereference, relocate the check to function hisi_sas_task_prep().

Subject: [PATCH 15/31] scsi: hisi_sas: Relocate some code to reduce complexity
Origin: https://git.kernel.org/linus/6e1b731b535231e199c7810451c851398afccd33
Relocate the codes related to dma_map/unmap in hisi_sas_task_prep() to
reduce complexity, with a view to add DIF/DIX support.

Subject: [PATCH 16/31] scsi: hisi_sas: Make sg_tablesize consistent value
Origin: https://git.kernel.org/linus/6db831f4ef764ca19d7300d56ab9455af3cb930d
Sht->sg_tablesize is set in the driver, and it will be assigned to
shost->sg_tablesize in SCSI mid-layer. So it is not necessary to assign
shost->sg_table one more time in the driver.
In addition to the change, change each scsi_host_template.sg_tablesize
to HISI_SAS_SGE_PAGE_CNT instead of SG_ALL.

When doing reset, it is unnecessary to get the hardware's default
configuration again, otherwise, the user's configuration will be
overwritten.

This patch adds support of getting tx and dv buffer size through

size of tx and dv buffer.
This patch also add dv_buf_size to tc' private buffer size even if
pfc is not enable for the tc.

Origin: https://git.kernel.org/linus/b9a400ac295728b2d47445e09814e1880409b311
The hardware expects the buffer size set to SSU is aligned to
256 bytes, this patch aligns the buffer size to 256 byte using
roundup or rounddown function.

Subject: [PATCH 22/31] net: hns3: fix a SSU buffer checking bug
Origin: https://git.kernel.org/linus/af854724e51e4047f534ac6d19b3ef9fb3c35c49
When caculating the SSU buffer, it first allocate tx and
rx private buffer, then the remaining buffer is for rx
shared buffer. The remaining buffer size should be at
least bigger than or equal to the shared_std, which is the
minimum shared buffer size required by the driver, but
currently if the remaining buffer size is equal to the
shared_std, it returns failure, which causes SSU buffer
allocation failure problem.
This patch fixes this problem by rounding up shared_std before
checking the the remaining buffer size bigger than or equal to
the shared_std.

Origin: https://git.kernel.org/linus/a298797532d9dc244abf349d7c2ed063732c6ba3
In original codes, default tc value is set to the max tc. It's more
reasonable to close tc by changing default tc value to 1. Users can
enable it with lldp tool when they want to use tc.

Origin: https://git.kernel.org/linus/e888402789b9db5de4fcda361331d66dbf0cd9fd
For HNAE3_DOWN_CLIENT calling hns3_nic_net_stop(), HNAE3_UP_CLIENT
should call hns3_nic_net_open(), since if the number of queue or
the map of TC has is changed before HHAE3_UP_CLIENT is called,
it will cause problem.
Also the HNS3_NIC_STATE_RESETTING flag needs to be cleared before
hns3_nic_net_open() called, and set it back while hns3_nic_net_open()
failed.

timeout
Origin: https://git.kernel.org/linus/44754b95dd35ee07c462b5425ae9c4cde8c7e7c8
According to IB protocol, local ACK timeout shall be a 5 bit
value. Currently, hip08 could not support the possible max value 31. Fail
the request in this case.

When flush cqe, it needs to get the pointer of rq and sq from db address
space of user and update it into qp context by modified qp. if rq does not
exist, it will not get the value from db address space of user.

Subject: [PATCH] scsi: hisi_sas: Fix NULL pointer dereference
Origin: https://git.kernel.org/linus/f4445bb93d82a984657b469e63118c2794a4c3d3
There is a NULL pointer dereference in case *slot* happens to be NULL at
lines 1053 and 1878:
struct hisi_sas_cq *cq =
&hisi_hba->cq[slot->dlvry_queue];
Notice that *slot* is being NULL checked at lines 1057 and 1881:
if (slot), which implies it may be NULL.
Fix this by placing the declaration and definition of variable cq, which
contains the pointer dereference slot->dlvry_queue, after slot has been
properly NULL checked.

Subject: [PATCH] scsi: hisi_sas: fix calls to dma_set_mask_and_coherent()
Origin: https://git.kernel.org/linus/d9a00459effc30f6de2cdd887b64f15c6c54ae71
The change to use dma_set_mask_and_coherent() incorrectly made a second
call with the 32 bit DMA mask value when the call with the 64 bit DMA
mask value succeeded.
