2023-11-17platform/x86/amd/pmc: adjust getting DRAM size behaviorShyam Sundar S K1-29/+2
amd_pmc_get_dram_size() is used to get the DRAM size information. But in the current code, mailbox command to get the DRAM size info is sent based on the values of dev->major and dev->minor. But dev->major and dev->minor will have either junk or zero assigned to them until at least once a call to amd_pmc_get_smu_version() is made which ideally populates dev->major and dev->minor. However, adding a amd_pmc_get_smu_version() call to amd_pmc_get_dram_size() has a downside of elevating the boot times. After talking to the PMFW team, it's understood that the "get dram size" mbox command would only be supported on specific platforms (like Mendocino) and not all. So, adjust getting DRAM size behavior such that, - if running on Rembrandt or Mendocino and the underlying PMFW knows how to execute the "get dram size" command it shall give the custom dram size. - if the underlying FW does not report the dram size, we just proceed further and assign the default dram size. The simplest way to address this is to remove amd_pmc_get_dram_size() function and directly call the "get dram size" command in the amd_pmc_s2d_init().

2023-11-17xen: privcmd: Replace zero-length array with flex-array member and use ↵Gustavo A. R. Silva1-1/+1
__counted_by Fake flexible arrays (zero-length and one-element arrays) are deprecated, and should be replaced by flexible-array members. So, replace zero-length array with a flexible-array member in `struct privcmd_kernel_ioreq`. Also annotate array `ports` with `__counted_by()` to prepare for the coming implementation by GCC and Clang of the `__counted_by` attribute. Flexible array members annotated with `__counted_by` can have their accesses bounds-checked at run-time via `CONFIG_UBSAN_BOUNDS` (for array indexing) and `CONFIG_FORTIFY_SOURCE` (for strcpy/memcpy-family functions). This fixes multiple -Warray-bounds warnings: drivers/xen/privcmd.c:1239:30: warning: array subscript i is outside array bounds of 'struct ioreq_port[0]' [-Warray-bounds=] drivers/xen/privcmd.c:1240:30: warning: array subscript i is outside array bounds of 'struct ioreq_port[0]' [-Warray-bounds=] drivers/xen/privcmd.c:1241:30: warning: array subscript i is outside array bounds of 'struct ioreq_port[0]' [-Warray-bounds=] drivers/xen/privcmd.c:1245:33: warning: array subscript i is outside array bounds of 'struct ioreq_port[0]' [-Warray-bounds=] drivers/xen/privcmd.c:1258:67: warning: array subscript i is outside array bounds of 'struct ioreq_port[0]' [-Warray-bounds=] This results in no differences in binary output.

2023-11-17swiotlb-xen: provide the "max_mapping_size" methodKeith Busch1-0/+1
There's a bug that when using the XEN hypervisor with bios with large multi-page bio vectors on NVMe, the kernel deadlocks [1]. The deadlocks are caused by inability to map a large bio vector - dma_map_sgtable always returns an error, this gets propagated to the block layer as BLK_STS_RESOURCE and the block layer retries the request indefinitely. XEN uses the swiotlb framework to map discontiguous pages into contiguous runs that are submitted to the PCIe device. The swiotlb framework has a limitation on the length of a mapping - this needs to be announced with the max_mapping_size method to make sure that the hardware drivers do not create larger mappings. Without max_mapping_size, the NVMe block driver would create large mappings that overrun the maximum mapping size.

2023-11-17afs: Make error on cell lookup failure consistent with OpenAFSDavid Howells1-2/+2
When kafs tries to look up a cell in the DNS or the local config, it will translate a lookup failure into EDESTADDRREQ whereas OpenAFS translates it into ENOENT. Applications such as West expect the latter behaviour and fail if they see the former. This can be seen by trying to mount an unknown cell: # mount -t afs %example.com:cell.root /mnt mount: /mnt: mount(2) system call failed: Destination address required.

Defer the generation of a PING RESPONSE ACK in response to a PING ACK until we've parsed the PING ACK so that we pick up any changes to the packet queue so that we can update ackinfo. This is also applied to an ACK generated in response to an ACK with the REQUEST_ACK flag set. Note that whilst the problem was added in commit 248f219cb8bc, it didn't really matter at that point because the ACK was proposed in softirq mode and generated asynchronously later in process context, taking the latest values at the time. But this fix is only needed since the move to parse incoming packets in an I/O thread rather than in softirq and generate the ACK at point of proposal (b0346843b1076b34a0278ff601f8f287535cb064).

2023-11-17s390/ism: ism driver implies smc protocolGerd Bayer2-48/+48
Since commit a72178cfe855 ("net/smc: Fix dependency of SMC on ISM") you can build the ism code without selecting the SMC network protocol. That leaves some ism functions be reported as unused. Move these functions under the conditional compile with CONFIG_SMC. Also codify the suggestion to also configure the SMC protocol in ism's Kconfig - but with an "imply" rather than a "select" as SMC depends on other config options and allow for a deliberate decision not to build SMC. Also, mention that in ISM's help.

2023-11-17rxrpc: Fix some minor issues with bundle tracingDavid Howells1-3/+4
Fix some superficial issues with the tracing of rxrpc_bundle structs, including: (1) Set the debug_id when the bundle is allocated rather than when it is set up so that the "NEW" trace line displays the correct bundle ID. (2) Show the refcount when emitting the "FREE" traceline. Signed-off-by: David Howells <[email protected]> cc: Marc Dionne <[email protected]> cc: "David S.

2023-11-16usb: aqc111: check packet for fixup for true limitOliver Neukum1-4/+4
If a device sends a packet that is inbetween 0 and sizeof(u64) the value passed to skb_trim() as length will wrap around ending up as some very large value. The driver will then proceed to parse the header located at that position, which will either oops or process some random value. The fix is to check against sizeof(u64) rather than 0, which the driver currently does. The issue exists since the introduction of the driver.

2023-11-16drm/msm/dp: attach the DP subconnector propertyDmitry Baryshkov1-0/+3
While developing and testing the commit bfcc3d8f94f4 ("drm/msm/dp: support setting the DP subconnector type") I had the patch [1] in my tree. I haven't noticed that it was a dependency for the commit in question. Mea culpa. Since the patch has not landed yet (and even was not reviewed) and since one of the bridges erroneously uses USB connector type instead of DP, attach the property directly from the MSM DP driver. This fixes the following oops on DP HPD event: drm_object_property_set_value (drivers/gpu/drm/drm_mode_object.c:288) dp_display_process_hpd_high (drivers/gpu/drm/msm/dp/dp_display.c:402) dp_hpd_plug_handle.isra.0 (drivers/gpu/drm/msm/dp/dp_display.c:604) hpd_event_thread (drivers/gpu/drm/msm/dp/dp_display.c:1110) kthread (kernel/kthread.c:388) ret_from_fork (arch/arm64/kernel/entry.S:858) [1] https://patchwork.freedesktop.org/patch/555530/ Fixes: bfcc3d8f94f4 ("drm/msm/dp: support setting the DP subconnector type") Reviewed-by: Abhinav Kumar <[email protected]> Signed-off-by: Dmitry Baryshkov <[email protected]> Tested-by: Jessica Zhang <[email protected]> # SC7280 Reviewed-by: Johan Hovold <[email protected]> Tested-by: Johan Hovold <[email protected]> Patchwork: https://patchwork.freedesktop.org/patch/564286/ Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Abhinav Kumar <[email protected]>

2023-11-16drm/msm/dpu: Add missing safe_lut_tbl in sc8280xp catalogBjorn Andersson1-0/+1
During USB transfers on the SC8280XP __arm_smmu_tlb_sync() is seen to typically take 1-2ms to complete. As expected this results in poor performance, something that has been mitigated by proposing running the iommu in non-strict mode (boot with iommu.strict=0). This turns out to be related to the SAFE logic, and programming the QOS SAFE values in the DPU (per suggestion from Rob and Doug) reduces the TLB sync time to below 10us, which means significant less time spent with interrupts disabled and a significant boost in throughput.

It seems during rebases I have left a call to drm_kms_helper_poll_init() which is not guarded by the (priv->kms_init) check. This leads to the crash for the boards which don't have KMS output.
