Photon and Atoms inflation distribution to Validators

How will the inflationary tokens (Photons and Atoms to start) be distributed to Validators?

Round number Assumptions:
100 Validators
500 new Photons minted per hour
12% annual Atom inflation (1% per month)

If 100 Validators, does each Validator get 1/100 (1%) of the new Photons created per hour? So each Validator get 5 Photons per hour, in addition to whatever fee tokens they collect?

Or is the Photon inflation received based on amount staked?

Same question for Atoms.

I read the latest blog, and it seems Photon may not be available until we pass a governance proposal to activate it.

about the inflation of ATOM, in the code, the provision is calculated every hour and then added to the staking pool, as:

provision = total supply * 12% / (hours in a year)

Link to code @suyu ?

preliminary mechanism here:

cosmos/cosmos-sdk/blob/develop/x/stake/keeper/inflation.go

package keeper

import (
	sdk "github.com/cosmos/cosmos-sdk/types"
	"github.com/cosmos/cosmos-sdk/x/stake/types"
)

const (
	hrsPerYr  = 8766         // as defined by a julian year of 365.25 days
	precision = 100000000000 // increased to this precision for accuracy
)

var hrsPerYrRat = sdk.NewRat(hrsPerYr)

// process provisions for an hour period
func (k Keeper) ProcessProvisions(ctx sdk.Context) types.Pool {

	pool := k.GetPool(ctx)
	pool.Inflation = k.NextInflation(ctx)
