2021-02-11target/arm: Don't migrate CPUARMState.featuresAaron Lindsay1-1/+1
As feature flags are added or removed, the meanings of bits in the `features` field can change between QEMU versions, causing migration failures. Additionally, migrating the field is not useful because it is a constant function of the CPU being used.

2021-02-10docs: fix Parallels Image "dirty bitmap" sectionDenis V. Lunev1-1/+1
Original specification says that l1 table size if 64 * l1_size, which is obviously wrong. The size of the l1 entry is 64 _bits_, not bytes. Thus 64 is to be replaces with 8 as specification says about bytes. There is also minor tweak, field name is renamed from l1 to l1_table, which matches with the later text. Signed-off-by: Denis V.

Since we don't model cache in QEMU, let's add a write helper to emulate the cache operations completing instantly.

2021-02-10hw/net: fsl_etsec: Reverse the RCTRL.RSF logicBin Meng1-1/+1
Per MPC8548ERM [1] chapter 14.5.3.4.1: When RCTRL.RSF is 1, frames less than 64 bytes are accepted upon a DA match. But currently QEMU does the opposite. This commit reverses the RCTRL.RSF testing logic to match the manual. Due to the reverse of the logic, certain guests may potentially break if they don't program eTSEC to have RCTRL.RSF bit set. When RCTRL.RSF is 0, short frames are silently dropped, however as of today both slirp and tap networking do not pad short frames (e.g.: an ARP packet) to the minimum frame size of 60 bytes. So ARP requests will be dropped, preventing the guest from becoming visible on the network. The same issue was reported on e1000 and vmxenet3 before, see: commit 78aeb23eded2 ("e1000: Pad short frames to minimum size (60 bytes)") commit 40a87c6c9b11 ("vmxnet3: Pad short frames to minimum size (60 bytes)") [1] https://www.nxp.com/docs/en/reference-manual/MPC8548ERM.pdf Fixes: eb1e7c3e5146 ("Add Enhanced Three-Speed Ethernet Controller (eTSEC)") Signed-off-by: Bin Meng <bin.meng@windriver.com> Message-Id: <1612923021-19746-1-git-send-email-bmeng.cn@gmail.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2021-02-10spapr_numa.c: fix ibm,max-associativity-domains calculationDaniel Henrique Barboza1-1/+3
The current logic for calculating 'maxdomain' making it a sum of numa_state->num_nodes with spapr->gpu_numa_id. spapr->gpu_numa_id is used as a index to determine the next available NUMA id that a given NVGPU can use. The problem is that the initial value of gpu_numa_id, for any topology that has more than one NUMA node, is equal to numa_state->num_nodes. This means that our maxdomain will always be, at least, twice the amount of existing NUMA nodes. This means that a guest with 4 NUMA nodes will end up with the following max-associativity-domains: rtas/ibm,max-associativity-domains 00000004 00000008 00000008 00000008 00000008 This overtuning of maxdomains doesn't go unnoticed in the guest, being detected in SLUB during boot: dmesg | grep SLUB [ 0.000000] SLUB: HWalign=128, Order=0-3, MinObjects=0, CPUs=4, Nodes=8 SLUB is detecting 8 total nodes, with 4 nodes being online. This patch fixes ibm,max-associativity-domains by considering the amount of NVGPUs NUMA nodes presented in the guest, instead of just spapr->gpu_numa_id.

2021-02-10ppc/pnv: Remove default disablement of the PNOR contentsCédric Le Goater1-8/+0
On PowerNV systems, the BMC is in charge of mapping the PNOR contents on the LPC FW address space using the HIOMAP protocol. Under QEMU, we emulate this behavior and we also add an extra control on the flash accesses by letting the HIOMAP command handler decide whether the memory region is accessible or not depending on the firmware requests. However, this behavior is not compatible with hostboot like firmwares which need this mapping to be always available. For this reason, the PNOR memory region is initially disabled for skiboot mode only. This is badly placed under the LPC model and requires the use of the machine. Since it doesn't add much, simply remove the initial setting. The extra control in the HIOMAP command handler will still be performed.

The PowerNV machine can be run with an external IPMI BMC device connected to a remote QEMU machine acting as BMC, using these options : -chardev socket,id=ipmi0,host=localhost,port=9002,reconnect=10 \ -device ipmi-bmc-extern,id=bmc0,chardev=ipmi0 \ -device isa-ipmi-bt,bmc=bmc0,irq=10 \ -nodefaults In that case, some aspects of the BMC initialization should be skipped, since they rely on the simulator interface.

2021-02-10spapr.c: add 'name' property for hotplugged CPUs nodesDaniel Henrique Barboza1-0/+13
In the CPU hotunplug bug [1] the guest kernel throws a scary message in dmesg: pseries-hotplug-cpu: Failed to offline CPU <NULL>, rc: -16 The reason isn't related to the bug though. This happens because the kernel file arch/powerpc/platform/pseries/hotplug-cpu.c, function dlpar_cpu_remove(), is not finding the device_node.name of the offending CPU. We're not populating the 'name' property for hotplugged CPUs. Since the kernel relies on device_node.name for identifying CPU nodes, and the CPUs that are coldplugged has the 'name' property filled by SLOF, this is creating an unneeded inconsistency between hotplug and coldplug CPUs in the kernel. Let's fill the 'name' property for hotplugged CPUs as well. This will make the guest dmesg throws a less intimidating message when we try to unplug the last online CPU: pseries-hotplug-cpu: Failed to offline CPU PowerPC,POWER9@1, rc: -16 [1] https://bugzilla.redhat.com/1911414 Signed-off-by: Daniel Henrique Barboza <danielhb413@gmail.com> Message-Id: <20210120232305.241521-3-danielhb413@gmail.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
