* kbd: Ignore fake shift keysKevin O'Connor2016-09-121-0/+6
| | | | | | | | AT keyboards can produce "fake" shift keys on some extended events. It's not necessary to process these artificial events as the actual extended keys are detected directly. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* kbd: Suppress keys without mappingsKevin O'Connor2016-09-121-3/+2
| | | | | | | | | Don't warn if a key without a mapping is pressed - it's known that some keys aren't mapped to keycodes. Suppress these keys instead of sending 0x0000 to the keyboard buffer - as 0x0000 can confuse some programs. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* kbd: Implement extended keycode mappings for keypad-enter and keypad-/Kevin O'Connor2016-09-121-0/+15
| | | | | | | | On a 101-key keyboard the keypad enter and keypad '/' keys have unique BIOS keycodes that are distinct from the main keyboard enter and '/' keys. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* kbd: Implement 101-key keyboard keycode mappingKevin O'Connor2016-09-121-28/+40
| | | | | | | | | The current keyboard code only supports the keycode mappings for 83-key keyboards (plus handling for alt-esc and f11/f12). Add a more complete mapping of keycodes for 101-key keyboards. This adds more alt key and ctrl key mappings. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* ps2: Remove stale check for timeout warning on resetKevin O'Connor2016-08-141-3/+1
| | | | | | | | | Commit 4ce5d207 removed the code to wait for a possible second byte from a keyboard reset command, but it did not remove the extra check when warning in ps2_recvbyte(). Remove the now stale code in ps2_recvbyte(). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

| | | | | | | | | | Extend the tpm20_extend function to support extending a hash to multiple PCR banks. The sha1 hash that's being extended into the sha256 bank for example, will be filled with zero-bytes to the size of a sha256 hash.

* tpm: Restructure tpm20_extend to use buffer and take hash as parameterStefan Berger2016-08-102-10/+13
| | | | | | | | | Restructure the tpm20_extend function to use a buffer for the command to send to the TPM. The size of the buffer is calculated from the size of tpm2_req_extend structure and the appended SHA1 hash. Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>

* vgabios: Simplify scroll logicKevin O'Connor2016-07-213-69/+64
| | | | | | | | | Introduce a new function vgafb_scroll() to scroll a window on the screen and update vgabios.c to use only that function for scrolling. This makes the low-level vgafb_move_chars() and vgafb_clear_chars() local to vgafb.c, and it simplifies the callers. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* smp: restore MSRs on S3 resumePaolo Bonzini2016-07-073-14/+38
| | | | | | | | | | | | | | | | | Currently the MTRRs and MSR_IA32_FEATURE_CONTROL are not restored on S3 resume. Because these have to be applied to all processors, SMP setup has to be added to S3 resume. There are two differences between the boot and resume paths. First, romfile_* is not usable in the resume paths so we separate out the remaining common code to a new smp_scan function. Second, smp_msr has to be walked on the BSP as well, so we extract that out of handle_smp and into a new function smp_write_msrs. Then, resume can call smp_write_msrs on the BSP followed by smp_scan to initialize the APs.

* vgabios: Don't check for special case of page==0xff on external callsKevin O'Connor2016-07-042-11/+5
| | | | | | | | | | | The original "lgpl vgabios" internally used page=0xff as a mechanism for specifying the current page. It also would allow int1013 calls to externally specify bh==0xff for the current page. However, there is no documentation supporting this as an externally available feature. SeaVGABIOS does not need the internal shortcut; this patch removes the code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* vgabios: Remove special case of dh==0xff in handle_1013()Kevin O'Connor2016-07-041-7/+1
| | | | | | | | | | | The original "lgpl vgabios" had a special case for dh==0xff in its int1013 (write string) code. There does not appear to be any VGABIOS documentation supporting this as an externally available feature. It appears this was for its own internal use when writing its strings to the screen. SeaVGABIOS doesn't use this hack; this patch removes it from the code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* fw/msr_feature_control: add support to set MSR_IA32_FEATURE_CONTROLHaozhong Zhang2016-07-012-11/+21
| | | | | | | | | | | | | OS usually expects BIOS to set certain bits in MSR_IA32_FEATURE_CONTROL for some features (e.g. VMX and LMCE). QEMU provides a fw_cfg file "etc/msr_feature_control" to advise bits that should be set in MSR_IA32_FEATURE_CONTROL. If this file exists, SeaBIOS will set the advised bits in that MSR.

| | | | | | | | | virtio regions can also be accessed using a window in pci cfg space. Add support for it. Enable it in case the virtio regions are mapped high (above 4g), so direct mmio access doesn't work for us even in 32bit mode. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

* fw/pci: Add support for mapping Intel IGD via QEMUAlex Williamson2016-06-011-0/+48
| | | | | | | | | | | | | | | | | | | | | | QEMU provides two fw_cfg files to support IGD. The first holds the OpRegion data which holds the Video BIOS Table (VBT). This needs to be copied into reserved memory and the address stored in the ASL Storage register of the device at 0xFC offset in PCI config space. The OpRegion is generally 8KB. This file is named "etc/igd-opregion". The second file tells us the required size of the stolen memory space for the device. This space requires 1MB alignment and is generally either 1MB to 8MB depending on hardware config, but may be hundreds of MB for user specified stolen memory. The base address of the reserved memory allocated for this is written back to the Base Data of Stolen Memory register (BDSM) at PCI config offset 0x5C on the device. This file is named "etc/igd-bdsm-size". QEMU documents these fw_cfg entries in docs/igd-assign.txt.
