2015-12-02translate-all: ensure host page mask is always extended with 1'sPaolo Bonzini1-2/+1
Anthony reported that >4GB guests on Xen with 32bit QEMU broke after commit 4ed023c ("Round up RAMBlock sizes to host page sizes", 2015-11-05). In that patch sizes are masked against qemu_host_page_size/mask which are uintptr_t, and thus 32bit on a 32bit QEMU, even though the ram space might be bigger than 4GB on Xen. Since ram_addr_t is not available on user-mode emulation targets, ensure that we get a sign extension when masking away the low bits of the address. Remove the ~10 year old scary comment that the type of these variables is probably wrong, with another equally scary comment. The new comment however does not have "???" in it, which is arguably an improvement. For completeness use the alignment macros in linux-user and bsd-user instead of manually doing an &. linux-user and bsd-user are not affected by the Xen issue, however.

All tcg host architectures now support the guest base and as there is no real performance lost, it can be always enabled. Anyway, guest base use can be disabled lively by setting guest base to 0. CONFIG_USE_GUEST_BASE is defined as (USE_GUEST_BASE && USER_ONLY), it should have to be replaced by CONFIG_USER_ONLY in non CONFIG_USER_ONLY parts, but as some other parts are using !CONFIG_SOFTMMU I have chosen to use !CONFIG_SOFTMMU instead.

2014-06-11bsd-user/mmap.c: Don't try to override g_malloc/g_freePeter Maydell1-60/+0
Trying to override the implementations of g_malloc and g_free is a really bad idea -- it means statically linked builds fail to link (because of the multiple definitions provided by this file and by glib), and non-statically linked builds segfault as soon as they try to do anything more complicated than printing the usage message. Remove these overridden versions and just use the glib ones. This is sufficient that bsd-user can run basic x86-64 binaries on OpenBSD again; FreeBSD and NetBSD seem to have further issues.

2014-06-02Revert "bsd-user: replace fprintf(stderr, ...) with error_report()"Peter Maydell3-9/+9
This reverts commit 1fba509527beb74bdcf50bc07ad3cd8244ad9c61. That commit converted various fprintf(stderr, ...) calls to use error_report(); however none of these bsd-user files include a header which gives a prototype for error_report, so this causes compiler warnings. Since these are just straightforward reporting of command line errors, we should handle these in the obvious way by printing to stderr, as we do for linux-user. There's no need to drag in the error-handling framework for this, especially since user-mode doesn't have the "maybe we need to send this to the monitor" issues system emulation does.

2013-02-26qemu-log: default to stderr for logging outputPeter Maydell1-10/+8
Switch the default for qemu_log logging output from "/tmp/qemu.log" to stderr. This is an incompatible change in some sense, but logging is mostly used for debugging purposes so it shouldn't affect production use. The previous behaviour can be obtained by adding "-D /tmp/qemu.log" to the command line. This change requires us to: * update all the documentation/help text (we take the opportunity to smooth out minor inconsistencies between the phrasing in linux-user/bsd-user/system help messages) * make linux-user and bsd-user defer to qemu-log for the default logging destination rather than overriding it themselves * ensure that all logfile closing is done via qemu_log_close() and that that function doesn't close stderr as well as the obvious change to the behaviour of do_qemu_set_log() when no logfile name has been specified.

2013-02-16qemu-log: Rename the public-facing cpu_set_log function to qemu_set_logPeter Maydell1-1/+1
Rename the public-facing function cpu_set_log to qemu_set_log. This requires us to rename the internal-only qemu_set_log() to do_qemu_set_log(). Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2013-02-16qemu-log: Rename cpu_str_to_log_mask to qemu_str_to_log_maskPeter Maydell1-1/+1
Rename cpu_str_to_log_mask() to qemu_str_to_log_mask(), since the qemu_log functionality is no longer restricted to TCG CPU debug logging. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2013-02-16qemu-log: Abstract out "print usage message about valid log categories"Peter Maydell1-5/+1
Abstract out the "print a human readable list of all the valid log categories" functionality which is currently duplicated in three separate places. (We leave the monitor.c help_cmd() implementation as-is since it wants to send the message to the monitor and add its own information.)

2013-02-16qemu-log: Unify {cpu_set,set_cpu}_log_filename as qemu_set_log_filenamePeter Maydell1-1/+1
The qemu_log() functionality is no longer specific to TCG CPU debug logs. Rename cpu_set_log_filename() to qemu_set_log_filename() and drop the pointless wrapper set_cpu_log_filename().

2013-02-01linux-user: bsd-user: Don't reset X86CPU twiceAndreas Färber1-1/+1
Since commit 65dee38052597b6285eb208125369f01b29ba6c1 (target-i386: move cpu_reset and reset callback to cpu.c) the x86 CPU is reset through cpu_init() but was still reset immediately after in linux-user and bsd-user. Clean this up. Similarly in linux-user/syscall.c it is also reset after cpu_copy(). But that's a bug of its own, fixing which poses a semantic change.
