2018-06-26target/arm: Handle small regions in get_phys_addr_pmsav8()Peter Maydell
Allow ARMv8M to handle small MPU and SAU region sizes, by making get_phys_add_pmsav8() set the page size to the 1 if the MPU or SAU region covers less than a TARGET_PAGE_SIZE. We choose to use a size of 1 because it makes no difference to the core code, and avoids having to track both the base and limit for SAU and MPU and then convert into an artificially restricted "page size" that the core code will then ignore. Since the core TCG code can't handle execution from small MPU regions, we strip the exec permission from them so that any execution attempts will cause an MPU exception, rather than allowing it to end up with a cpu_abort() in get_page_addr_code(). (The previous code's intention was to make any small page be treated as having no permissions, but unfortunately errors in the implementation meant that it didn't behave that way. It's possible that some binaries using small regions were accidentally working with our old behaviour and won't now.) We also retain an existing bug, where we ignored the possibility that the SAU region might not cover the entire page, in the case of executable regions. This is necessary because some currently-working guest code images rely on being able to execute from addresses which are covered by a page-sized MPU region but a smaller SAU region. We can remove this workaround if we ever support execution from small regions.

2018-06-26target/arm: Set page (region) size in get_phys_addr_pmsav7()Peter Maydell
We want to handle small MPU region sizes for ARMv7M. To do this, make get_phys_addr_pmsav7() set the page size to the region size if it is less that TARGET_PAGE_SIZE, rather than working only in TARGET_PAGE_SIZE chunks. Since the core TCG code con't handle execution from small MPU regions, we strip the exec permission from them so that any execution attempts will cause an MPU exception, rather than allowing it to end up with a cpu_abort() in get_page_addr_code().

2018-06-26tcg: Support MMU protection regions smaller than TARGET_PAGE_SIZEPeter Maydell
Add support for MMU protection regions that are smaller than TARGET_PAGE_SIZE. We do this by marking the TLB entry for those pages with a flag TLB_RECHECK. This flag causes us to always take the slow-path for accesses. In the slow path we can then special case them to always call tlb_fill() again, so we have the correct information for the exact address being accessed. This change allows us to handle reading and writing from small regions; we cannot deal with execution from the small region.

2018-06-25ahci: fix FIS I bit and PIO Setup FIS interruptPaolo Bonzini
The "I" bit in PIO Setup and D2H FISes is exclusively a device concept and the irqstatus register in the controller does not matter. The SATA spec says when it should be one; for D2H FISes in practice it is always set, while the PIO Setup FIS has several subcases that are documented in the patch. Also, the PIO Setup FIS interrupt is actually generated _after_ data has been received. Someone should probably spend some time reading the SATA specification and figuring out the more obscure fields in the PIO Setup FIS, but this is enough to fix SeaBIOS booting from ATAPI CD-ROMs over an AHCI controller.

2018-06-25vl.c: do not allow --daemonize in combination with --preconfig CLI optionIgor Mammedov
some users when using --daemonize expect that QEMU will parse CLI options, initialize VM and only then complete daemonzation by signalling lead process to exit and start listening on monitor socket. So users treat parent process exit as sync point to connect to QEMU's monitor. That however doesn't work when --preconfig options is used, since it provides monitor before completing daemonization and expects user to issue exit-preconfig command when additional configuration via monitor is finished. We also can't move completing daemonization before preconfig monitor becomes available, since that would imply: * partially loosing ability to configure QEMU instance in --preconfig mode since QEMU might drop privileges, chroot and do other things when daemonization is completed * lead to loss of error messages in case they would happen after daemonization Be proactive now and make options mutually exclusive, so users would get clear error message instead of waiting for lead process exit indefinitely before connecting to monitor. PS: In case someone would come up with usecase where both options should be enabled at the same time we could drop this restriction as far as daemonization point is left where it is now (os_setup_post).

2018-06-25audio/hda: create millisecond timers that handle IOGerd Hoffmann
Currently, the HDA device tries to sync itself with the QEMU audio backend by waiting for the guest driver to handle buffer completion interrupts. This causes the backend to often read too much data from the device, as well as running out of data whenever the guest takes too long to handle the interrupt. According to the HDA specification, the guest is also not required to use interrupts, but can also sync itself by polling the LPIB registers. This patch will introduce high frequency (1000Hz) timers that interface with the device and allow for much smoother emulation of the LPIB registers. Since the timing is now provided by these timers, the need to wait for buffer completion interrupts also ceases.

2018-06-22i386: Remove generic SMT thread checkBabu Moger
Remove generic non-intel check while validating hyperthreading support. Certain AMD CPUs can support hyperthreading now. CPU family with TOPOEXT feature can support hyperthreading now.

Enable TOPOEXT feature on EPYC CPU. This is required to support hyperthreading on VM guests. Also extend xlevel to 0x8000001E. Disable topoext on PC_COMPAT_2_12 and keep xlevel 0x8000000a.

2018-06-22i386: Fix up the Node id for CPUID_8000_001EBabu Moger
This is part of topoext support. To keep the compatibility, it is better we support all the combination of nr_cores and nr_threads currently supported. By allowing more nr_cores and nr_threads, we might end up with more nodes than we can actually support with the real hardware. We need to fix up the node id to make this work. We can achieve this by shifting the socket_id bits left to address more nodes.

2018-06-22i386: Define AMD's no SSB mitigation needed.Konrad Rzeszutek Wilk
AMD future CPUs expose a mechanism to tell the guest that the Speculative Store Bypass Disable is not needed and that the CPU is all good. This is exposed via the CPUID 8000_0008.EBX[26] bit.
