2019-02-04bootsplash: Added support for 16/24/32bpp in one functionJoseph Pacheco-Corwin3-14/+13
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().

2018-12-17output: Avoid thunking to 16bit mode in printf() if no vgabiosKevin O'Connor1-0/+3
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>
2018-12-10qemu: avoid debug prints if debugcon is not enabledStefano Garzarella4-2/+21
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.

2018-09-18SeaVGABios/cbvga: Fix bpp for coreboot framebufferMatt DeVillier1-2/+8
Commit 4b42cc4 [SeaVGABios/cbvga: Advertise correct pixel format] neglected to wrap the cbfb mask size components in GET_FARVAR(), which resulted in a bogus value for bpp, breaking output on most/all devices. Fix this by adding GET_FARVAR() as appropriate. Additionally, some newer ChromeOS devices still fail even with this fix, so fall back to using the coreboot reported bit depth if the calculated valid is invalid. TEST: build/boot a variety of devices (google/[reef,eve], purism/librem_skl) using coreboot framebuffer init, verify SeaBIOS boot menu prompt visible.

2018-08-23nvme: fix I/O queue length calculation overflowMatt DeVillier1-2/+2
Commit cd47172 changed the I/O queue length calculation to use the Maximum Queue Entries Supported (MQES) value from the capabilities register, plus one, with a maximum value of NVME_PAGE_SIZE. An unintended effect from this is that due to length being an unsigned 16-bit int, a MQES value of 0xFFFF yields a length of zero, resulting in the queue allocation failing. Fix this by changing length to a u32. TEST: build/boot on a Purism Librem13v2 with a MyDigitalSSD BPX NVMe drive, which reports a MQES of 0xFFFF. Verify NVMe drive present in boot menu and OS boots successfully. Signed-off-by: Matt DeVillier <matt.devillier@puri.sm>

2018-07-15ssdt: Fix building of legacy acpi tables on current iasl compilerKevin O'Connor2-2/+2
Recent versions of the iasl compiler raise an error if the table id is longer than 8 characters. Older versions of iasl would silently truncate the table id to 8 characters. Change the ssdt-misc and ssdt-pcihp files to use an 8 character id - this should not directly impact the generated aml code as the table id was already being truncated - but may help those wishing to manually compile the tables.

2018-06-22qemu: add qemu ramfb supportGerd Hoffmann5-14/+189
Add support for qemu ramfb. This is a simple boot framebuffer device, with normal ram being used to back the framebuffer and fw_cfg being used to configure the device. Use case (on x86): boot display for vgpu devices (which neither emulate vga nor have a vgabios). Sharing fw_cfg code with seabios turned out to be difficuilt due to various dependencies the code has on infrastructure which only seabios has. So include a copy of the code here, with those dependencies removed and also stripped down because we don't need a non-dma fallback here. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2018-02-22shadow: Don't invoke a shutdown on reboot unless in a reboot loopKevin O'Connor1-11/+16
Old versions of KVM would map the same writable copy of the BIOS at both 0x000f0000 and 0xffff0000. As a result, a reboot on these machines would result in a reboot loop. So, the code attempts to check for that situation and invoke a shutdown instead. Commit b837e68d changed the check to run prior to the first reboot. However, this broke reboots on the QEMU isapc machine type. Change the reboot loop check to only be invoked after at least one reboot has been attempted. Reported-by: Daniel P.

2018-02-15floppy: Send 4 sense interrupt commands during controller initializationNikolay Nikolov1-1/+14
During initialization, real floppy controllers need 4 sense interrupt commands to clear the interrupt status (this represents the transition from "not ready" to "ready" for each of the four virtual floppy drives), instead of just one. This is described in detail in section 7.4 - Drive Polling of the Intel 82077AA datasheet. Signed-off-by: Nikolay Nikolov <nickysn@users.sourceforge.net>
2018-02-15floppy: Wait for the floppy motor to reach a stable speed, after startingNikolay Nikolov1-2/+11
When starting up the floppy motor, wait for a certain amount of time, so that it can spin up and reach a stable speed. This delay is skipped, if the motor was already running (which can happen, since the floppy motor is intentionally kept spinning for 2 seconds after the previous floppy operation completes).

2018-02-07floppy: Use timer_check() in floppy_wait_irq()Nikolay Nikolov1-4/+5
Use timer_check() instead of using floppy_motor_counter in BDA for the timeout check in floppy_wait_irq(). The problem with using floppy_motor_counter was that, after it reaches 0, it immediately stops the floppy motors, which is not what is supposed to happen on real hardware. Instead, after a timeout (like in the end of every floppy operation, regardless of the result - success, timeout or error), the floppy motors must be kept spinning for additional 2 seconds (the FLOPPY_MOTOR_TICKS). So, now the floppy_motor_counter is initialized to 255 (the max value) in the beginning of the floppy operation. For IRQ timeouts, a different timeout is used, specified by the new FLOPPY_IRQ_TIMEOUT constant (currently set to 5 seconds - a fairly conservative value, but should work reliably on most floppies). After the floppy operation, floppy_drive_pio() resets the floppy_motor_counter to 2 seconds (FLOPPY_MOTOR_TICKS). This is also consistent with what other PC BIOSes do.
