[PATCH v3 1/2] drm/xe: Use non-interruptible wait when moving BO to system

by Nirmoy Das

Ensure a non-interruptible wait is used when moving a bo to XE_PL_SYSTEM. This prevents dma_mappings from being removed prematurely while a GPU job is still in progress, even if the CPU receives a signal during the operation.

[PATCH AUTOSEL 6.12 01/19] s390/pci: Sort PCI functions prior to creating virtual busses

by Sasha Levin

From: Niklas Schnelle <schnelle(a)linux.ibm.com> [ Upstream commit 0467cdde8c4320bbfdb31a8cff1277b202f677fc ] Instead of relying on the observed but not architected firmware behavior that PCI functions from the same card are listed in ascending RID order in clp_list_pci() ensure this by sorting. To allow for sorting separate the initial clp_list_pci() and creation of the virtual PCI busses. Note that fundamentally in our per-PCI function hotplug design non RID order of discovery is still possible. For example when the two PFs of a two port NIC are hotplugged after initial boot and in descending RID order. In this case the virtual PCI bus would be created by the second PF using that PF's UID as domain number instead of that of the first PF. Thus the domain number would then change from the UID of the second PF to that of the first PF on reboot but there is really nothing we can do about that since changing domain numbers at runtime seems even worse. This only impacts the domain number as the RIDs are consistent and thus even with just the second PF visible it will show up in the correct position on the virtual bus.

[PATCH AUTOSEL 6.11 01/15] usb: chipidea: add CI_HDRC_HAS_SHORT_PKT_LIMIT flag

by Sasha Levin

From: Xu Yang <xu.yang_2(a)nxp.com> [ Upstream commit ec841b8d73cff37f8960e209017efe1eb2fb21f2 ] Currently, the imx deivice controller has below limitations: 1. can't generate short packet interrupt if IOC not set in dTD. So if one request span more than one dTDs and only the last dTD set IOC, the usb request will pending there if no more data comes. 2. the controller can't accurately deliver data to differtent usb requests in some cases due to short packet. For example: one usb request span 3 dTDs, then if the controller received a short packet the next packet will go to 2nd dTD of current request rather than the first dTD of next request. 3. can't build a bus packet use multiple dTDs. For example: controller needs to send one packet of 512 bytes use dTD1 (200 bytes) + dTD2 (312 bytes), actually the host side will see 200 bytes short packet. Based on these limits, add CI_HDRC_HAS_SHORT_PKT_LIMIT flag and use it on imx platforms.

In this case a small negative offset returns approximately 4.29 seconds (~ 2^32/1000 milliseconds) due to the unsigned cast of the negative offset. This cast was added when the kernel internal struct timex was changed to use type long long for the time offset value to address the problem of a 64bit/32bit division on 32bit systems. The correct cast would have been (s32), which is correct as time_offset can only be in the range of [INT_MIN..INT_MAX] because the shift constant used for calculating it is 32. But that's non-obvious. Remove the cast and use div_s64() to cure the issue.
