2016-08-14ps2: Remove stale check for timeout warning on resetKevin O'Connor1-3/+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>
2016-08-11tpm: Append to TPM2 log the hashes used for PCR extensionKevin O'Connor2-93/+103
Modify the function that writes the TPM logs to take the same digest passed to tpm_extend. Update the tpm2 acpi log header to describe the digest format. Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
2016-08-10tpm: Extend tpm20_extend to support extending to multiple PCR banksStefan Berger2-23/+171
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.

2016-08-10tpm: Refactor tpml_digest_values_sha1 structureStefan Berger2-11/+15
Refactor the tpml_digest_values_sha1 structure so we can later cast it to the more general tpml_digest_values structure. Move the count member into this structure. Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>
2016-08-10tpm: Restructure tpm20_extend to use buffer and take hash as parameterStefan Berger2-10/+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>

2016-08-05pvscsi: Use high memory for ringsDana Rubin1-4/+4
Avoid using the scarce ZoneLow memory. This limits max number of pvscsi controllers. As driver runs in 32bit mode, use ZoneHigh allocation instead. Signed-off-by: Dana Rubin <dana.rubin@ravellosystems.com> Signed-off-by: Shmulik Ladkani <shmulik.ladkani@ravellosystems.com>

2016-07-07smp: restore MSRs on S3 resumePaolo Bonzini3-14/+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.

2016-07-01fw/msr_feature_control: add support to set MSR_IA32_FEATURE_CONTROLHaozhong Zhang2-11/+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>

2016-06-01fw/pci: Add support for mapping Intel IGD via QEMUAlex Williamson1-0/+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.

2016-03-21sdcard: skip detection of PCI sdhci controllers if etc/sdcard usedMatt DeVillier1-0/+5
Some BayTrail ChromeOS devices have the eMMC controller hidden (thus requiring the use of etc/sdcard), while others do not, making it problematic to have a single payload which serves all devices properly. Therefore, if the CBFS contains etc/sdcard entries, skip detection of any visible PCI sdhci controllers in order to avoid duplicate entries in the boot menu.

2016-02-29tpm: Write logs in TPM 2 formatKevin O'Connor2-13/+109
Add support for the TPM 2 format of log messages. Write the logs in the format that is appropriate for the version of the host's TPM. For TPM 1.2 write it in the 'pcpes' structure's format, for TPM 2 in the new TPM 2 format. By using this method we can keep the API interface on systems with a TPM 2 even though applications pass in the 'pcpes' structures directly. The log will still be written in the appropriate format. The TPM 2 log contains a TPM 1.2 type of entry of event type EV_NO_ACTION and entry of type TCG_EfiSpeIdEventStruct as the first entry. This is described in the EFI specification (section 5.3): Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
2016-02-19tpm: Unify tpm_fill_hash()/tpm_log_extend_event() and use in BIOS interfaceKevin O'Connor1-41/+36
Don't call tpm_fill_hash() or tpm_log_extend_event() from any internal code (ie, tpm_add_measurement_to_log). The internal code does not require the additional checks that these functions provide. Unify the tpm_fill_hash() and tpm_log_extend_event() into a new function hash_log_extend(), and use this function only in the 16bit BIOS interface code. With the code now specific to the BIOS interface it can more easily return a BIOS specific error return code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
2016-02-05tpm: Filter TPM commands in passthrough APIStefan Berger2-1/+20

2016-02-05tpm: Implement tpm20_menuStefan Berger2-1/+133
In the TPM 2 menu we currently only allow to run the TPM2_Clear operation. For this we follow the TCG Physical Presence Interface Specification to be found here: http://www.trustedcomputinggroup.org/resources/tcg_physical_presence_interface_specification Table 3 shows the 'Clear' operation and the sequence of commands to send.

2016-02-05tpm: Implement tpm20_prepbootStefan Berger2-2/+153
Implement tpm20_preboot. Here we set the platform password to a random password that prevents higher layers (OS) to get this password. This avoids bad things like users clearing the TPM, erasing EK (primary key) certificates, changing the primary key etc. The clearing of the TPM will still be possible through the TPM 2 menu.

2016-02-05tpm: Implement tpm20_set_timeoutsStefan Berger2-0/+37
The TIS timeouts for TPM 2 are different than for TPM 1.2. Also the timeouts indicating a failed TPM 2 command are different. Further, the command durations and timeouts cannot be read from the device. We take the command timeout values for short, medium, and long running commands from table 15 of the following specification: TCG PC Client Platform TPM Profile (PTP) Specification http://www.trustedcomputinggroup.org/resources/pc_client_platform_tpm_profile_ptp_specification The values should work for all physical TPMs. The tricky thing with virtualized environments is that the values may need to be longer for a system where a vTPM cannot get sufficient cycles. So a future patch _may_ need to multiply those values here with some factor. Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>

2016-02-05tpm: Prepare code for TPM 2 functionsStefan Berger1-112/+185
This patch prepares the tcgbios.c file for extension with TPM 2 specific code by: o prefixing all TPM 1.2 specific functions with tpm12_ o where necessary, introduce switch statements in tpm_ - prefixed functions; here we branch into TPM versions specific code o introduce tpm_ - prefixed functions where necessary; mostly in those cases where tpm12_ functions are too large and where the tpm_ function then only holds the switch statement o leave FIXMEs where we need to write TPM 2 specific code; subsequent patches will replace those FIXMEs Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>
2016-02-05tpm: Factor out tpm_extendStefan Berger1-4/+14

Extend the probing of the interface with TPM 2 specifics. Use the new interface ID register of the TIS to check whether a TPM 1.2 or a TPM 2 is underneath. We select the TIS if possible and lock it so we can issue commands during S3 for example and prevent the OS from changing to CRB type of interface.
