Giant Panda Numbers Are Surging--or Are They?

5 hours ago May 18, 2007 . A population doubling at Wanglang is impossible, argues Wang Dajun, a panda researcher at Peking University, because habitat there shrank steadily until at least 1998, when the logging ban was enacted. By comparing satellite images from 1990 and 2000, Wang quantified a heavy degree of deforestation that, he says, must be harmful to pandas.

• AndrewFasano commented Mar 20, 2020 • edited commented • edited We've been talking about this for a bit but haven't started work on it. Creating this issue to track progress. We're currently forked off of Qemu at version 2.9.1. We should update to 4+. At the time of writing, the latest version if 4.1. We'll likely need to disable MTTCG to avoid significantly changing the record/replay model. The main tasks I see for now are: Actually do the git merge and handle merge conflicts to create a (likely broken) branch with all the commits Get callbacks to run Capture correct recordings Replay recordings correctly Library mode: build qemu as a library Pypanda testing Extensive testing The text was updated successfully, but these errors were encountered: 🎉 3 added this to the milestone Copy link Contributor
• janbbeck commented Mar 23, 2020 commented Just to give it my 2 cents: I recently upgraded qira from qemu 2.x to qemu 4.0 instead of 4.1. At least for that effort, the changes after 4.0 were getting so severe that porting to 4.0 before going to 4.1 made sense. This may, of course, not be true for PANDA, but it may be easier to port PANDA to some intermediate version of qemu than going to 4.1 all at once. 👍 1 Sorry, something went wrong.

• hanetzer commented Mar 24, 2020 commented judging by the amount of monkeypatching I needed to do to get pandas as it currently exists to build on my system, I almost think it would be easier to collect what is different between pandas and the qemu version its based on and just rewrite it against qemu4.

• janbbeck commented Mar 25, 2020 commented fwiw, panda builds just fine for me with gcc 7 8 ad 9 under ubuntu 19.04, as long as werror is suppressed. no monkeying necessary, using this type of configure: ./configure --target-list=x86_64-softmmu,i386-softmmu,arm-softmmu,ppc-softmmu --prefix=/home/jan/Downloads/panda/panda/scripts/panda/build/install --python=/usr/bin/python2 --disable-vhost-net --extra-cflags=-DXC_WANT_COMPAT_DEVICEMODEL_API --extra-cflags=-DOSI_PROC_EVENTS --extra-cflags=-DOSI_MAX_PROC=256 --extra-cflags=-DOSI_LINUX_PSDEBUG --extra-cflags=-Wformat-truncation=0 --disable-werror --cc=gcc-9 --cxx=g++-9 --host-cc=gcc-9 just change to compiler of your choice. I just rebuilt panda with gcc 7, 8 and 9 and booted each time into a ubuntu live dvd and noticed no issues. HTH 👍 1 Sorry, something went wrong. Copy link Contributor
• mariusmue commented Mar 26, 2020 • edited commented • edited Hi all, In my opinion, an update to a newer version of Qemu benefits foremost emulation and analysis of non x86-based systems. As mentioned, there are just more machines, as well as architectures implemented. Furthermore, when it comes to avatar-related changes, being on modern versions of QEMU would it make easier to sync changes between the two frameworks, but this is just a minor point. MTTCG is luckily guarded well behind preprocessor macros, so it should be easy to keep it deactivated. Furthermore, I think somewhen around qemu 3.0 was a tremendous change/cleanup in the QAPI, I personally like the new organization better. When it comes to tcg-plugins, yes, they are great for passive monitoring of VMState. In case PANDA wants to enforce a strict separation between record and analysis, I would suggest that recording is re-implemented on top of this API (if possible), as this would allow recording on stock-builds of qemu as drop-in solution. In theory, this should even allow for records independent of the QEMU version, but I think there may various problems arise in praxis. (E.g., different peripheral implementations.) In any case, the actual analysis/replay instances of PANDA would still need to hook at various in the codebase, but distinguishing whether we are in record or replay mode should be an artifact of the past, allowing for a cleaner codebase, easier to migrate to upcoming versions of qemu as well. Hence, if these changes are going to happen, I would not plead for a complete rewrite of PANDA, but for identifying and minimizing the locations PANDA actually hooks into QEMU's core logic. 👍 3 Sorry, something went wrong. mentioned this issue Closed mentioned this issue Closed Copy link
• glueckself commented Apr 10, 2020 commented I'm merging Qemu 5.0 rc1 into PANDA as part of my thesis. I hope that going from rc1 to the release version wont be a big problem. I jumped right into it (I do question myself if that was the smart way) and I have the conflicts down to cpus.c and softmmu_template.h, and whatever errors the compiler will throw at me when I first build it. There were a few parts that were drastically changed, mostly around the TCG. I'm waiting on the reply from my supervisor about how and when we can publish the source, but I guess I'll know more next week and by then I think I'll also have the merge commit. Sorry, something went wrong. Copy link Member Author
• m000 commented Apr 11, 2020 commented Some thoughts about the (welcome) migration to QEMU 4 codebase. Since PANDA will continue following the development of QEMU, maybe it would be helpful to label PANDA releases based on the underlying QEMU codebase? E.g. current version would be PANDA2 (based on QEMU 2.x) codebase. Next version would be PANDA4 (based on QEMU 4.x). This would make it a bit easier to discuss issues while both versions are in use. I can see this issue growing longer and longer. Maybe a separate branch should be created while stabilizing/working out bugs with the QEMU4-based panda? Then issues related to the branch can be reported individually. A new QEMU4 or PANDA4 label for the issue tracker can be used to filter issues quickly. Finally, it would probably be good to also announce a draft time-plan for the deprecation of the current code-base. This would encourage the community to migrate any incompatible code to the new version. Sorry, something went wrong. Copy link
• glueckself commented Apr 13, 2020 commented I've now uploaded the , however, I'm still fixing compiler errors. I have never merged anything this big before, so I expect there will be some mistakes in there. I would appreciate any feedback. :) I also haven't looked into testing of Qemu and PANDA yet, I think that'll be the next step after getting it to compile. Regarding the checklist: my goal is to get record/replay running (and probably only for i386 and arm). After that, I'll probably have to switch over to my thesis (btw, it's only a BSc thesis). Sorry, something went wrong. Copy link Contributor
• glueckself commented Apr 17, 2020 • edited commented • edited I've got qemu-system-i386 to build, however, some of the "fixes" I made are... a bit ugly (especially ). It manages to boot . And, with a workaround, Linux. But only a . Debian hangs on some udev soft lockups. Issues I've discovered so far: It's very slow. I've tried to look into it, but I couldn't find anything. The main thread has 100% CPU load (might be what causes it to be slow). The cdrom Device timeouts. This causes Linux to fail to boot. Workaround is to start qemu with -nodefaults -vga std (I'm not sure if there is a way to remove only the cdrom drive). Haven't looked into it yet. Soft lock ups in the guest. It crashes when starting with -llvm or on begin_record. The qemu tests/qtest/boot-serial-test hangs. I've marked some places where I don't understand what's going on (or what should be going on) with "//TODO: panda:". I'll try to sort out as many as I can. Also, there are a lot of warnings. I haven't looked into them yet, probably there are bad ones in there. My next goal is to get everything to compile and clean up the warnings and TODOs. I have problems with the C/C++ mixing. Qemu started to use some C specific stuff in (e.g. __builtin_types_compatible_p() in include/qemu/atomic.h ) and g++ doesn't support that. I'm not sure if C-linkages can solve that (i.e. if there is a extern "C" missing somewhere) or if that has to be implemented for C++. Would it be possible for someone to support me there? UPDATE: Now everything builds. However, there is also one more commit of questionable quality. Also, the include dependencies are not set up properly so that the make must be run with -j at least twice to make use of a race condition to create plog.pb.h. Sorry, something went wrong.

• AndrewFasano commented Apr 29, 2020 commented I spent more time than I'd like to admit over the past few days trying to merge qemu 2.10 into PANDA. The merge itself was fairly straightforward and it just took a few hours to handle the conflicts and get it to build. But, unsurprisingly, the built version doesn't actually work. I've spent ~2 days debugging it and I'm still stuck on an error about "Trying to execute code outside RAM or ROM at 0x38000". When I take a trace of instructions executed with -d in_asm, I see about 6k instructions run before the error and they're the same as what qemu 2.10 execute. I think the error must be related to how memory regions are initialized and how the kernel is loaded into memory, but I'm not sure. I was testing x86_64 with a Linux 4.9.99 kernel I built from source: $ ./x86_64-softmmu/panda-system-x86_64 -kernel ./linux-4.9.99/arch/x86_64/boot/bzImage -nographic -append "console=ttyS0" panda-system-x86_64: Trying to execute code outside RAM or ROM at 0x0000000000038000 This usually means one of the following happened: (1) You told QEMU to execute a kernel for the wrong machine type, and it crashed on startup (eg trying to run a raspberry pi kernel on a versatilepb QEMU machine) (2) You didn't give QEMU a kernel or BIOS filename at all, and QEMU executed a ROM full of no-op instructions until it fell off the end (3) Your guest kernel has a bug and crashed by jumping off into nowhere This is almost always one of the first two, so check your command line and that you are using the right type of kernel for this machine. If you think option (3) is likely then you can try debugging your guest with the -d debug options; in particular -d guest_errors will cause the log to include a dump of the guest register state at this point. Execution cannot continue; stopping here. I tried redoing the merge from scratch but ran into the same issue. Code from the second merge (likely the better of the two) is on the branch. Anyone interested in helping me debug? Sorry, something went wrong. Copy link
• glueckself commented Apr 30, 2020 commented I see that you have a commit to disable SMM. Is that a workaround for now to be able to test everything else or do you plan to keep it that way? Please let me know, because if it's the later, then I'll also just disable it and focus on the record/replay issue. Otherwise I'll keep digging. Sorry, something went wrong. Copy link Member Author
• glueckself commented May 1, 2020 • edited commented • edited Vanilla Qemu has a tlb_hit in #4 [...] get_page_addr_code_hostp [...] of the "bad" callstack above, and that's where it takes on a different path. The write to 0x38000 in bios-256k.bin happens in the guest at 0x000ec8a8, btw. I currently have two approaches: In the Seabios source, the enables some . I think one approach is to see if that fails, it may explain why the two address spaces see something different. EDIT: That line is at 0x000ed011 in the guest. The other approach is to find out why the TLB entry received in get_page_addr_code_hostp() is different: panda-5.0: gdb$ p *tlb_entry(env, mmu_idx, addr) {{{addr_read = `*0x38200, addr_write = 0x38200, addr_code = 0x38200, addend = 0xfffffffffffc8000}, dummy = "\000\202\003\000\000\202\003\000\000\202\003\000\000\000\000\000\000\200\374\377\377\377\377\377\340k&\360\377\017\000"}} qemu-5.0: gdb$ p *tlb_entry(env, mmu_idx, addr) {{{addr_read = 0x38000, addr_write = 0x38400, addr_code = 0x38000, addend = 0x7fff89600000}, dummy = "\000\200\003\000\000\204\003\000\000\200\003\000\360\377\017\000\000\000`\211\377\177\000\000\b<\367UUU\000"}} (mmu_idx = 2 and addr = 0x38000 for both cases).

• glueckself commented May 5, 2020 commented SMM is fixed. It's caused by the rr_listener that points to the rr_mem_region_{added,deleted}_cb callbacks in cpu_address_space_init(). The same rr_listener struct is registered multiple times which messes something up. I've workarounded/fixed this by calloc()ing it on the heap for each call: diff --git a/exec.c b/exec.c index 0837fdd840..927e5b9480 100644 --- a/exec.c +++ b/exec.c @@ -851,8 +851,6 @@ CPUState *qemu_get_cpu(int index) #if !defined(CONFIG_USER_ONLY) -MemoryListener rr_listener; - static RR_mem_type rr_mem_region_type(MemoryRegion* mr) { RR_mem_type mtype = RR_MEM_UNKNOWN; if (!(memory_region_is_ram(mr) || memory_region_is_romd(mr))) { @@ -913,10 +911,12 @@ void cpu_address_space_init(CPUState *cpu, int asidx, newas->tcg_as_listener.commit = tcg_commit; memory_listener_register(&newas->tcg_as_listener, as); + //TODO: panda: maybe use something other than calloc? + MemoryListener *rr_listener = calloc(sizeof(MemoryListener), 1); // PANDA Record and Replay - rr_listener.region_add = rr_mem_region_added_cb; - rr_listener.region_del = rr_mem_region_deleted_cb; - memory_listener_register(&rr_listener, as); + rr_listener->region_add = rr_mem_region_added_cb; + rr_listener->region_del = rr_mem_region_deleted_cb; + memory_listener_register(rr_listener, as); } } I'll push it soon. So far, I would say that qemu basics run. But I haven't tried network yet. However, running it with -llvm caused some bugs because the old S2E code in panda/llvm/tcg-llvm.cpp doesn't match the newer Qemu TCG. I've fixed or workarounded some of those, but now I'm back to SMM (see below) and I don't understand the message: LLVM ERROR: Cannot select: 0x7fda00dc8520: i64 = X86ISD::WrapperRIP 0x7fda0192dad0 [ID=8] 0x7fda0192dad0: i64 = TargetGlobalTLSAddress<%struct.rcu_reader_data* @rcu_reader> 0 [TF=10] [ID=6] In function: log_cpu_state_mask Here is the full llvm_ir log: It happens on the rsm instruction (the instruction to leave SMM). If I disable SMM (-machine smm=off) another error occurs (ERROR: unknown TCG micro operation 'extract2_i32') but I think I can handle that one. 🎉 3 Sorry, something went wrong. Copy link
• janbbeck commented Aug 14, 2020 commented Just a quick question for the people that want a newer QEMU. Are there specific features from QEMU 4+ that are needed? Has anyone considered that back porting new architectures/boards to PANDA might actually be easier than upgrading PANDA itself? Upgrading the QEMU baseline should be possible, but it will involve dropping commits or using the old version anyway, particularly around the CPU loop. I think that is a very good question to ask before embarking on a process such as this..... Can anyone think of some nice-to have feature that qemu introduced in later versions? That would probably also point to a different version to strive for. For example if useful feature A was introduced in qemu x.y.z, then that may be a more reasonable target than qemu 4+ Sorry, something went wrong. mentioned this issue Open changed the title Update to Qemu 4!
