The logic behind changing the system page size because of what the Loongson kernel "prefers" is flawed. In the Loongson-2E manual, section 5.5, it is clear that the cpu supports a 4k page size (along with many others). Similarly for the Loongson-3 series CPUs, the 4k page size is mentioned in the section 7.7 (PageMask Register). Therefore we must continue to support a 4k page size.

Eventhough this does not cause any functional issue for AMD IOMMU driver since it normally uses information in the ACPI IVRS table to probe and initialize the device per recommendation in the AMD IOMMU specification, the device id zero causes the Windows Device Manager utility to show the device as an unknown device. Since Windows only recognizes AMD IOMMU device with device id 0x1419 as listed in the machine.inf file, modify the QEMU AMD IOMMU model to use the id 0x1419 to avoid the issue. This advertise the IOMMU as the AMD IOMMU device for Family 15h (Models 10h-1fh).

However, commit f3126d65, which was supposed to be a mere refactoring for scsi-disk.c, broke this and accidentally completed the SCSI request without considering the error policy any more if the error was signalled in the host_status field. Apart from the commit message not describing the change as intended, errors indicated in host_status are also obviously backend errors and not something the guest must deal with independently of the error policy. This behaviour means that some recoverable errors (such as a path error in multipath configurations) were reported to the guest anyway, which might not expect it and might consider its disk broken. Make sure that we apply the error policy again for host_status errors, too. This addresses an existing FIXME comment and allows us to remove some comments warning that callbacks weren't always called. With this fix, they are called in all cases again. The return value passed to the request callback doesn't have more free values that could be used to indicate host_status errors as well as SAM status codes and negative errno. Store the value in the host_status field of the SCSIRequest instead and use -ENODEV as the return value (if a path hasn't been reachable for a while, blk_aio_ioctl() will return -ENODEV instead of just setting host_status, so just reuse it here - it's not necessarily entirely accurate, but it's as good as any errno).

The script will not identify any dll dependencies for a QEMU build generated with clang. This in turn will fail the build, because there will be no files inside dlldir and no setup file will be created.

The goal was to remove the need to patch the (const) input buffer with a recomputed UDP checksum by copying headers to a RW region and inject the checksum there. The patch computed the checksum only from the header fields (missing the rest of the payload) producing an invalid one and making guests fail to acquire a DHCP lease.

This is because we call gen_goto_tb(dc, 1, ...) twice: brcond_i32 ZF,$0x0,ne,$L1 add_i32 pc,pc,$0x4 goto_tb $0x1 exit_tb $0x73d948001b81 set_label $L1 add_i32 pc,pc,$0x4 goto_tb $0x1 exit_tb $0x73d948001b81 Both calls are in arm_tr_tb_stop(), one for the DISAS_NEXT/DISAS_TOO_MANY handling, and one for the dc->condjump condition-failed codepath. The DISAS_NEXT handling doesn't have this problem because arm_post_translate_insn() does the handling of "emit the label for the condition-failed conditional execution" and so arm_tr_tb_stop() doesn't have dc->condjump set. But for DISAS_TOO_MANY we don't do that. Fix the bug by making arm_post_translate_insn() handle the DISAS_TOO_MANY case. This only affects the SB and ISB insns when used in Thumb mode inside an IT block: only these insns specifically set is_jmp to TOO_MANY, and their A32 encodings are unconditional. For the major TOO_MANY case (breaking the TB because it would cross a page boundary) we do that check and set is_jmp to TOO_MANY only after the call to arm_post_translate_insn(); so arm_post_translate_insn() sees is_jmp =3D=3D DISAS_NEXT, and we emit the correct code for that situation. With this fix we generate the somewhat more sensible set of TCG ops: brcond_i32 ZF,$0x0,ne,$L1 set_label $L1 add_i32 pc,pc,$0x4 goto_tb $0x1 exit_tb $0x7c5434001b81 (NB: the TCG optimizer doesn't optimize out the jump-to-next, but we can't really avoid emitting it because we don't know at the point we're emitting the handling for the condexec check whether this insn is going to happen to be a nop for us or not.)

Berrang=C3=A9 When gitlab initializes the repo checkout for a CI job, it will have done a shallow clone with only partial history. Periodically the objects that are omitted cause trouble with the check-patch/check-dco jobs. This is exhibited as reporting strange errors being unable to fetch certain objects that are known to exist. Passing the --refetch flag to 'git fetch' causes it to not assume the local checkout has all common objects and thus re-fetch everything that is needed. This appears to solve the check-patch/check-dco job failures. Signed-off-by: Daniel P. Berrang=C3=A9 Acked-by: Michael S.

However, the device model only sets the flag when I2C interrupts are enabled which causes U-Boot to loop forever. Fix the device model by always setting the flag and let I2C_I2CR[IIEN] guard I2C interrupts only. Also remove the comment in the code since it merely stated the obvious and would be outdated now.

Fix this by adding a simple boolean variable to ensure this function is only called once at a time. No synchronization needed for this boolean variable as this function is only entered and returned on main thread.

Reduce latency: This function calls v9fs_co_close() and v9fs_co_closedir() in a loop. Each one of the calls adds two thread hops (between main thread and a fs driver background thread). Each thread hop adds latency, which sums up in function's loop to a significant duration. Reduce overall latency by open coding what v9fs_co_close() and v9fs_co_closedir() do, executing those and the loop itself altogether in only one background thread block, hence reducing the total amount of thread hops to only two. 2. Fix file descriptor leak: The existing code called v9fs_co_close() and v9fs_co_closedir() to close file descriptors. Both functions check right at the beginning if the 9p request was cancelled: if (v9fs_request_cancelled(pdu)) { return -EINTR; } So if client sent a 'Tflush' message, v9fs_co_close() / v9fs_co_closedir() returned without having closed the file descriptor and v9fs_reclaim_fd() subsequently freed the FID without its file descriptor being closed, hence leaking those file descriptors. This 2nd bug is fixed by this patch as well by open coding v9fs_co_close() and v9fs_co_closedir() inside of v9fs_reclaim_fd() and not performing the v9fs_request_cancelled(pdu) check there.
