* hw/arm/virt: KVM: Probe for KVM_CAP_ARM_VM_IPA_SIZE when creating scratch VMMarc Zyngier2021-09-131-1/+6
| | | | | | | | | | | | | | | | | | | | | Although we probe for the IPA limits imposed by KVM (and the hardware) when computing the memory map, we still use the old style '0' when creating a scratch VM in kvm_arm_create_scratch_host_vcpu(). On systems that are severely IPA challenged (such as the Apple M1), this results in a failure as KVM cannot use the default 40bit that '0' represents. Instead, probe for the extension and use the reported IPA limit if available.

* hw/char: cadence_uart: Log a guest error when device is unclocked or in resetBin Meng2021-09-131-0/+8
| | | | | | | | | | | | | | | | | | We've got SW that expects FSBL (Bootlooader) to setup clocks and resets. It's quite common that users run that SW on QEMU without FSBL (FSBL typically requires the Xilinx tools installed). That's fine, since users can stil use -device loader to enable clocks etc. To help folks understand what's going, a log (guest-error) message would be helpful here. In particular with the serial port since things will go very quiet if they get things wrong. Suggested-by: Edgar E.

* hw/misc: zynq_slcr: Correctly compute output clocks in the reset exit phaseBin Meng2021-09-131-13/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | As of today, when booting upstream U-Boot for Xilinx Zynq, the UART does not receive anything. Debugging shows that the UART input clock frequency is zero which prevents the UART from receiving anything as per the logic in uart_receive(). From zynq_slcr_reset_exit() comment, it intends to compute output clocks according to ps_clk and registers. zynq_slcr_compute_clocks() is called to accomplish the task, inside which device_is_in_reset() is called to actually make the attempt in vain. Rework reset_hold() and reset_exit() so that in the reset exit phase, the logic can really compute output clocks in reset_exit(). With this change, upstream U-Boot boots properly again with: $ qemu-system-arm -M xilinx-zynq-a9 -m 1G -display none -serial null -serial stdio \ -device loader,file=u-boot-dtb.bin,addr=0x4000000,cpu-num=0 Fixes: 38867cb7ec90 ("hw/misc/zynq_slcr: add clock generation for uarts") Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Alistair Francis <alistair.francis@wdc.com> Reviewed-by: Edgar E.

This is for static binaries only, that are relatively small, but it's better than the 100% instant mmap failre that is the current state of all things bsd-user in upstream qemu. Future patch sets will refine this, add the missing system calls, fix bugs preventing more sophisticated programms from running and add a bunch of new architecture support. There's three large themes in these patches, though the changes that represent them are interrelated making it hard to separate out further. 1. Reorganization to support multiple OS and architectures (though I've only tested FreeBSD, other BSDs might not even compile yet). 2. Diff reduction with the bsd-user fork for several files. These diffs include changes that borrowed from linux-user as well as changes to make things work on FreeBSD. The records keeping when this was done, however, was poor at best, so many of the specific borrowings are going unacknowledged here, apart from this general ack. These diffs also include some minor code shuffling. Some of the changes are done specifically to make it easier to rebase the bsd-user fork's changes when these land in the tree (a number of changes have been pushed there to make this more possible). 3. Filling in the missing pieces to make things work. There's many changes to elfload to make it load things in the right places, to find the interpreter better, etc. There's changes to mmap.c to make the mappings work better and there's changes to main.c that were inspired, at least, by now-ancient changes to linux-user's main.c. I ran checkpatch.pl on this, and there's 350-odd errors it identifies (the vast majoirty come from BSD's fetish for tabs), so there will need to be a V2 to fix this at the very least. In addition, the change set is big (about +~4.5k/-~2.5k lines), so I anticipate some iteration as well just based on its sheer size. I've tried to keep each set small to make it easy to review in isolation, but I've also allowed some interrelated ones to get a little bigger than I'd normally like. I've not done the customary documentation of the expected checkpatch.pl output because it is large, and because I wanted to get review of the other parts rolling to get this project unstuck. Future versions of the patch will document the expected output. In addition, I noticed a number of places where I could modernize to make the code match things like linux-user better. I've resisted the urge to do these at this time, since it would complicate merging the other ~30k lines of diff that remains after this batch. Future batches should generally be smaller once this one has landed since they are, by and large, either a bunch of new files to support armv7, aarch64, riscv64, mips, mipsel, mips64, ppc, ppc64 and ppc64le, or are adding system calls, which can be done individually or small groups. I've removed sparc and sparc64 support as they've been removed from FreeBSD and have been near totally busted for years. Stacey Son did the bulk of this work originally, but since I had to move things around so much and/or retool that work in non-trivial ways, I've kept myself as author, and added his signed-off-by line. I'm unsure of the qemu standard practice for this, but am happy to learn if this is too far outside its current mainstream. For a while Sean Bruno did the merges from upstream, and he's credited using his signed-off-by in appropriate places, though for this patch set there's only a few. I've tried to ensure that others who have work in individual patches that I've aggregated together also are reflected in their signed-off-by. Given the chaotic stat of the upstream repo for its early history, this may be the best that can be reconstructed at this late date. Most of these files are 'foundational' so have existed from the earliest days when record keeping wasn't quite what I'd wish for in hindsight. There was only really one change that I could easily cherry-pick (Colin's), so I did that. # gpg: Signature made Fri 10 Sep 2021 21:24:08 BST # gpg: using RSA key 2035F894B00AA3CF7CCDE1B76C1CD1287DB01100 # gpg: Good signature from "Warner Losh <wlosh@netflix.com>" [unknown] # gpg: aka "Warner Losh <imp@bsdimp.com>" [unknown] # gpg: aka "Warner Losh <imp@freebsd.org>" [unknown] # gpg: aka "Warner Losh <imp@village.org>" [unknown] # gpg: aka "Warner Losh <wlosh@bsdimp.com>" [unknown] # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: 2035 F894 B00A A3CF 7CCD E1B7 6C1C D128 7DB0 1100 * remotes/bsdimp/tags/pull-bsd-user-20210910: (42 commits) bsd-user: Update mapping to handle reserved and starting conditions bsd-user: Add '-0 argv0' option to bsd-user/main.c bsd-user: Implement interlock for atomic operations bsd-user: move gemu_log to later in the file bsd-user: Refactor load_elf_sections and is_target_elf_binary bsd-user: elfload.c style catch up patch bsd-user: add stubbed out core dump support bsd-user: Add target_os_user.h to capture the user/kernel structures bsd-user: Add target_arch_reg to describe a target's register set bsd-user: update debugging in mmap.c bsd-user: Rewrite target system call definintion glue bsd-user: Remove dead #ifdefs from elfload.c bsd-user: elf cleanup bsd-user: Add architecture specific signal tramp code bsd-user: Move stack initializtion into a per-os file. bsd-user: Implement --seed and initialize random state bsd-user: *BSD specific siginfo defintions bsd-user: Add system independent stack, data and text limiting bsd-user: Create target specific vmparam.h bsd-user: define max args in terms of pages ...

Create thread_os_thread.h to hold the os specific parts of the thread and threat manipulation routines. Currently, it just includes target_arch_thread.h. target_arch_thread.h contains the at the moment unused target_thread_set_upcall which will be used in the future when creating actual thread (i386 has this stubbed, but other architectures in the bsd-user tree have real ones). FreeBSD doesn't do AT_HWCAP, so remove that code. Linux does, and this code came from there. These changes are all interrelated and could be brokend down, but seem to represent a reviewable changeset since most of the change is boiler plate.
