into staging ppc patch queue 2018-07-03 Here's a last minue pull request before today's soft freeze. Ideally I would have sent this earlier, but I was waiting for a couple of extra fixes I knew were close. And the freeze crept up on me, like always. Most of the changes here are bugfixes in any case. There are some cleanups as well, which have been in my staging tree for a little while. There are a couple of truly new features (some extensions to the sam460ex platform), but these are low risk, since they only affect a new and not really stabilized machine type anyway.

2018-07-03vga: disable global_vmstate for 3.0+ machine typesGerd Hoffmann
Move global_vmstate from vga_common_init() parameter to VGACommonState field. Set global_vmstate to true for isa vga devices, so nothing changes here. virtio-vga and secondary-vga already set global_vmstate to false so no change here either. All other pci vga devices get a new global-vmstate property, defaulting to false. A compat property flips it to true for older machine types. With this in place you don't get a vmstate section naming conflict any more when adding multiple pci vga devices to your vm.

2018-07-02s390x/tcg: properly implement the TODDavid Hildenbrand
Right now, each CPU has its own TOD. Especially, the TOD will differ based on creation time of a CPU - e.g. when hotplugging a CPU the times will differ quite a lot, resulting in stall warnings in the guest. Let's use a single TOD by implementing our new TOD device. Prepare it for TOD-clock epoch extension. Most importantly, whenever we set the TOD, we have to update the CKC timer. Introduce "tcg_s390x.h" just like "kvm_s390x.h" for tcg specific function declarations that should not go into cpu.h.

2018-07-02loader: Check access size when calling rom_ptr() to avoid crashesThomas Huth
The rom_ptr() function allows direct access to the ROM blobs that we load during startup. However, there are currently no checks for the size of the accesses, so it's currently possible to crash QEMU for example with: $ echo "Insane in the mainframe" > /tmp/test.txt $ s390x-softmmu/qemu-system-s390x -kernel /tmp/test.txt -append xyz Segmentation fault (core dumped) $ s390x-softmmu/qemu-system-s390x -kernel /tmp/test.txt -initrd /tmp/test.txt Segmentation fault (core dumped) $ echo -n HdrS > /tmp/hdr.txt $ sparc64-softmmu/qemu-system-sparc64 -kernel /tmp/hdr.txt -initrd /tmp/hdr.txt Segmentation fault (core dumped) We need a possibility to check the size of the ROM area that we want to access, thus let's add a size parameter to the rom_ptr() function to avoid these problems.

2018-06-29hw/scsi: add VPD Block Limits emulationDaniel Henrique Barboza
The VPD Block Limits Inquiry page is optional, allowing SCSI devices to not implement it. This is the case for devices like the MegaRAID SAS 9361-8i and Microsemi PM8069. In case of SCSI passthrough, the response of this request is used by the QEMU SCSI layer to set the max_io_sectors that the guest device will support, based on the value of the max_sectors_kb that the device has set in the host at that time. Without this response, the guest kernel is free to assume any value of max_io_sectors for the SCSI device. If this value is greater than the value from the host, SCSI Sense errors will occur because the guest will send read/write requests that are larger than the underlying host device is configured to support. An example of this behavior can be seen in [1]. A workaround is to set the max_sectors_kb host value back in the guest kernel (a process that can be automated using rc.local startup scripts and the like), but this has several drawbacks: - it can be troublesome if the guest has many passthrough devices that needs this tuning; - if a change in max_sectors_kb is made in the host side, manual change in the guests will also be required; - during an OS install it is difficult, and sometimes not possible, to go to a terminal and change the max_sectors_kb prior to the installation. This means that the disk can't be used during the install process. The easiest alternative here is to roll back to scsi-hd, install the guest and then go back to SCSI passthrough when the installation is done and max_sectors_kb can be set. An easier way would be to QEMU handle the absence of the Block Limits VPD device response, setting max_io_sectors accordingly and allowing the guest to use the device without the hassle. This patch adds emulation of the Block Limits VPD response for SCSI passthrough devices of type TYPE_DISK that doesn't support it. The following changes were made: - scsi_handle_inquiry_reply will now check the available VPD pages from the Inquiry EVPD reply. In case the device does not - a new function called scsi_generic_set_vpd_bl_emulation, that is called during device realize, was created to set a new flag 'needs_vpd_bl_emulation' of the device. This function retrieves the Inquiry EVPD response of the device to check for VPD BL support. - scsi_handle_inquiry_reply will now check the available VPD pages from the Inquiry EVPD reply in case the device needs VPD BL emulation, adding the Block Limits page (0xb0) to the list. This will make the guest kernel aware of the support that we're now providing by emulation. - a new function scsi_emulate_block_limits creates the emulated Block Limits response. This function is called inside scsi_read_complete in case the device requires Block Limits VPD emulation and we detected a SCSI Sense error in the VPD Block Limits reply that was issued from the guest kernel to the device. This error is expected: we're reporting support from our side, but the device isn't aware of it. With this patch, the guest now queries the Block Limits page during the device configuration because it is being advertised in the Supported Pages response. It will either receive the Block Limits page from the hardware, if it supports it, or will receive an emulated response from QEMU. At any rate, the guest now has the information to set the max_sectors_kb parameter accordingly, sparing the user of SCSI sense errors that would happen without the emulated response and in the absence of Block Limits support from the hardware.

2018-06-29hw/scsi: centralize SG_IO calls into single functionDaniel Henrique Barboza
For the VPD Block Limits emulation with SCSI passthrough, we'll issue an Inquiry request with EVPD set to retrieve the available VPD pages of the device. This would be done in a way similar of what scsi_generic_read_device_identification does: create a SCSI command and a reply buffer, fill in the sg_io_hdr_t structure, call blk_ioctl, check if an error occurred, process the response. This same process is done in other 2 functions, get_device_type and get_stream_blocksize. They differ in the command/reply buffer and post-processing, everything else is almost a copy/paste. Instead of adding a forth copy/pasted-ish code when adding the passthrough VPD BL emulation, this patch extirpates this repetition of those 3 functions and put it into a new one called scsi_SG_IO_FROM_DEV. Any future code that wants to execute an SG_DXFER_FROM_DEV to the device can use it, avoiding filling sg_io_hdr_t again and et cetera.

2018-06-29hw/scsi: cleanups before VPD BL emulationDaniel Henrique Barboza
To add support for the emulation of Block Limits VPD page for passthrough devices, a few adjustments in the current code base is required to avoid repetition and improve clarity. In scsi-generic.c, detach the Inquiry handling from scsi_read_complete and put it into a new function called scsi_handle_inquiry_reply. This change aims to avoid cluttering of scsi_read_complete when we more logic in the Inquiry response handling is added in the next patches, centralizing the changes in the new function. In scsi-disk.c, take the build of all emulated VPD pages from scsi_disk_emulate_inquiry and make it available to other files into a non-static function called scsi_disk_emulate_vpd_page. Making it public will allow the future VPD BL emulation code for passthrough devices to use it from scsi-generic.c, avoiding copy/pasting this code solely for that purpose. It also has the advantage of providing emulation of all VPD pages in case we need to emulate other pages in other scenarios. As a bonus, scsi_disk_emulate_inquiry got tidier.

For a PCDIMM, both functions are to return the same thing, so share the implementation. All current users are called after the device has been realized, so we can expect the calls to succeed.

2018-06-26aspeed/timer: use the APB frequency from the SCUCédric Le Goater
The timer controller can be driven by either an external 1MHz clock or by the APB clock. Today, the model makes the assumption that the APB frequency is always set to 24MHz but this is incorrect. The AST2400 SoC on the palmetto machines uses a 48MHz input clock source and the APB can be set to 48MHz. The consequence is a general system slowdown. The QEMU machines using the AST2500 SoC do not seem impacted today because the APB frequency is still set to 24MHz. We fix the timer frequency for all SoCs by linking the Timer model to the SCU model. The APB frequency driving the timers is now the one configured for the SoC.

2018-06-26aspeed/scu: introduce clock frequenciesCédric Le Goater
All Aspeed SoC clocks are driven by an input source clock which can have different frequencies : 24MHz or 25MHz, and also, on the Aspeed AST2400 SoC, 48MHz. The H-PLL (CPU) clock is defined from a calculation using parameters in the H-PLL Parameter register or from a predefined set of frequencies if the setting is strapped by hardware (Aspeed AST2400 SoC). The other clocks of the SoC are then defined from the H-PLL using dividers. We introduce first the APB clock because it should be used to drive the Aspeed timer model.
