link/graphics: New state machine
This is a new state machine. It is more programmatic, in the
case of auxio, and has much more symbolic naming, and very few
"magic" numbers, except in the case of undocumented settings.
As before, the 'pre-computed' IO ops are encoded in the iodefs
table. A function, run, is passed and index into the table and
runs the ops.
A new operator, I, has been added. When the I operator is hit,
run() returns the index of the next operator in the table.
The i915lightup function runs the table. All the AUX channel ops
have been removed from the table, however, and are now called as
functions, using the previously committed auxio function.
The iodefs table has been grouped into blocks of ops, which end in
an I operator. As the lightup function progresses through startup,
and the run() returns, the lightup function performs aux channel
operations.
This code is symbolic enough, I hope, that it will make haswell
graphics bringup simpler.
i915io.c, and the core of the code in i915lightup.c, were
programatically generated, starting with IO logs from the DRM
startup code in the kernel. It is possible to apply the tools that
do this generation to newer IO logs from the kernel.

link/graphics: New state machine
This is a new state machine. It is more programmatic, in the
case of auxio, and has much more symbolic naming, and very few
"magic" numbers, except in the case of undocumented settings.
As before, the 'pre-computed' IO ops are encoded in the iodefs
table. A function, run, is passed and index into the table and
runs the ops.
A new operator, I, has been added. When the I operator is hit,
run() returns the index of the next operator in the table.
The i915lightup function runs the table. All the AUX channel ops
have been removed from the table, however, and are now called as
functions, using the previously committed auxio function.
The iodefs table has been grouped into blocks of ops, which end in
an I operator. As the lightup function progresses through startup,
and the run() returns, the lightup function performs aux channel
operations.
This code is symbolic enough, I hope, that it will make haswell
graphics bringup simpler.
i915io.c, and the core of the code in i915lightup.c, were
programatically generated, starting with IO logs from the DRM
startup code in the kernel. It is possible to apply the tools that
do this generation to newer IO logs from the kernel.

link/graphics: New state machine
This is a new state machine. It is more programmatic, in the
case of auxio, and has much more symbolic naming, and very few
"magic" numbers, except in the case of undocumented settings.
As before, the 'pre-computed' IO ops are encoded in the iodefs
table. A function, run, is passed and index into the table and
runs the ops.
A new operator, I, has been added. When the I operator is hit,
run() returns the index of the next operator in the table.
The i915lightup function runs the table. All the AUX channel ops
have been removed from the table, however, and are now called as
functions, using the previously committed auxio function.
The iodefs table has been grouped into blocks of ops, which end in
an I operator. As the lightup function progresses through startup,
and the run() returns, the lightup function performs aux channel
operations.
This code is symbolic enough, I hope, that it will make haswell
graphics bringup simpler.
i915io.c, and the core of the code in i915lightup.c, were
programatically generated, starting with IO logs from the DRM
startup code in the kernel. It is possible to apply the tools that
do this generation to newer IO logs from the kernel.

/* GTT is the Global Translation Table for the graphics pipeline.
|
|
|
|
|
* It is used to translate graphics addresses to physical
|
|
|
|
|
* memory addresses. As in the CPU, GTTs map 4K pages.
|
|
|
|
|
* There are 32 bits per pixel, or 4 bytes,
|
|
|
|
|
* which means 1024 pixels per page.
|
|
|
|
|
* There are 4250 GTTs on Link:
|
|
|
|
|
* 2650 (X) * 1700 (Y) pixels / 1024 pixels per page.
|
|
|
|
|
* The setgtt function adds a further bit of flexibility:
|
|
|
|
|
* it allows you to set a range (the first two parameters) to point
|
|
|
|
|
* to a physical address (third parameter);the physical address is
|
|
|
|
|
* incremented by a count (fourth parameter) for each GTT in the
|
|
|
|
|
* range.
|
|
|
|
|
* Why do it this way? For ultrafast startup,
|
|
|
|
|
* we can point all the GTT entries to point to one page,
|
|
|
|
|
* and set that page to 0s:
|
|
|
|
|
* memset(physbase, 0, 4096);
|
|
|
|
|
* setgtt(0, 4250, physbase, 0);
|
|
|
|
|
* this takes about 2 ms, and is a win because zeroing
|
|
|
|
|
* the page takes a up to 200 ms. We will be exploiting this
|
|
|
|
|
* trick in a later rev of this code.
|
|
|
|
|
* This call sets the GTT to point to a linear range of pages
|
|
|
|
|
* starting at physbase.

link/graphics: New state machine
This is a new state machine. It is more programmatic, in the
case of auxio, and has much more symbolic naming, and very few
"magic" numbers, except in the case of undocumented settings.
As before, the 'pre-computed' IO ops are encoded in the iodefs
table. A function, run, is passed and index into the table and
runs the ops.
A new operator, I, has been added. When the I operator is hit,
run() returns the index of the next operator in the table.
The i915lightup function runs the table. All the AUX channel ops
have been removed from the table, however, and are now called as
functions, using the previously committed auxio function.
The iodefs table has been grouped into blocks of ops, which end in
an I operator. As the lightup function progresses through startup,
and the run() returns, the lightup function performs aux channel
operations.
This code is symbolic enough, I hope, that it will make haswell
graphics bringup simpler.
i915io.c, and the core of the code in i915lightup.c, were
programatically generated, starting with IO logs from the DRM
startup code in the kernel. It is possible to apply the tools that
do this generation to newer IO logs from the kernel.
