2014-06-05target-i386: set correct error code for reserved bit accessPaolo Bonzini
The correct error code is 9 (present, reserved), not 8. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-06-05target-i386: introduce support for 1 GB pagesPaolo Bonzini
Given the simplifications to the code in the previous patches, this is now very simple to do. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

This will help adding 1GB page support in the next patch. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-06-05target-i386: tweak handling of PG_NX_MASKPaolo Bonzini
Remove the tail of the PAE case, so that we can use "goto" in the next patch to jump to the protection checks. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2014-06-05target-i386: fix coding standards in x86_cpu_handle_mmu_faultPaolo Bonzini
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-06-05target-i386: simplify SMAP handling in MMU_KSMAP_IDXPaolo Bonzini
Do not use this MMU index at all if CR4.SMAP is false, and drop the SMAP check from x86_cpu_handle_mmu_fault. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-06-05target-i386: fix kernel accesses with SMAP and CPL = 3Paolo Bonzini
With SMAP, implicit kernel accesses from user mode always behave as if AC=0. To do this, kernel mode is not anymore a separate MMU mode. Instead, KERNEL_IDX is renamed to KSMAP_IDX and the kernel mode accessors wrap KSMAP_IDX and KNOSMAP_IDX. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-06-05target-i386: move check_io helpers to seg_helper.cPaolo Bonzini
Prepare for adding _kernel accessors there in the next patch. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-06-05target-i386: rename KSMAP to KNOSMAPPaolo Bonzini
This is the mode where SMAP is overridden, put "NO" in its name. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-06-05softmmu: move all load/store functions to cpu_ldst.hPaolo Bonzini
Unify pieces of cpu-all.h, exec-all.h, softmmu_exec.h and tcg/tcg.h into a single new header file with all helpers. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-06-05softmmu: introduce cpu_ldst.hPaolo Bonzini
This will collect all load and store helpers soon. For now it is just a replacement for softmmu_exec.h, which this patch stops including directly, but we also include it where this will be necessary in order to simplify the next patch. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-06-05target-arm: move arm_*_code to a separate filePaolo Bonzini
These will soon require cpu_ldst.h, so move them out of cpu.h. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-06-05softmmu: move softmmu_template.h out of include/Paolo Bonzini
It is only included in cputlb.c now. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-06-05softmmu: commonize helper definitionsPaolo Bonzini
They do not need to be in op_helper.c. Because cputlb.c now includes softmmu_template.h twice for each size, io_readX must be elided the second time through. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-06-05softmmu: move ALIGNED_ONLY to cpu.hPaolo Bonzini

2014-06-05softmmu: make do_unaligned_access a method of CPUPaolo Bonzini
We will reference it from more files in the next patch. To avoid ruining the small steps we're making towards multi-target, make it a method of CPU rather than just a global. Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-06-05softmmu: move definition of CPU_MMU_INDEX to inclusion site, drop ACCESS_TYPEPaolo Bonzini

2014-06-05softmmu: start introducing SOFTMMU_CODE_ACCESS in softmmu_header.hPaolo Bonzini
This preprocessor symbol is already used in softmmu_template.h. We will use it to distinguish the two "fake" ACCESS_TYPEs NB_MMU_MODES and NB_MMU_MODES + 1. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-06-05hw: use ld_p/st_p instead of ld_raw/st_rawPaolo Bonzini
The ld_raw and st_raw definitions are only needed in code that must compile for both user-mode and softmmu emulation. Device models can use the equivalent ld_p/st_p which are simple pointer accessors. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2014-06-05cputlb: Fix regression with TCG interpreter (bug 1310324)Stefan Weil
Commit 0f842f8a246f2b5b51a11c13f933bf7a90ae8e96 replaced GETPC_EXT() which was derived from GETPC() by GETRA_EXT() without fixing cputlb.c. A later patch replaced GETRA_EXT() by GETRA() in exec/softmmu_template.h which is included in cputlb.c. The TCG interpreter failed because the values returned by GETRA() were no longer explicitly set to 0. The redefinition of GETRA() introduced here fixes this. In addition, GETPC_ADJ which is also used in exec/softmmu_template.h is set to 0. Both changes reduce the compiled code size for cputlb.c by more than 100 bytes, so the normal TCG without interpreter also profits from the reduced code size and slightly faster code.

2014-06-02vnc: refuse to set a password with VNC_AUTH_NONEGerd Hoffmann
Current code silently changes the authentication settings in case you try to set a password without password authentication turned on. This is bad. Return an error instead. If we want allow changing auth settings at runtime this should be done explicitly using a separate monitor command, not as side effect of set_passwd. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2014-06-02usb: add usb_pick_speedGerd Hoffmann
We can pick the usb port speed in generic code, by looking at the port and device speed masks and looking for the fastest match. So add a function to do exactly that, and drop the speed setting code from usb_desc_attach as it isn't needed any more. This way we can set the device speed before calling port->ops->attach, which fixes some xhci hotplug issues. https://bugzilla.redhat.com/show_bug.cgi?id=1046873 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
