2011-12-06configure: Print a banner comment at the top of config.logPeter Maydell
Print a banner comment at the top of config.log identifying when configure was run and the arguments used. This is occasionally useful for debugging purposes. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2011-12-06configure: Include #define name in check_define compiler errorPeter Maydell
Include the name of the #define being tested for in the compiler error produced when a check_define test is run and fails. This appears only in the config.log, but it does make it a little easier to debug problems by inspecting config.log.

2011-12-05configure: Drop armv4l/armv4b distinction in $cpuPeter Maydell
Drop the distinction between armv4l/armv4b in the $cpu variable (ie host cpu type) in favour of calling everything 'arm'. This makes it the same as the ARCH setting and removes some special casing. The only thing we were using the distinction for was to decide which endianness to use in cross compilation; do a cpp define check there instead.

2011-11-28configure: avoid screening of --{en, dis}able-usb-redir optionsMax Filippov
--*dir) option pattern precede --{en,dis}able-usb-redir) patterns in the option analysis switch, making the latter options have no effect. There were some --*dir that are supported by Autoconf and not by QEMU configure. The aim was to let QEMU packagers use the rpm (or similar) macro that overrides directories for their distribution. Replace --*dir with exact option names. Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-11-21configure: build position independent executables on x86-Linux hostsAvi Kivity
Change the default on x86 Linux hosts to building PIE (position independent executables); instead of restricting the option to user-only targets, apply it to all targets. In addition, set the relocation sections to read-only (relro) when available; this reduces the attack surface by disallowing changes to relocation tables at runtime. While PIE reduces performance and relro increases load time, it greatly improves security, with the potential to reduce a code execution vulnerability to a self denial of service. Non-x86 are not changed, as they require TCG changes; neither are non-Linux, due to lack of test coverage.

2011-10-30PPC: Fail configure when libfdt is not availableAlexander Graf
We have several targets in the PPC tree now that basically require libfdt to function properly, namely the pseries and the e500 targets. This dependency will rather increase than decrease in the future, so I want to make sure that people building shiny new 1.0 actually have libfdt installed to get rid of a few ifdefs in the code. Warning: This patch will likely make configure fail for people who don't select their own --target-list, but don't have libfdt development packages installed. However, we really need this new dependency to move on. Signed-off-by: Alexander Graf <agraf@suse.de> --- v1 -> v2: - no paranthesis - no fdt check for config_pseries - add . in error message

2011-10-28iSCSI block driverRonnie Sahlberg
This provides built-in support for iSCSI to QEMU. This has the advantage that the iSCSI devices need not be made visible to the host, which is useful if you have very many virtual machines and very many iscsi devices. It also has the benefit that non-root users of QEMU can access iSCSI devices across the network without requiring root privilege on the host. This driver interfaces with the multiplatform posix library for iscsi initiator/client access to iscsi devices hosted at git://github.com/sahlberg/libiscsi.git The patch adds the driver to interface with the iscsi library. It also updated the configure script to * by default, probe is libiscsi is available and if so, build qemu against libiscsi. * --enable-libiscsi Force a build against libiscsi. If libiscsi is not available the build will fail. * --disable-libiscsi Do not link against libiscsi, even if it is available. When linked with libiscsi, qemu gains support to access iscsi resources such as disks and cdrom directly, without having to make the devices visible to the host. You can specify devices using a iscsi url of the form : iscsi://[<username>[:<password>@]]<host>[:<port]/<target-iqn-name>/<lun> When using authentication, the password can optionally be set with LIBISCSI_CHAP_PASSWORD="password" to avoid it showing up in the process list Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2011-09-09configure: Avoid duplicate flags when calling compile_progStefan Weil
This patch removes redundant shell code and cleans it a little bit. Shell macro compile_prog takes two arguments: local_cflags and local ldflags. $QEMU_CFLAGS is added automatically to the cflags, so there is no need to pass it as an argument. It is also unnecessary to pass -Werror twice. $flag is a compiler warning option, so it should be in local_cflags instead of local_ldflags.

2011-09-02main: force enabling of I/O threadAnthony Liguori
Enabling the I/O thread by default seems like an important part of declaring 1.0. Besides allowing true SMP support with KVM, the I/O thread means that the TCG VCPU doesn't have to multiplex itself with the I/O dispatch routines which currently requires a (racey) signal based alarm system. I know there have been concerns about performance. I think so far the ones that have come up (virtio-net) are most likely due to secondary reasons like decreased batching. I think we ought to force enabling I/O thread early in 1.0 development and commit to resolving any lingering issues. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
