In contrast to other allocations made by pvscsi_init_rings(), ring_desc is only used internally by SeaBIOS (not passed to device-controller) and there is not restriction which force it to be page aligned.

In order to speed up the boot phase, we can check the QEMU debugcon device, and disable the writes if it is not recognized. This patch allow us to save around 10 msec (time measured between SeaBIOS entry point and "linuxboot" entry point) when CONFIG_DEBUG_LEVEL=1 and debugcon is not enabled.

It is not necessary to call the vgabios if no vgabios has been installed. This reduces the amount of hardware accesses on qemu when the bios is not initializing the display hardware, and it can reduce the boot time by a couple of milliseconds. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

Specifically added support for 16 and 32bpp files, in addition to 24bpp. The function bmp_show() in bmp.c has had the hardcoded check for 24bpp replaced with a general bpp check that uses a % to check for remainder, and returns 1 if the remainder is >0. The previous method for adjusting the BMP data (raw_data_format_adjust_24bpp) relied on a preset 3*bytes_per_line_src, this has been changed and the multiplication is now performed in the function's arguments. This change still allows someone else to reuse the same function for 1/2/4bpp support if necessary. The file util.h has been modified to reflect this decision. The changes to raw_data_format_adjust() is based on an abandoned patch by Gert Menke (submitted March 14, 2017), credit to them for that change and the addition of *bpp to bmp_get_info().

Make sure to clear the token before reuse as it may otherwise have an incorrect toggle setting. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

…anks Implement a TPM 2.0 menu item that allows a user to toggle the activation of PCR banks of the TPM 2.0. After successful activation we shut down the TPM 2.0 and reset the machine. Background: A TPM 2.0 may have multiple PCR banks, such as for SHA1, SHA256, SHA384, SHA512, and SM3-256. One or multiple of those banks may be active (by factory for example) and modifying the set of active PCR banks is only possible while in the firmware since it requires platform authorization. Platform authorization is not possible for a user when in the OS since the firmware generates a random password for the platform authorization before booting the system and it throws that password away.

Supports qemu emulated ati cards. They have been added in qemu 4.0. Acceleration support (in qemu) is pretty rough still. A simple framebuffer works fine though. Available models: * ati rage 128 pro * ati rv100 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
