2012-07-14targphys.h: Define TARGET_PRI*PHYS format specifier macrosPeter Maydell1-0/+16
Define a set of TARGET_PRI*PHYS format specifier macros for working with target_phys_addr_t types. These follow the standard pattern for such macros, and are more flexible than TARGET_FMT_plx, which does not allow specification of field widths.

2012-07-14disas: Fix printing of addresses in disassemblyPeter Maydell1-0/+19
In our disassembly code, the bfd_vma type is always 64 bits, even if the target's virtual address width is only 32 bits. This means that when we print out addresses we need to truncate them to 32 bits, to avoid odd output which has incorrectly sign-extended a value to 64 bits, for instance this ARM example: 0x80479a60: e59f4088 ldr r4, [pc, #136] ; 0xffffffff80479a4f (It would also be possible to truncate before passing the address to info->print_address_func(), but truncating in the final print function is the same approach that binutils takes to this problem.)

2012-07-12target-arm: Implement long-descriptor PAR formatPeter Maydell1-10/+69
Implement the different format of the PAR when long descriptor translation tables are in use. Note that we assume that get_phys_addr() returns a long-descriptor format DFSR value on failure if long descriptors are in use; this added subtlety tips the balance and makes it worth adding a comment documenting the API to get_phys_addr().

2012-07-12target-arm: Add 64 bit PAR, TTBR0, TTBR1 for LPAEPeter Maydell3-3/+87
Under LPAE, the cp15 registers PAR, TTBR0 and TTBR1 are extended to 64 bits, with a 64 bit (MRRC/MCRR) access path to read the full width of the register. Add the state fields for the top half and the 64 bit access path. Actual use of the top half of the register will come with the addition of the long-descriptor translation table format support. For the PAR we also need to correct the masking applied for 32 bit writes (there are no bits reserved if LPAE is implemented) and clear the high half when doing a 32 bit result VA-to-PA lookup.

Implement the privileged-execute-never (PXN) translation table bit. It is implementation-defined whether this is implemented, so we give it its own ARM_FEATURE_ flag.

2012-07-12ARM: Make target_phys_addr_t 64 bits and physaddrs 40 bitsPeter Maydell2-2/+2
Make target_phys_addr_t 64 bits for ARM targets, and set TARGET_PHYS_ADDR_SPACE_BITS to 40. This should have no effect for ARM boards where physical addresses really are 32 bits (except perhaps a slight performance hit on 32 bit hosts for system emulation) but allows us to implement the Large Physical Address Extensions for Cortex-A15, which mean 40 bit physical addresses.

Fix errors in the TCG temp handling in the 64 bit coprocessor write path: we were reusing a 32 bit temp after it had been freed by store_reg(), and failing to free a 64 bit temp. This bug has no visible effect at this point because there aren't any non-NOP 64 bit registers yet; it needs to be fixed as a prerequisite for the 64 bit registers in LPAE support.

2012-07-11qemu_find_file: check name as a straight path even if it has no '/'Peter Maydell1-3/+2
Make qemu_find_file() check for the passed in name as a straight pathname even if it doesn't have any path separator character in it. This means that "-bios foo", "-dtb foo" etc will find a file 'foo' in the current directory. This removes an inconsistency with -kernel and -initrd, which both accept plain filenames as meaning files in the current directory. It's also less confusing for the user than an undocumented restriction that "this option accepts a filename, except for the special case where the filename you pass happens not to have a '/' in it, in which case we'll ignore it."

2012-07-10s390: autodetect map privateChristian Borntraeger5-15/+56
By default qemu will use MAP_PRIVATE for guest pages. This will write protect pages and thus break on s390 systems that dont support this feature. Therefore qemu has a hack to always use MAP_SHARED for s390. But MAP_SHARED has other problems (no dirty pages tracking, a lot more swap overhead etc.) Newer systems allow the distinction via KVM_CAP_S390_COW. With this feature qemu can use the standard qemu alloc if available, otherwise it will use the old s390 hack.

2012-07-09slirp: Ensure smbd and shared directory exist when enable smbDunrong Huang1-0/+12
Users may pass the following parameters to qemu: $ qemu-kvm -net nic -net user,smb= ... $ qemu-kvm -net nic -net user,smb ... $ qemu-kvm -net nic -net user,smb=bad_directory ... In these cases, qemu started successfully while samba server failed to start. Users will confuse since samba server failed silently without any indication of what it did wrong. To avoid it, we check whether the shared directory exist and if users have permission to access this directory when QEMU's "built-in" SMB server is enabled.

2012-07-09slirp: add 'cmd:' target for guestfwdAlexander Graf2-18/+48
When using guestfwd=, Qemu only connects the virtual server's TCP port to a single chardev. This is useless in most cases, as we usually want to have more than a single connection from the guest to the outside world. This patch adds a new cmd: target to guestfwd= that allows for execution of a command on every TCP connection. This leverages the same code as the -smb parameter, just that here the command is user defined.

Harmless, because: * The only way to set a geometry hint is -drive if=none,cyls=... Since commit c219331e, probably unintentional. * The only use of drv->drive is as argument to another bdrv_get_floppy_geometry_hint(). Which doesn't use it, since the geometry hint is still there.
