2023-02-10platform/x86/amd: pmc: Add num_samples message id support to STBShyam Sundar S K
Recent PMFWs have the support for S2D_NUM_SAMPLES message ID that can tell the current number of samples present within the STB DRAM. num_samples returned would let the driver know the start of the read from the last push location. This way, the driver would emit the top most region of the STB DRAM.

2023-02-10drm/ast: Fix start address computationJocelyn Falempe
During the driver conversion to shmem, the start address for the scanout buffer was set to the base PCI address. In most cases it works because only the lower 24bits are used, and due to alignment it was almost always 0. But on some unlucky hardware, it's not the case, and some uninitialized memory is displayed on the BMC. With shmem, the primary plane is always at offset 0 in GPU memory. * v2: rewrite the patch to set the offset to 0. (Thomas Zimmermann) * v3: move the change to plane_init() and also fix the cursor plane. (Jammy Huang) Tested on a sr645 affected by this bug.

2023-02-10crypto: qat - drop log level of msg in get_instance_node()Giovanni Cabiddu
The functions qat_crypto_get_instance_node() and qat_compression_get_instance_node() allow to get a QAT instance (ring pair) on a device close to the node specified as input parameter. When this is not possible, and a QAT device is available in the system, these function return an instance on a remote node and they print a message reporting that it is not possible to find a device on the specified node. This is interpreted by people as an error rather than an info. The print "Could not find a device on node" indicates that a kernel application is running on a core in a socket that does not have a QAT device directly attached to it and performance might suffer. Due to the nature of the message, this can be considered as a debug message, therefore drop the severity to debug and report it only once to avoid flooding.

2023-02-10crypto: qat - fix out-of-bounds readGiovanni Cabiddu
When preparing an AER-CTR request, the driver copies the key provided by the user into a data structure that is accessible by the firmware. If the target device is QAT GEN4, the key size is rounded up by 16 since a rounded up size is expected by the device. If the key size is rounded up before the copy, the size used for copying the key might be bigger than the size of the region containing the key, causing an out-of-bounds read. Fix by doing the copy first and then update the keylen. This is to fix the following warning reported by KASAN: [ 138.150574] BUG: KASAN: global-out-of-bounds in qat_alg_skcipher_init_com.isra.0+0x197/0x250 [intel_qat] [ 138.150641] Read of size 32 at addr ffffffff88c402c0 by task cryptomgr_test/2340 [ 138.150651] CPU: 15 PID: 2340 Comm: cryptomgr_test Not tainted 6.2.0-rc1+ #45 [ 138.150659] Hardware name: Intel Corporation ArcherCity/ArcherCity, BIOS EGSDCRB1.86B.0087.D13.2208261706 08/26/2022 [ 138.150663] Call Trace: [ 138.150668] <TASK> [ 138.150922] kasan_check_range+0x13a/0x1c0 [ 138.150931] memcpy+0x1f/0x60 [ 138.150940] qat_alg_skcipher_init_com.isra.0+0x197/0x250 [intel_qat] [ 138.151006] qat_alg_skcipher_init_sessions+0xc1/0x240 [intel_qat] [ 138.151073] crypto_skcipher_setkey+0x82/0x160 [ 138.151085] ? prepare_keybuf+0xa2/0xd0 [ 138.151095] test_skcipher_vec_cfg+0x2b8/0x800 Fixes: 67916c951689 ("crypto: qat - add AES-CTR support for QAT GEN4 devices") Cc: <stable@vger.kernel.org> Reported-by: Vladis Dronov <vdronov@redhat.com> Signed-off-by: Giovanni Cabiddu <giovanni.cabiddu@intel.com> Reviewed-by: Fiona Trahe <fiona.trahe@intel.com> Reviewed-by: Vladis Dronov <vdronov@redhat.com> Tested-by: Vladis Dronov <vdronov@redhat.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2023-02-10net: ipa: start generalizing "ipa_reg"Alex Elder
IPA register definitions have evolved with each new version. The changes required to support more than 32 endpoints in IPA v5.0 made it best to define a unified mechanism for defining registers and their fields. GSI register definitions, meanwhile, have remained fairly stable. And even as the total number of IPA endpoints goes beyond 32, the number of GSI channels on a given EE that underly endpoints still remains 32 or less. Despite that, GSI v3.0 (which is used with IPA v5.0) extends the number of channels (and events) it supports to be about 256, and as a result, many GSI register definitions must change significantly. To address this, we'll use the same "ipa_reg" mechanism to define the GSI registers. As a first step in generalizing the "ipa_reg" to also support GSI registers, isolate the definitions of the "ipa_reg" and "ipa_regs" structure types (and some supporting macros) into a new header file, and remove the "ipa_" and "IPA_" from symbol names. Separate the IPA register ID validity checking from the generic check that a register ID is in range. Aside from that, this is intended to have no functional effect on the code.

Similarly, the global and general GSI interrupt types each has a set of conditions it signals, and both types have an enumerated type that defines which bit that represents each condition. When used, these enumerated values are passed as an argument to BIT() in *all* cases. So clean up the code a little bit by defining the enumerated type values as one-bit masks rather than bit positions. Rename gsi_general_id to be gsi_general_irq_id for consistency.

2023-02-09nfp: fix schedule in atomic context when offloading saYinjun Zhang
IPsec offloading callbacks may be called in atomic context, sleep is not allowed in the implementation. Now use workqueue mechanism to avoid this issue. Extend existing workqueue mechanism for multicast configuration only to universal use, so that all configuring through mailbox asynchronously can utilize it.

2023-02-09nfp: fix incorrect use of mbox in IPsec codeYinjun Zhang
The mailbox configuration mechanism requires writing several registers, which shouldn't be interrupted, so need lock to avoid race condition. The base offset of mailbox configuration registers is not fixed, it depends on TLV caps read from application firmware.

2023-02-09net: bgmac: fix BCM5358 support by setting correct flagsRafał Miłecki
Code blocks handling BCMA_CHIP_ID_BCM5357 and BCMA_CHIP_ID_BCM53572 were incorrectly unified. Chip package values are not unique and cannot be checked independently. They are meaningful only in a context of a given chip. Packages BCM5358 and BCM47188 share the same value but then belong to different chips. Code unification resulted in treating BCM5358 as BCM47188 and broke its initialization.

2023-02-09nfp: support IPsec offloading for NFP3800Huanhuan Wang
Add IPsec offloading support for NFP3800. Include data plane and control plane. Data plane: add IPsec packet process flow in NFP3800 datapath (NFDk). Control plane: add an algorithm support distinction flow in xfrm hook function xdo_dev_state_add(), as NFP3800 has a different set of IPsec algorithm support. This matches existing support for the NFP6000/NFP4000 and their NFD3 datapath. In addition, fixup the md_bytes calculation for NFD3 datapath to make sure the two datapahts are keept in sync.

Add driver to enable PCIe board which uses XDMA (the DMA/Bridge Subsystem for PCI Express). For example, Xilinx Alveo PCIe devices. https://www.xilinx.com/products/boards-and-kits/alveo.html The XDMA engine support up to 4 Host to Card (H2C) and 4 Card to Host (C2H) channels. Memory transfers are specified on a per-channel basis in descriptor linked lists, which the DMA fetches from host memory and processes. Events such as descriptor completion and errors are signaled using interrupts. The hardware detail is provided by https://docs.xilinx.com/r/en-US/pg195-pcie-dma/Introduction This driver implements dmaengine APIs. - probe the available DMA channels - use dma_slave_map for channel lookup - use virtual channel to manage dmaengine tx descriptors - implement device_prep_slave_sg callback to handle host scatter gather list - implement device_config to config device address for DMA transfer Signed-off-by: Lizhi Hou <lizhi.hou@amd.com> Signed-off-by: Sonal Santan <sonal.santan@amd.com> Signed-off-by: Max Zhen <max.zhen@amd.com> Signed-off-by: Brian Xu <brian.xu@amd.com> Tested-by: Martin Tuma <tumic@gpxsee.org> Link: https://lore.kernel.org/r/1674145926-29449-2-git-send-email-lizhi.hou@amd.com Signed-off-by: Vinod Koul <vkoul@kernel.org>
