2024-06-23accel/habanalabs: move hl_eq_heartbeat_event_handle() to common codeTomer Tayar
hl_eq_heartbeat_event_handle() doesn't have ASIC specific code, and therefore can be moved from Gaudi2-only code to common code, and possibly used for other ASICs.

2024-06-23accel/habanalabs: add an EQ size ASIC propertyTomer Tayar
Future supported ASICs might use the dynamic EQ mechanism with the firmware, and in that case the EQ size won't be equal to the default HL_EQ_SIZE_IN_BYTES value.

2024-06-23accel/habanalabs: separate nonce from max_size in cpucp_packet structDani Liberman
In struct cpucp_packet both nonce and data_max_size members are in an union overlapping each other. This is a problem as they both are used in attestation and info_signed packets. The solution here is to move the nonce member to a different union under the same structure.

2024-06-23accel/habanalabs: check for errors after preboot is readyFarah Kassabri
Driver should check and report any fatal errors detected by preboot, before it attempts to load the boot fit. Some errors may cause the driver to stop the boot process and mark the device as unusable. This check will allow the driver to fail and print the error reported by preboot and skip the time wasting attempt of trying to load the boot fit, which will fail due to the error.

It is hard to debug the reason for heartbeat check failures. As an attempt to ease this task, this patch will provide more information when this failure happens.

2024-06-23accel/habanalabs/gaudi2: use single function to compare FW versionsOhad Sharabi
Currently, the code contains 2 types of FW version comparison functions: - hl_is_fw_sw_ver_[below/equal_or_greater]() - gaudi2 specific function of the type gaudi2_is_fw_ver_[below/above]x_y_z() Moreover, some functions use the inner FW version which shuold be only stage during development but not version dependencies. Finally, some tests are done to deprecated FW version to which LKD should hold no compatibility. This commit aligns all APIs to a single function that just compares the version and return an integers indicator (similar in some way to strcmp()). In addition, this generic function now considers also the sub-minor FW version and also remove dead code resulting in deprecated FW versions compatibility.

2024-06-23bcachefs: Fix btree_trans list orderingKent Overstreet
The debug code relies on btree_trans_list being ordered so that it can resume on subsequent calls or lock restarts. However, it was using trans->locknig_wait.task.pid, which is incorrect since btree_trans objects are cached and reused - typically by different tasks. Fix this by switching to pointer order, and also sort them lazily when required - speeding up the btree_trans_get() fastpath. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
2024-06-23bcachefs: Fix race between trans_put() and btree_transactions_read()Kent Overstreet
debug.c was using closure_get() on a different thread's closure where the we don't know if the object being refcounted is alive. We keep btree_trans objects on a list so they can be printed by debug code, and because it is cost prohibitive to touch the btree_trans list every time we allocate and free btree_trans objects, cached objects are also on this list. However, we do not want the debug code to see cached but not in use btree_trans objects - critically because the btree_paths array will have been freed (if it was reallocated). closure_get() is also incorrect to use when that get may race with it hitting zero, i.e. we must already have a ref on the object or know the ref can't currently hit 0 for other reasons (as used in the cycle detector). to fix this, use the previously introduced closure_get_not_zero(), closure_return_sync(), and closure_init_stack_release(); the debug code now can only take a ref on a trans object if it's alive and in use.

2024-06-22pwm: stm32: Fix calculation of prescalerUwe Kleine-König
A small prescaler is beneficial, as this improves the resolution of the duty_cycle configuration. However if the prescaler is too small, the maximal possible period becomes considerably smaller than the requested value. One situation where this goes wrong is the following: With a parent clock rate of 208877930 Hz and max_arr = 0xffff = 65535, a request for period = 941243 ns currently results in PSC = 1. The value for ARR is then calculated to ARR = 941243 * 208877930 / (1000000000 * 2) - 1 = 98301 This value is bigger than 65535 however and so doesn't fit into the respective register field. In this particular case the PWM was configured for a period of 313733.4806027616 ns (with ARR = 98301 & 0xffff). Even if ARR was configured to its maximal value, only period = 627495.6861167669 ns would be achievable. Fix the calculation accordingly and adapt the comment to match the new algorithm. With the calculation fixed the above case results in PSC = 2 and so an actual period of 941229.1667195285 ns.

2024-06-22ibmvnic: Free any outstanding tx skbs during scrq resetNick Child
There are 2 types of outstanding tx skb's: Type 1: Packets that are sitting in the drivers ind_buff that are waiting to be batch sent to the NIC. During a device reset, these are freed with a call to ibmvnic_tx_scrq_clean_buffer() Type 2: Packets that have been sent to the NIC and are awaiting a TX completion IRQ. These are free'd during a reset with a call to clean_tx_pools() During any reset which requires us to free the tx irq, ensure that the Type 2 skb references are freed. Since the irq is released, it is impossible for the NIC to inform of any completions. Furthermore, later in the reset process is a call to init_tx_pools() which marks every entry in the tx pool as free (ie not outstanding). So if the driver is to make a call to init_tx_pools(), it must first be sure that the tx pool is empty of skb references. This issue was discovered by observing the following in the logs during EEH testing: TX free map points to untracked skb (tso_pool 0 idx=4) TX free map points to untracked skb (tso_pool 0 idx=5) TX free map points to untracked skb (tso_pool 1 idx=36) Fixes: 65d6470d139a ("ibmvnic: clean pending indirect buffs during reset") Signed-off-by: Nick Child <nnac123@linux.ibm.com> Signed-off-by: David S.

2024-06-22counter: ti-eqep: enable clock at probeDavid Lechner
The TI eQEP clock is both a functional and interface clock. Since it is required for the device to function, we should be enabling it at probe. Up to now, we've just been lucky that the clock was enabled by something else on the system already.

Shigeru Yoshida's patch fixes a kernel information leak in j1939_send_one() in the j1939 protocol. Followed by a patch by Oleksij Rempel for the j1939 protocol, to properly recover from a CAN bus error during BAM transmission. A patch by Chen Ni properly propagates errors in the kvaser_usb driver.

2024-06-21vxlan: Pull inner IP header in vxlan_xmit_one().Guillaume Nault
Ensure the inner IP header is part of the skb's linear data before setting old_iph. Otherwise, on a non-linear skb, old_iph could point outside of the packet data. Unlike classical VXLAN, which always encapsulates Ethernet packets, VXLAN-GPE can transport IP packets directly. In that case, we need to look at skb->protocol to figure out if an Ethernet header is present.
