2024-07-15dt-bindings: thermal: mediatek: Fix thermal zone definitions for MT8188Julien Panis2-10/+10
Fix thermal zone names for consistency with the other SoCs: - GPU0 must be used as the first GPU item. - SOCx deal with audio DSP, video, and infra subsystems. The naming must be fixed "atomically" so compilation does not break. As a result, the change is made in the dt-bindings and in the LVTS driver within a single commit, despite the checkpatch warning. The definitions can be safely modified here because they are used only in the LVTS driver, which is modified accordingly, and have not yet been included in a released kernel.

2024-07-15thermal/drivers/k3_j72xx_bandgap: Implement suspend/resume supportThéo Lebrun1-33/+78
This add suspend-to-ram support. The derived_table is kept-as is, so the resume is only about pm_runtime_* calls and restoring the same registers as the probe. Extract the hardware initialization procedure to a function called at both probe-time & resume-time. The probe-time loop is split in two to ensure doing the hardware initialization before registering thermal zones. That ensures our callbacks cannot be called while in bad state. The 100ms delay in the hardware initialization sequence was removed. It was initially added to be sure the thresholds are programmed before enabling the interrupt, but in fact it's not needed (tested on J7200 platform).

2024-07-14workqueue: Always queue work items to the newest PWQ for order workqueuesLai Jiangshan1-1/+5
To ensure non-reentrancy, __queue_work() attempts to enqueue a work item to the pool of the currently executing worker. This is not only unnecessary for an ordered workqueue, where order inherently suggests non-reentrancy, but it could also disrupt the sequence if the item is not enqueued on the newest PWQ. Just queue it to the newest PWQ and let order management guarantees non-reentrancy.

2024-07-14xdp: fix invalid wait context of page_pool_destroy()Taehee Yoo1-3/+1
If the driver uses a page pool, it creates a page pool with page_pool_create(). The reference count of page pool is 1 as default. A page pool will be destroyed only when a reference count reaches 0. page_pool_destroy() is used to destroy page pool, it decreases a reference count. When a page pool is destroyed, ->disconnect() is called, which is mem_allocator_disconnect(). This function internally acquires mutex_lock(). If the driver uses XDP, it registers a memory model with xdp_rxq_info_reg_mem_model(). The xdp_rxq_info_reg_mem_model() internally increases a page pool reference count if a memory model is a page pool. Now the reference count is 2. To destroy a page pool, the driver should call both page_pool_destroy() and xdp_unreg_mem_model(). The xdp_unreg_mem_model() internally calls page_pool_destroy(). Only page_pool_destroy() decreases a reference count. If a driver calls page_pool_destroy() then xdp_unreg_mem_model(), we will face an invalid wait context warning. Because xdp_unreg_mem_model() calls page_pool_destroy() with rcu_read_lock(). The page_pool_destroy() internally acquires mutex_lock().

Using xa without rcu_read_lock() here is safe. xa is freed by __xdp_mem_allocator_rcu_free() and this is called by call_rcu() of mem_xa_remove(). The mem_xa_remove() is called by page_pool_destroy() if a reference count reaches 0. The xa is already protected by the reference count mechanism well in the control plane. So removing rcu_read_lock() for page_pool_destroy() is safe. Fixes: c3f812cea0d7 ("page_pool: do not release pool until inflight == 0.")

There is only subset of capabilities supported because of limited collection of hardware available for the development. For BroadR-Reach capable PHYs, the LRE (Long Reach Ethernet) alternative register set is handled. Only bcm54811 PHY is verified, for bcm54810, there is some support possible but untested. There is no auto-negotiation of the link parameters (called LDS in the Broadcom terminology, Long-Distance Signaling) for bcm54811. It should be possible to enable LDS for bcm54810.

Xuan Zhuo says: ==================== virtio-net: support AF_XDP zero copy v5: http://lore.kernel.org/all/[email protected] XDP socket(AF_XDP) is an excellent bypass kernel network framework. The zero copy feature of xsk (XDP socket) needs to be supported by the driver. The performance of zero copy is very good. mlx5 and intel ixgbe already support this feature, This patch set allows virtio-net to support xsk's zerocopy xmit feature. At present, we have completed some preparation: 1. vq-reset (virtio spec and kernel code) 2. virtio-core premapped dma 3. virtio-net xdp refactor So it is time for Virtio-Net to complete the support for the XDP Socket Zerocopy. Virtio-net can not increase the queue num at will, so xsk shares the queue with kernel. On the other hand, Virtio-Net does not support generate interrupt from driver manually, so when we wakeup tx xmit, we used some tips. If the CPU run by TX NAPI last time is other CPUs, use IPI to wake up NAPI on the remote CPU. If it is also the local CPU, then we wake up napi directly. This patch set includes some refactor to the virtio-net to let that to support AF_XDP. Because there are too many commits, the work of virtio net supporting af-xdp is split to rx part and tx part. This patch set is for rx part. So the flag NETDEV_XDP_ACT_XSK_ZEROCOPY is not added, if someone want to test for af-xdp rx, the flag needs to be adding locally.

But here we should use the macro XDP_PACKET_HEADROOM from bpf.h to calculate the headroom for xdp. So here we remove the VIRTIO_XDP_HEADROOM, and use the XDP_PACKET_HEADROOM to replace it.

2024-07-14af_packet: Handle outgoing VLAN packets without hardware offloadingChengen Du1-2/+84
The issue initially stems from libpcap. The ethertype will be overwritten as the VLAN TPID if the network interface lacks hardware VLAN offloading. In the outbound packet path, if hardware VLAN offloading is unavailable, the VLAN tag is inserted into the payload but then cleared from the sk_buff struct. Consequently, this can lead to a false negative when checking for the presence of a VLAN tag, causing the packet sniffing outcome to lack VLAN tag information (i.e., TCI-TPID). As a result, the packet capturing tool may be unable to parse packets as expected. The TCI-TPID is missing because the prb_fill_vlan_info() function does not modify the tp_vlan_tci/tp_vlan_tpid values, as the information is in the payload and not in the sk_buff struct. The skb_vlan_tag_present() function only checks vlan_all in the sk_buff struct. In cooked mode, the L2 header is stripped, preventing the packet capturing tool from determining the correct TCI-TPID value. Additionally, the protocol in SLL is incorrect, which means the packet capturing tool cannot parse the L3 header correctly.

There is more NR_CPUS usage in the fsl-qbman driver, but that looks relatively harmless and I couldn't find a good reason to change it. I noticed, while testing, that the driver doesn't actually work properly with high CONFIG_NR_CPUS values, and patch 2/5 addresses that. During code analysis, I have identified two places which treat conditions that can never happen. Patches 3/5 and 4/5 simplify the probing code - dpaa_fq_setup() - just a little bit. Finally we have at 5/5 the patch that triggered all of this.

2024-07-14net: dpaa: no need to make sure all CPUs receive a corresponding Tx queueVladimir Oltean1-11/+0
dpaa_fq_setup() iterates through the &priv->dpaa_fq_list elements allocated by dpaa_alloc_all_fqs(). This includes a call to: if (!dpaa_fq_alloc(dev, 0, dpaa_max_num_txqs(), list, FQ_TYPE_TX)) goto fq_alloc_failed; which gives us dpaa_max_num_txqs() elements of FQ_TYPE_TX type. The code block which we are deleting runs after an earlier iteration through &priv->dpaa_fq_list. So at the end of this iteration (for which there is no early break), egress_cnt will be unconditionally equal to dpaa_max_num_txqs(). In other words, dpaa_alloc_all_fqs() has already allocated TX queues for all possible CPUs and the maximal number of traffic classes, and we've already iterated once through them all. The while() condition is dead code, remove it.

dpaa_fq_setup() iterates through the queues allocated by dpaa_alloc_all_fqs() and saved in &priv->dpaa_fq_list. The allocation for FQ_TYPE_TX looks as follows: if (!dpaa_fq_alloc(dev, 0, dpaa_max_num_txqs(), list, FQ_TYPE_TX)) goto fq_alloc_failed; Thus, iterating again through FQ_TYPE_TX queues in dpaa_fq_setup() and counting them will never yield an egress_cnt larger than the allocated size, dpaa_max_num_txqs(). The comparison serves no purpose since it is always true; remove it.

2024-07-14net: dpaa: eliminate NR_CPUS dependency in egress_fqs[] and conf_fqs[]Vladimir Oltean2-20/+47
The driver uses the DPAA_TC_TXQ_NUM and DPAA_ETH_TXQ_NUM macros for TX queue handling, and they depend on CONFIG_NR_CPUS. In generic .config files, these can go to very large (8096 CPUs) values for the systems that DPAA1 is integrated in (1-24 CPUs). We allocate a lot of resources that will never be used. Those are: - system memory - QMan FQIDs as managed by qman_alloc_fqid_range(). This is especially painful since currently, when booting with CONFIG_NR_CPUS=8096, a LS1046A-RDB system will only manage to probe 3 of its 6 interfaces. The rest will run out of FQD ("/reserved-memory/qman-fqd" in the device tree) and fail at the qman_create_fq() stage of the probing process. - netdev queues as alloc_etherdev_mq() argument. The high queue indices are simply hidden from the network stack after the call to netif_set_real_num_tx_queues(). With just a tiny bit more effort, we can replace the NR_CPUS compile-time constant with the num_possible_cpus() run-time constant, and dynamically allocate the egress_fqs[] and conf_fqs[] arrays. Even on a system with a high CONFIG_NR_CPUS, num_possible_cpus() will remain equal to the number of available cores on the SoC. The replacement is as follows: - DPAA_TC_TXQ_NUM -> dpaa_num_txqs_per_tc() - DPAA_ETH_TXQ_NUM -> dpaa_max_num_txqs() Signed-off-by: Vladimir Oltean <[email protected]> Acked-by: Madalin Bucur <[email protected]> Link: https://patch.msgid.link/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>
2024-07-14net: dpaa: avoid on-stack arrays of NR_CPUS elementsVladimir Oltean2-6/+24
The dpaa-eth driver is written for PowerPC and Arm SoCs which have 1-24 CPUs. It depends on CONFIG_NR_CPUS having a reasonably small value in Kconfig. Otherwise, there are 2 functions which allocate on-stack arrays of NR_CPUS elements, and these can quickly explode in size, leading to warnings such as: drivers/net/ethernet/freescale/dpaa/dpaa_eth.c:3280:12: warning: stack frame size (16664) exceeds limit (2048) in 'dpaa_eth_probe' [-Wframe-larger-than] The problem is twofold: - Reducing the array size to the boot-time num_possible_cpus() (rather than the compile-time NR_CPUS) creates a variable-length array, which should be avoided in the Linux kernel. - Using NR_CPUS as an array size makes the driver blow up in stack consumption with generic, as opposed to hand-crafted, .config files. A simple solution is to use dynamic allocation for num_possible_cpus() elements (aka a small number determined at runtime).

2024-07-14Bluetooth: btnxpuart: Add handling for boot-signature timeout errorsNeeraj Sanjay Kale1-4/+48
This handles the timeout error codes sent by the chip as part of the bootloader signatures during firmware download process. When the bootloader does not receive a response packet from the host within a specific time, it adds an error code to the bootloader signature while requesting for the FW chunk from the same offset. The host is expected to clear this error code with a NAK, and reply to only those bootloader signatures which have error code 0. However, the driver was ignoring this error code and replying with the firmware chunks instead, which is apparently ignored by the chip and the chip resends the same bootloader signature with the error code again. This happens in a loop until the error code self clears and firmware download proceeds ahead, adding a couple of milliseconds to the total firmware download time. Commit 689ca16e5232 was an initial implementation which simply printed the following line during driver debug: - FW Download received err 0x04 from chip This commit adds the expected handling to the error codes. This error handling is valid for data_req bootloader signatures for V3 and future bootloader versions.
