+# Sandy Bridge Raminit
+
+## Introduction
+
+This documentation is intended to document the closed source memory controller
+hardware for Intel 2nd Gen (Sandy Bride) and 3rd Gen (Ivy Bridge) core-i CPUs.
+
+The memory initialization code has to take care of lots of duties:
+1. Selection of operating frequency
+* Selection of common timings
+* Applying frequency specific compensation values
+* Read training of all populated channels
+* Write training of all populated channels
+* Adjusting delay networks of address and command signals
+* DQS training of all populated channels
+* Programming memory map
+* Report DRAM configuration
+* Error handling

+### SMBIOS type 17
+The SMBIOS specification allows to report the memory configuration in use.
+On GNU/Linux you can run `# dmidecode -t 17` to view it.
+Example output of dmidecode:
+
+```
+Handle 0x0045, DMI type 17, 34 bytes
+    Memory Device
+	Array Handle: 0x0042
+	Error Information Handle: Not Provided
+	Total Width: 64 bits
+	Data Width: 64 bits
+	Size: 8192 MB
+	Form Factor: DIMM
+	Set: None
+	Locator: ChannelB-DIMM0
+	Bank Locator: BANK 2
+	Type: DDR3
+	Type Detail: Synchronous
+	Speed: 933 MHz
+	Manufacturer: 0420
+	Serial Number: 00000000
+	Asset Tag: 9876543210
+	Part Number: F3-1866C9-8GSR
+	Rank: 2
+	Configured Clock Speed: 933 MHz
+```
+The memory frequency printed by dmidecode is the active memory frequency. It's
+**not** the double datarate and it's **not** the one encoded maximum frequency
+in each DIMM's SPD.
+
+> **Note:** This feature is available since coreboot 4.4
+
+### MRC cache
+The name *MRC cache* might be missleading as in case of *Native ram init*
+there's no MRC, but for historical reasons it's still named *MRC cache*.
+The MRC cache is part of flash memory that is writeable by coreboot.
+At the end of the boot process coreboot will write the RAM training results to
+flash for future use, as RAM training is time intensive. Storing the results
+allows to boot faster on normal boot and allows to support S3 resume,
+as the RAM training results can't be stored in RAM (you need to configure
+the memory controller first to access RAM).
+
+The MRC cache needs to be invalidated in case the memory configuration has
+been changed. To detect a changed memory configuration the CRC16 of each DIMM
+is stored to MRC cache.
+> **Note:** This feature is available since coreboot 4.4
+
+### Error handling
+As of writing the only supported error handling is to disable the failing
+channel and restart the memory training sequence. It's very likely to succeed,
+as memory channels operate independent of each other.
+In case no DIMM could be initilized coreboot will halt. The screen will stay
+black until you power of your device. On some platforms there's additional
+feedback to indicate such an event.
+
+If you find `dmidecode -t 17` to report only half of the memory installed,
+it's likely that a fatal memory init failure had happened.
+It is assumed, that a working board with less physical memory, is much better,
+than a board that doesn't boot at all.
+
+> **Note:** This feature is available since coreboot 4.5
+
+Try to swap memory modules and or try to use a different vendor. If nothing
+helps you could have a look at capter [Debuggin] or report a ticket
+at [ticket.coreboot.org]. Please provide a full RAM init log,
+that has been captured using EHCI debug.
+
+To enable extensive RAM training logging enable the Kconfig option
+`DEBUG_RAM_SETUP`
+#### Lenovo Thinkpads
+Lenovo Thinkpads do have an additional feature to indicate that RAM init has
+failed and coreboot has died (it calls die() on fatal error, thus the name).
+The Kconfig options
+`H8_BEEP_ON_DEATH`
+`H8_FLASH_LEDS_ON_DEATH`
+enable blinking LEDs and enable a beep to indicate death.
+
+> **Note:** This feature is available since coreboot 4.7
+
+## Debugging
+It's recommended to use an external debugger, such as serial or EHCI debug
+dongle. In case of failing memory init the board might not boot at all,
+preventing you from using CBMEM.

+```
+## SPD
+The [SPD](https://de.wikipedia.org/wiki/Serial_Presence_Detect "Serial Presence Detect")
+located on every DIMM is factory program with various timings. One of them
+specifies the maximum clock frequency the DIMM should be used with. The
+operating frequency is stores as fixed point value (tCK), rounded to the next
+smallest supported operating frequency. Some
+[SPD](https://de.wikipedia.org/wiki/Serial_Presence_Detect "Serial Presence Detect")
+contains additional and optional
+[XMP](https://de.wikipedia.org/wiki/Extreme_Memory_Profile "Extreme Memory Profile")
+data, that stores so called "performance" modes, that advertises higher clock
+frequencies.
+
+## XMP profiles
+At time of writing coreboot's raminit is able to parse XMP profile 1 and 2.
+Only **XMP profile 1** is being used in case it advertises:
+* 1.5V operating voltage
+* The channel's installed DIMM count doesn't exceed the XMP coded limit
+
+In case the XMP profile doesn't fullfill those limits, the regular SPD will be
+used.
+> **Note:** XMP Profiles are supported since coreboot 4.4.
+
+It is possible to ignore the max DIMM count limit set by XMP profiles.
+By activating Kconfig option `NATIVE_RAMINIT_IGNORE_XMP_MAX_DIMMS` it is
+possible to install two DIMMs per channel, even if XMP tells you not to do.
+
+> **Note:** Ignoring XMP Profiles limit is supported since coreboot 4.7.
+
+## Soft fuses
+Every board manufacturer does program "soft" fuses to indicate the maximum
+DRAM frequency supported. However, those fuses don't set a limit in hardware
+and thus are called "soft" fuses, as it is possible to ignore them.
+
+> **Note:** Ignoring the fuses might cause system instability !
+
+On Sandy Bride *CAPID0_A* is being read, and on Ivybridge *CAPID0_B* is being
+read. coreboot reads those registers and honors the limit in case the Kconfig
+option `CONFIG_NATIVE_RAMINIT_IGNORE_MAX_MEM_FUSES` wasn't set.
+Power users that want to let their RAM run at DRAM's "stock" frequency need to
+enable the Kconfig symbol.
+
+It is possible to override the soft fuses limit by using a board-specific
+[devicetree](#devicetree) setting.
+
+> **Note:** Ignoring max mem freq. fuses is supported since coreboot 4.7.
+
+## Hard fuses
+"Hard" fuses are programmed by Intel and limit the maximum frequency that can
+be used on a given CPU/board/chipset. At time of writing there's no register
+to read this limit, before trying to set a given DRAM frequency. The memory PLL
+won't lock, indicating that the chosen memory multiplier isn't available. In
+this case coreboot tries the next smaller memory multiplier until the PLL will
+lock.
+
+## Devicetree
+The devicetree register `max_mem_clock_mhz` overrides the "soft" fuses set
+by the board manufacturer.
+
+By using this register it's possible to force a minimum operating frequency.
+
+## Reference clock
+While Sandybride supports 133 MHz reference clock (REFCK), Ivy Bridge also
+supports 100 MHz reference clock. The reference clock is multiplied by the DRAM
+multiplier to select the DRAM frequency (SCK) by the following formula:
+
+ REFCK * MULT = 1 / DCK
+
+> **Note:** Since coreboot 4.6 Ivy Bridge supports 100MHz REFCK.

+## Multiplier selection
+coreboot select the maximum frequency to operate at by the following formula:
+```
+if devicetree's max_mem_clock_mhz > 0:
+     freq_max := max_mem_clock_mhz
+else:
+     freq_max := soft_fuse_max_mhz
+
+for i in SPDs:
+     freq_max := MIN(freq_max, ddr_spd_max_mhz[i])
+```
+
+As you can see, by using DIMMs with different maximum DRAM frequencies, the
+slowest DIMMs' frequency will be selected, to prevent over-clocking it.
+
+The selected frequency gives the PLL multiplier to operate at. In case the PLL
+locks (see Take me to [Hard fuses](#hard_fuses)) the frequency will be used for
+all DIMMs. At this point it's not possible to change the multiplier again,
+until the system has been powered off. In case the PLL doesn't lock, the next
+smaller multiplier will be used until a working multiplier will be found.

+# Read training
+
+## Introduction
+
+This chapter explains the read training sequence done on Sandy Bride and
+Ivy Bridge memory initialization.
+
+Read training is done to compensate the skew between DQS and SCK and to find
+the smallest supported roundtrip delay.
+
+Every board does have a vendor depended routing topology, and can be equip
+with any combination of DDR3 memory modules, that introduces different
+skew between the memory lanes. With DDR3 a "Fly-By" routing topology
+has been introduced, that makes the biggest part of DQS-SCK skew.
+The memory code measures the actual skew and actives delay gates,
+that will "compensate" the skew.
+
+When in read training the DRAM and the controller are placed in a special mode.
+On every read instruction the DRAM outputs a predefined pattern and the memory
+controller samples the DQS after a given delay. As the pattern is known, the
+actual delay of every lane can be measured.
+
+The values programmed in read training effect DRAM-to-MC transfers only !

+## Hardware
+The hardware does have delay logic blocks that can delay the DQ / DQS of a
+lane/rank by one or multiple clock cylces and it does have delay logic blocks
+that can delay the signal by a multiple of 1/64th DCK per lane.
+
+All delay values can be controlled via software by writing registers in the
+MCHBAR.
+
+## IO phase
+
+The IO phase can be adjusted in [0-512) * 1/64th DCK. Incrementing it by 64 is
+the same as Incrementing IO delay by 1.
+
+## IO delay
+Delays the DQ / DQS signal by one or multiple clock cycles.
+
+### Roundtrip time
+The roundtrip time is the time the memory controller waits for data arraving
+after a read has been issued. Due to clock-domain crossings, multiple
+delay instances and phase interpolators, the signal runtime to DRAM and back
+to memory controller defaults to 55 DCKs. The real roundtrip time has to be
+measured.
+
+After a read command has been issued, a counter counts down until zero has been
+reached and activates the input buffers.
+
+The following pictures shows the relationship between those three values.
+The picture was generated from 16 IO delay values times 64 timA values.
+The highest IO delay was set on the right-hand side, while the last block
+on the left-hand side has zero IO delay.

+
+[timA_lane0-3_rt53]: timA_lane0-3_rt53.png
+
+As you can see the signal has some jitter as every sample was taken in a
+different loop iteration. The result register only contains a single bit per
+lane.
+
+## Algorithm
+### Steps
+The algorithm finds the roundtrip time, IO delay and IO phase. The IO phase
+will be adjusted to match the falling edge of the preamble of each lane.
+The roundtrip time is adjusted to an minimal value, that still includes the
+preamble.
+
+### Synchronize to data phase
+
+The first measurement done in read-leveling samples all DQS values for one
+phase [0-64) * 1/64th DCK. It then searches for the middle of the low data
+symbol and adjusts timA to the found phase and thus the following measurements
+will be aligned to the low data symbol.
+The code assumes that the initial roundtrip time causes the measurement to be
+in the alternating pattern data phase.
+
+### Finding the preamble
+After adjusting the IO phase to the middle of one data symbol the preamble will
+be located. Unlike the data phase, which is an alternating pattern (010101...),
+the preamble consists of two high data cycles.
+
+The code decrements the IO delay/RTT and samples the DQS signal with timA
+untouched. As it has been positioned in the middle of the data symbol, it'll
+read as either "low" or "high".
+
+If it's "low" we are still in the data phase.
+If it's "high" we have found the preamble.
+
+The roundtrip time and IO delay will be adjusted until all lanes are aligned.
+The resulting IO delay is visible in the picture below.
+
+**roundtrip time: 49 DCKs, IO delay (at blue point): 6 DCKs**
+![timA for lane0 - lane3, finding minimum roundtrip time][timA_lane0-3_discover_420x]
+
+[timA_lane0-3_discover_420x]: timA_lane0-3_discover_420x.png
+
+**Note: The sampled data has been shifted by timA. The preamble is now
+in phase.**
+
+## Fine adjustment
+
+As timA still points the middle of the data symbol an offset of 32 is added.
+It now points the falling edge of the preamble.
+The fine adjustment is to reduce errors introduced by jitter. The phase is
+adjusted from `timA - 25` to `timA + 25` and the DQS signal is sampled 100
+times. The fine adjustment finds the middle of each rising edge (it's actual
+the falling edge of the preamble) to get the final IO phase. You can see the
+result in the picture below.
+
+![timA for lane0 - lane3, fine adjustment][timA_lane0-3_adjust_fine]
+
+[timA_lane0-3_adjust_fine]: timA_lane0-3_adjust_fine.png
+
+Lanes 0 - 2 will be adjusted by a phase of -10, while lane 3 is already correct.
