2012-08-02x86emu: fix jump_near_IMM to handle DATA: flag correctlyStefan Reinauer
Before (data flag ignored -> broken): 66 DATA: e944f1 JMP 1ff6 After (fixed): 66 DATA: e944f1ffff JMP 00001ff8 This subtle difference in the length of decoded instruction meant that the VBE call jumped to the routine setting AX=0x14F (VBE Failed) instead of the routine that set AX=0x4F (VBE success). The ability to run the same code in vm86 significantly aided the debugging of this issue. Those X.org developers who would like to drop vm86 better take special care towards _all_ vesa bugs, as those will expose further issues.

2012-08-01Intel Sandybridge and UMA: use mmio_resource()Kyösti Mälkki
With SandyBridge northbridge code, uma_memory_size was reset to zero before variable MTRRs were set. This means MTRR setup routine did not previously create a un-cacheable hole for uma. Keep the behaviour that way, mmio_resource() has a prerequisuite that the new region does not overlap with any cacheable ram_resource(). The result is not optimal setup in the number of used MTRRs, but continue with this approach until MTRR algorithm is improved.

2012-07-27Intel and GFXUMA: fix MTRR and use uma_resource()Kyösti Mälkki
Commit 2d42b340034ff005693482ef9ca34ce3e0f08371 changed the variable MTRR setup and removed compensation of uma_memory_size in the cacheable memory resources. Since the cacheable region size was no longer divisible by a large power of 2, like 256 MB, this caused excessive use of MTRRs. As first symptoms, slow boot with grub and poor user response. As a solution, register the actual top of low ram with ram_resource(), and do not subtract the UMA/TSEG regions from it. TSEG may require further work as the original did not appear exactly right to begin with. To have UMA as un-cacheable, use uma_resource().

It explicitly does not support "TDP up" at the moment. PSSS: method is added to assist in searching the _PSS table for the appropriate entry that corresponds to the desired max non-turbo ratio. STND: Set TDP Down from Nominal. This will limit CPU to the TDP down configuration by sequencing the required changes in the right order. STDN: Set TDP Nominal from Down. This will set the CPU back to nominal configuration by sequencing the required changes in the correct (reverse) order. This does not introduce any functional changes and must be paired with additional changes to be useful. The current configured TDP can be checked to see that the transition to/from a desired level is successful. > mmio_read8 0xfed15f50 0x00 # TDP-Nominal > mmio_read8 0xfed15f50 0x01 # TDP-Down Change-Id: I31a2f30cc9d134cc5eee980ae9288ae45e71c6e6 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1344 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

The existing NVS variable for PPCM will be used to select a dynamic max P-state. By itself this does not change existing behavior because the NVS PPCM variable is initialized to zero.

2012-07-26ELOG: Support GSMI in CPT/PPT southbridge SMI handlerDuncan Laurie
In order to support the GSMI interface the SMI handler needs to find and use the state save area from the same CPU that initiated the SMI. In this case it is a synchronous SMI resulting form an IO write to port 0xB2. To find the right CPU state save area iterate over the region until the "IO Misc Info" field reports the expected value and then proceed to use that state save area. This is needed because the coreboot SMI handler only executes on one core, and that core is non-deterministic. It is likely that the core executing the C SMM handler is not the same one that actually did the IO write to 0xB2 and generated the SMI. The GSMI parameter buffer is passed as a pointer to EBX in the tate save area, and the GSMI command is extracted from EAX before it is used as the return value. This interface is tested by enabling CONFIG_GOOGLE_GSMI in the kernel and generating events and verifying that they end up in the event log. 159 | 2012-06-23 16:22:45 | Kernl Event | Clean Shutdown 184 | 2012-06-23 17:14:05 | Kernl Event | Oops 185 | 2012-06-23 17:14:05 | Kernl Event | Panic Change-Id: Ic121ea69e9f50c88467c435e095c3e3629989806 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1317 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-07-26ELOG: Add support for SMM and kernel GSMI driverDuncan Laurie
The linux kernel contains an SMI driver that was written by me (Duncan) and upstreamed a couple years ago called GSMI. This driver will format a parameter buffer and pass pointers to this parameter buffer to the SMI handler. It uses this to generate events for kernel shutdown reasons: Clean, Panic, Oops, etc. This function expects to be passed pointers into the SMM state save area that correspond to the prameter buffer and the return code, which are typically EAX and EBX. The format of the parameter buffer is defined in the kernel driver so we implement the same interface here in order to be compatible. GSMI_CMD_HANDSHAKE: this is an early call that it does to try and detect what kind of BIOS is running. GSMI_CMD_SET_EVENT_LOG: this contains a parameter buffer that has event type and data. The kernel-specific events are translated here and raw events are passed through as well which allows any run-time event to be added for testing. GSMI_CMD_CLEAR_EVENT_LOG: this command clears the event log. First the gsmi driver must be enabled in the kernel with CONFIG_GOOGLE_GSMI and then events can be added via sysfs and events are automatically generated for various kernel shutdown reasons. These can be seen in the event log as the 'Kernel Event' type: 169 | 2012-06-23 15:03:04 | Kernl Event | Clean Shutdown 181 | 2012-06-23 16:26:32 | Kernl Event | Oops 181 | 2012-06-23 16:26:32 | Kernl Event | Panic Change-Id: Ic0a3916401f0d9811e4aa8b2c560657dccc920c1 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1316 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

coreboot used to pass some information to u-boot in the coreboot table and other information in a modified flat device tree. Since the FDT code was never upstreamed and removed from our tree, u-boot was changed to get the information it needs from the coreboot table alone. However, in the process of this change only the vboot shared data structure was passed on by coreboot, so when u-boot tried to update the ChromeOS specific ACPI entries, it would accidently overwrite the vboot data. This patch passes on the ChromeOS specific ACPI data structure instead of the vboot shared data. Another change to u-boot will teach it how to get to the vboot shared data from there.

2012-07-24CPU: Set flex ratio to nominal TDP ratio in bootblockDuncan Laurie
CPUs with configurable TDP will run the TSC at the max non-turbo ratio for the maximum TDP value, which can cause issues if another TDP is desired. To deal with this we set the flex ratio to the nominal TDP ratio early in the boot and then configure the Soft Reset Data registers so the PCH can tell the CPU what frequency to run at after a reset. This is done very early in the bootblock because it is necessary to reset the system after setting a flex ratio. The end result is that the TSC will now increment at the max non-turbo frequency for the nominal TDP. On some system with 1.8GHz CPU ensure that the kernel detects the CPU speed as ~1800mhz rather than ~2300mhz: > dmesg | grep "MHz processor" [ 0.004000] Detected 1795.801 MHz processor.

2012-07-24ELOG: Add support for flash based event logDuncan Laurie
This is based around the SMBIOS event log specification but expanded with OEM event types to support more specific and relevant system events. It requires flash storage and a minimum 4K block (or flash block size) that should be allocated in the FMAP. A copy of the event log is maintained in memory for convenience and speed and the in-memory copy is written to flash at specific points. The log is automatically shunk when it reaches a configurable full threshold in order to not get stuck with a full log that needs OS help to clear. ELOG implements the specification published here: http://code.google.com/p/firmware-event-log/wiki/FirmwareEventLogDesign And is similar to what we use in other firmware at Google. This implementation does not support double-buffered flash regions. This is done because speed is valued over the log reliability and it keeps the code simpler for the first version. This is a large commit and by itself it just provides a new driver that is made available to coreboot. Without additional patches it is not very useful, but the end result is an event log that will contain entries like this: 171 | 2012-06-23 16:02:55 | System boot | 285 172 | 2012-06-23 16:02:55 | EC Event | Power Button 173 | 2012-06-23 16:02:55 | SUS Power Fail 174 | 2012-06-23 16:02:55 | System Reset 175 | 2012-06-23 16:02:55 | ACPI Wake | S5 Change-Id: I985524c67f525c8a268eccbd856c1a4c2a426889 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: http://review.coreboot.org/1311 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

Break the stack checking out into a separate function, which we will later use for the APs.
