[RFC v5 00/68] support vector extension v1.0

[RFC v5 00/68] support vector extension v1.0

[frank.chang]

From: Frank Chang <frank.chang@sifive.com>

This patchset implements the vector extension v1.0 for RISC-V on QEMU.

This patchset is sent as RFC because RVV v1.0 is still in draft state.
v2 patchset was sent for RVV v0.9 and bumped to RVV v1.0 since v3 patchset.

The port is available here:
https://github.com/sifive/qemu/tree/rvv-1.0-upstream-v5

You can change the cpu argument: vext_spec to v1.0 (i.e. vext_spec=v1.0)
to run with RVV v1.0 instructions.

Note: This patchset depends on two other patchsets listed in Based-on
      section below so it might not able to be built unless those two
      patchsets are applied.

Changelog:

v5
  * refactor RVV v1.0 check functions.
    (Thanks to Richard Henderson's bitwise tricks.)
  * relax RV_VLEN_MAX to 1024-bits.
  * implement vstart CSR's behaviors.
  * trigger illegal instruction exception if frm is not valid for
    vector floating-point instructions.
  * rebase on riscv-to-apply.next.

v4
  * remove explicit float flmul variable in DisasContext.
  * replace floating-point calculations with shift operations to
    improve performance.
  * relax RV_VLEN_MAX to 512-bits.

v3
  * apply nan-box helpers from Richard Henderson.
  * remove fp16 api changes as they are sent independently in another
    pathcset by Chih-Min Chao.
  * remove all tail elements clear functions as tail elements can
    retain unchanged for either VTA set to undisturbed or agnostic.
  * add fp16 nan-box check generator function.
  * add floating-point rounding mode enum.
  * replace flmul arithmetic with shifts to avoid floating-point
    conversions.
  * add Zvqmac extension.
  * replace gdbstub vector register xml files with dynamic generator.
  * bumped to RVV v1.0.
  * RVV v1.0 related changes:
    * add vl<nf>re<eew>.v and vs<nf>r.v vector whole register
      load/store instructions
    * add vrgatherei16 instruction.
    * rearranged bits in vtype to make vlmul bits into a contiguous
      field.

v2
  * drop v0.7.1 support.
  * replace invisible return check macros with functions.
  * move mark_vs_dirty() to translators.
  * add SSTATUS_VS flag for s-mode.
  * nan-box scalar fp register for floating-point operations.
  * add gdbstub files for vector registers to allow system-mode
    debugging with GDB.

[RFC v5 05/68] target/riscv: rvv-1.0: introduce writable misa.v field

[frank.chang]

From: Frank Chang <frank.chang@sifive.com>

Implementations may have a writable misa.v field. Analogous to the way
in which the floating-point unit is handled, the mstatus.vs field may
exist even if misa.v is clear.

Removing the gen_goto_tb can't be right all by itself.

I think you want to be sharing the code between vsetvl and vsetvli now.  Just
pass in a TCGv value to a common helper.

Oops, I think I somehow mess up the commits.
This commit should only contain: + mark_vs_dirty(ctx); change.
The - gen_goto_tb(ctx, 0, ctx->pc_succ_insn); should be included and
replaced by:
+ tcg_gen_movi_tl(cpu_pc, ctx->pc_succ_insn);
+ lookup_and_goto_ptr(ctx);
in later commit: target/riscv: rvv-1.0: update check functions.

The only difference now between vsetvl and vsetvli is the format of zimm
and s2 fields.
But they have different formats and are queried by different functions,
i.e. s2 = tcg_const_tl(a->zimm); and gen_get_gpr(s2, a->rs2);

Is there any elegant way to retrieve the values of zimm and s2 by shared
common codes?

Yes, like I (too briefly) described:

static bool do_vsetvl(DisasContext *ctx,
                      int rd, int rs1, TCGv s2)
{
    // existing contents of trans_vsetvl
    // do continue to free s2.
}

static bool trans_vsetvl(DisasContext *ctx, arg_vsetvl *a)
{
    TCGv s2 = tcg_temp_new();
    gen_get_gpr(s2, a->rs2);
    return do_vsetvl(ctx, a->rd, a->rs1, s2);
}

static bool trans_vsetvli(DisasContext *ctx, arg_vsetvli *a)
{
    TCGv s2 = tcg_const_tl(a->zimm);
    return do_vsetvl(ctx, a->rd, a->rs1, s2);
}

Oops, I misunderstood what the "helper function" you meant.
I thought it was the helper function in vector_helper.c.
I'll update the codes in the next version patchset.

[RFC v5 11/68] target/riscv: rvv-1.0: remove MLEN calculations

[frank.chang]

From: Frank Chang <frank.chang@sifive.com>

As in RVV 1.0 design, MLEN is hardcoded with value 1 (Section 4.5).
Thus, remove all MLEN related calculations.

[RFC v5 13/68] target/riscv: rvv-1.0: add VMA and VTA

[frank.chang]

From: Frank Chang <frank.chang@sifive.com>

Introduce vma and vta fields in vtype register.

According to RVV 1.0 spec (section 3.3.3):

When a set is marked agnostic, the corresponding set of destination
elements in any vector or mask destination operand can either retain
the value they previously held, or are overwritten with 1s.

So, either vta/vma is set to undisturbed or agnostic, it's legal to
retain the inactive masked-off elements and tail elements' original
values unchanged. Therefore, besides declaring vta/vma fields in vtype
register, also remove all the tail elements clean functions in this
commit.

[RFC v5 13/68] target/riscv: rvv-1.0: add VMA and VTA

[frank.chang]

From: Frank Chang <frank.chang@sifive.com>

Introduce vma and vta fields in vtype register.

According to RVV 1.0 spec (section 3.3.3):

When a set is marked agnostic, the corresponding set of destination
elements in any vector or mask destination operand can either retain
the value they previously held, or are overwritten with 1s.

So, either vta/vma is set to undisturbed or agnostic, it's legal to
retain the inactive masked-off elements and tail elements' original
values unchanged. Therefore, besides declaring vta/vma fields in vtype
register, also remove all the tail elements clean functions in this
commit.

[RFC v5 15/68] target/riscv: introduce more imm value modes in translator functions

[frank.chang]

From: Frank Chang <frank.chang@sifive.com>

Immediate value in translator function is extended not only
zero-extended and sign-extended but with more modes to be applicable
with multiple formats of vector instructions.

* IMM_ZX:         Zero-extended
* IMM_SX:         Sign-extended
* IMM_TRUNC_SEW:  Truncate to log(SEW) bit
* IMM_TRUNC_2SEW: Truncate to log(2*SEW) bit

Signed-off-by: Frank Chang <frank.chang@sifive.com>

[RFC v5 15/68] target/riscv: introduce more imm value modes in translator functions

[frank.chang]

From: Frank Chang <frank.chang@sifive.com>

Immediate value in translator function is extended not only
zero-extended and sign-extended but with more modes to be applicable
with multiple formats of vector instructions.

* IMM_ZX:         Zero-extended
* IMM_SX:         Sign-extended
* IMM_TRUNC_SEW:  Truncate to log(SEW) bit
* IMM_TRUNC_2SEW: Truncate to log(2*SEW) bit

Signed-off-by: Frank Chang <frank.chang@sifive.com>

[RFC v5 16/68] target/riscv: rvv:1.0: add translation-time nan-box helper function

[frank.chang]

From: Frank Chang <frank.chang@sifive.com>

* Add fp16 nan-box check generator function, if a 16-bit input is not
  properly nanboxed, then the input is replaced with the default qnan.
* Add do_nanbox() helper function to utilize gen_check_nanbox_X() to
  generate the NaN-boxed floating-point values based on SEW setting.
* Apply nanbox helper in opfvf_trans().

[RFC v5 42/68] target/riscv: rvv-1.0: integer add-with-carry/subtract-with-borrow

[frank.chang]

From: Frank Chang <frank.chang@sifive.com>

* Only do carry-in or borrow-in if is masked (vm=0).
* Remove clear function from helper functions as the tail elements
  are unchanged in RVV 1.0.

[RFC v5 62/68] target/riscv: add "set round to odd" rounding mode helper function

[frank.chang]

From: Frank Chang <frank.chang@sifive.com>

helper_set_rounding_mode() is responsible for SIGILL, and "round to odd"
should be an interface private to translation, so add a new independent
helper_set_rod_rounding_mode().

[RFC v5 67/68] target/riscv: implement vstart CSR

[frank.chang]

From: Frank Chang <frank.chang@sifive.com>

* Update and check vstart value for vector instructions.
* Add whole register move instruction helper functions as we have to
  call helper function for case where vstart is not zero.

Signed-off-by: Frank Chang <frank.chang@sifive.com>

--

Perhaps we can remove the probe functions in vector_helper.c to align with
the hardware's behavior, which raise the memory access exceptions and
update vstart value at the exact processing vector element.

[RFC v5 67/68] target/riscv: implement vstart CSR

[frank.chang]

From: Frank Chang <frank.chang@sifive.com>

* Update and check vstart value for vector instructions.
* Add whole register move instruction helper functions as we have to
  call helper function for case where vstart is not zero.

Signed-off-by: Frank Chang <frank.chang@sifive.com>

--

Perhaps we can remove the probe functions in vector_helper.c to align with
the hardware's behavior, which raise the memory access exceptions and
update vstart value at the exact processing vector element.

[RFC v5 68/68] target/riscv: trigger illegal instruction exception if frm is not valid

[frank.chang]

From: Frank Chang <frank.chang@sifive.com>

If the frm field contains an invalid rounding mode (101-111),
attempting to execute any vector floating-point instruction, even
those that do not depend on the rounding mode, will raise an illegal
instruction exception.

Call gen_set_rm() with DYN rounding mode to check and trigger illegal
instruction exception if frm field contains invalid value at run-time
for vector floating-point instructions.

[RFC v5 68/68] target/riscv: trigger illegal instruction exception if frm is not valid

[frank.chang]

From: Frank Chang <frank.chang@sifive.com>

If the frm field contains an invalid rounding mode (101-111),
attempting to execute any vector floating-point instruction, even
those that do not depend on the rounding mode, will raise an illegal
instruction exception.

Call gen_set_rm() with DYN rounding mode to check and trigger illegal
instruction exception if frm field contains invalid value at run-time
for vector floating-point instructions.
